How to showcase your 3D model on the 3D product configurator

How to showcase your 3D model on the 3D product configurator

Welcome back to another lesson of
getting started on Expivi. In the previous lesson we saw how we can import
a 3D model and setup the basic… …configuration for different variations
on a product. In this lesson I’m going to show you an overview of the
showcase, where you can set up… …different lighting and the
presentation of the product on your website… … to the customers.
So this part is actually about the presentation and the… …visualization of the materials, the
lighting and how the product is… …generally presented to the customers.
So after importing and configurating our 3D… …model, we go to the Showcase, which is the next step.
When you go to the showcase… …there is the possibility that you don’t directly get to see the product… …Just like the example on my screen. This is actually because the 3d model that has been imported… …wasn’t drawn in meters, which means it’s
too big for my scene. So if you encounter that kind of problem where you have your modeltree inside your… …configuration and your 3D
model is shown in the modeltree, but it’s not… …visible inside the showcase there is a
big chance that it has been integrated in… …the showcase, but it’s just too small or
too big to be presented in the view. Use your mouse buttons to navigate inside the Showcase. With the right mouse button you can pan or drag and move the scene around. With the scroll button you can zoom in and zoom out. With the left mouse
button you can rotate around the product. If it turns out your product is too small or too big… …coming into the showcase, we have a few different parts where we can insert. We have the scene hierarchy with a scene representation of the things we added to the scene. We have the properties panel and the toolbar panel. When you go to the showcase for the first time, the scene hierarchy will be closed. I can open this by making selections in the scene hierarchy. If I don’t see the product I can select a configurable node… …so this is actually the 3D model that we have imported in the previous step… …and you can select this 3D model to change the scaling of that model. I’m going to make the scaling
smaller to see what it will look like. The size and scaling doesn’t matter
that much as long as you are able to see… …the product and are able to set up the
lighting the way you want. I’m going to reduce the scaling so I have a little more space in the scene to move around. I’m scaling it down. It has been cut down now. I’m going to change the one material that is transparent. This is the basic setup of my scene. Before this product can be presented… …inside the preview or on your web shop we need to set up a few things. The first one is the lighting and the second
is the camera. By setting the lighting you can determine where the light will shine on the object The camera determines from what angle customers get to see the product. We can change these settings by
going to “Insert”. There are few different options that we can
add to a product. For this product we want to add a light and we have a few different options to choose from. Directional light allows you to choose a direction. Ambient is a generic light that
will reflect light on every angle of the product… …it doesn’t have any position or direction… …so there’s generic light intensity on the entire product. Hemispheric light is
automatically placed inside the scene… …when you open your product and the
hemispheric light has an interesting property. It has a light object and a hemispheric light object… …which stands for the ground color and the normal color. The difference between those two is… …that there are two different colors that
are shining on the object. One is coming from the side that is in front of the object… …and the other one is the ground color which is coming from the back. The front side is the color that the object receives from the light point. This is the side that is facing the light point. The ground color is the light that is lit on the back side (or opposite side of the light point) of the object This gives you a little freedom in playing around with the lighting. You can choose if you want to have a little more general light surfaces… …on the front or back side
when there is not enough lighting from the… …other light types that you have added to
the scene. I’m going to add a directional light by going to “Insert” and selecting “Directional. It will appear directly inside my scene
hierarchy. Then I can select the light and move it around. One thing to keep in mind about the
light… …is that you can not rotate around lights that have a direction. You can only move them around. If you want to change the point where the light direction is shining at… … you need to select the light of the item, go to its “properties” and click “toggle target”. This will toggle the
re-positioning of the object or the… …target that it is pointing at. So I can decide on what target the light is pointing or in which direction it is reflecting. The target is actually where the light is
reflecting at. With the directional light I have to set up the reflection from this position. I’m moving it a little more up so that I can see that the light is shining from that direction which is the… …direction of the directional
light (which was just added). And now I am going to decrease the hemispheric light
which is just the general light that has… …been shining on every part of the product. If I remove or set the intensity at zero… …you can see that at the moment
only the directional light is… …shining from one direction.
So you can see everything on that side… …is lit and everything at the other
side is completely black. That’s because there’s no light shining on that part (from any direction). The Hemispheric light will light the object from both both sides so it will light up from the… …side that’s already being lit as well as the opposite (dark) side. I’m going to decrease it a little bit. Usually you want to have the color of the light it is aiming at… And the front inside you want to have little bit lower… …because we already have
a light shining from the directional light from this side. I want to light
the backside a little more. I don’t want to light the front side
any more because otherwise it will be.. overexposed on one side which is already receiving directional light. So now I have
added lighting to the object and I can see… …that it’s properly lit and next I’m
going to add a camera. So first go to “Insert” again and select “Camera”, it will be added to the Scene Graph immediately. I can also select
every object that has been added to the… …scene or I can also just click the object with my left mouse button… …and it gets selected directly. The camera is being placed from where we view the… …product in the “Preview” or in the web shop. The product will be viewed… …from the camera that has been set in the
scene. In order to select and place the camera to the point that I want the camera to be aiming at… …or from where you are viewing the product… …I can either just move the camera around or change it’s direction. The camera also has a target transform which allows the toggling on the target, this is the focus where… …the camera is actually focused on. I want the camera to be focused on the exact center of the object. I can also set the position of the camera in another way so I can just move around my view… …place the object and set the view… …where I want to be viewing the object
from and then just set the camera. When I select the “set camera” button I click “confirm” and it will place the camera at… …the position from where I was looking at the object. If I hadn’t transformed… …the focus of the camera, so if it had been
set at zero… …if I’d go back and select the view
camera, so it would actually show me the… …view position I see that the object is a
little higher and it’s not properly centered. That is because the focus of
the camera is still at the center so.. … to change that when the camera is
selected I need to go to the properties… …to the focus point and change the focus
to the place where I want the camera to… …be focused at. So place it at the center
of the object and now the camera will be… …aimed at the exact center of that
object. So when I go back and view the object… …I see that it is aiming at the
point I have set as the focus of the camera. Another part of the the camera is how you
want to view the product. We have the options “Orbit” and “First-person”. Orbit means that the camera will rotate around its focus point. So to give you an overview of that I’ll show you what I’ve done in here… …don’t forget to save all of the
changes if you are going to navigate to… …other tabs, otherwise you will lose all
of the work that you have done inside the scene. So I’ve saved that and if I go
to “Preview” I see that my lighting has… …been set up and my camera as well. And going back
to what I was telling you about the camera controller… …is the Orbit and the First
person, so since I have set my focus… …point of my camera to the center of this
object and I have selected the controller of… …the camera as orbit I can orbit around
the object. If I go back and re-select the camera… …and change the controller to
first-person and save it. Go back to the Preview and I will see… …that I have a
first-person view that is like a… …person looking at the object and looking
up and down. So you have two different options for the camera as a
controller and how you want the… …customer to view the product when
they navigate around the product… …inside the visualization area. I have added my camera,
I have added my lights… … the next thing I can do is changing the
background of the view. In order to do that I need to select the layer
that I’m currently working on. The default layer that has been generated during the first step… …I can just select that layer, go to the view
background options… … here I can select different options. You can use “Transparent” when you want to have the background of the 3d model or… … your visualization to be transparent. So you can actually see
through it on your website. By selecting color you can select different
colors as the background for your product. We can select any type of color that
we want. There is also the possibility to select an image… …so when I select an
image, it will place this image on the background. Click “Assign” and you can select an
image. You can select an image from the media library will pop up.. …out of all of the images that are
available. I can just select any image from the media library and use it as my background. So for example if I select that one… …it will place that one as my background. And if
I search for another image that I have… …for example, the street, select it and
we’ll preview that image as background. Another option that you have is the cube
map, which is a skybox. So in here you can have six-sided images… …to present
your product as if it was inside an environment. I’m going to
choose a color, set this as one color… …for the background of the product. Save changes
And then again, when I go to the Preview… …we can view the product from the
first person camera view or… …if I go back and change the camera… …to use orbit as controller, save changes and… …go back to preview I can rotate around it. It has the correct background color… …lighting on it and I can switch
between the different variations that… are available for the product, which I set up
previously on my configuration. So, there is one more thing that we
are going to look into, the materials of the object. In order to change the
different options of my product I can… …select the product node, that’s the root
node that is inside the scene hierarchy… I can go to the attributes and
switch between the different variations… …that I have as my attributes. When I have
selected each of the variations I want… …I can also select a part on the object itself and
it will load the material properties… …of the part that I have selected. In here I can then change the different colors… that I want to have and
directly get visual feedback of how the… …product is going to look. You have a
variety of different options where you… …can select from and there is also a
variety of different types that you can… setup as material
type, like physical based shading… …standard shading and some other types
that we have. But we will cover that in other tutorials. Again: if I change
something inside the material I need to… …save changes for the material, because if I select a different part… …it will reset the material properties that
I have changed. So when I select part of an object… …I can change the color,
save it… …and when I click away,
all changes that were made will remain. So the initial… I am going to change that as well,
it has some property on it. With that I have actually set up all
of the basics that are required to set up… …the visual presentation of the product. The only thing it needs are a few good lights, …a little bit of changes on the
materials and a camera. When you have set that up… … you are ready to go and preview
the product and actually see the product… …inside Expivi’s platform. I can preview
the product here or I can go to my account… …which is your (team account) I can select a product… I can actually directly see the product
on the platform and choose from all of… …the different variations that I have set
up for my product. If you’re using an e-commerce platform like Magento… …Shopify, WooCommerce
or other websites or shopping platforms… …you can use one of our plugins
to preview the product inside this platform as well. Or you can download our
Augmented Reality app to view the… …product also directly in Augmented Reality. In the next lessons we are going to show you… …how you can set up different
materials and different sets of material selections … …of the product, to make it
even more realistic and also to add the… …options for the customer to select
between different materials. Thank you very much and until next time! Byebye!
