Exporting color scale renderings from Ladybug simulations outside of Rhino after baking can be challenging as most formats tend to lose the colored information. What steps can we take to address this issue?
Bake the results from Ladybug.
Export the 3D file to WRML
Check Vertex Colors
Import the WRML file
The file arrives black
Change Material to Attribute to see the color gradient
Transferring Attribute to Texture
First unwrap the geometry
Select shape -> UV Editing
Object Mode -> Edit Mode
Be sure that all faces are selected (it should be orange)
UV -> Smart UV Project
In Shader Editor
Add a Color Attribute, Right Button click to reveal Col
Link Color to Base Color
Add an Image Texture
Click New and choose 2048×2048 resolution
Switch Evee to Cycles
Down to Bake
Bake Type Diffuse
Contribution : Color
Select Texture image panel AND Geometry and then click Bake.
It takes time…
Connect Texture Node to Base Color and activate Color Texture
Secure save the image
Reload if necessary
This is workflow to create a scene in Coraulis. It is done in Blender, but can be realised any similar 3D software. The first step consists in creating a “landscape”. We used the Geometry Nodes to create it, but can be done the usual way or with another software equivalently. It is then lit which can also be done anywhere else. Then the camera is animated along a path. The rendering process uses the Equirectangular 360 Camera which is built in Blender. But we can find the same camera in Cinema 4D, 3DsMax or Twinmotion. The 360 film is then recut to fit Coraulis requirements. Step by step with Blender, C4D or Max, we can create an amazing experience with plying with the context, the movements or the light.

Spatial offers several possibilities for High end real time online rendering. Let’s see how to prepare our 3D files to get the best of it. As it is trans software, we will use at least 4 of them in parallel to get the same results. Let’s remember, it’s not the software but the workflow that is taken into account.
We will start from this tutorial on the Spatial web page that helped us to start. https://support.spatial.io/hc/en-us/articles/4418819002004
Basic geometry to start.
Let’s set up a basic scene for our tests : a wall, a floor, a cube, sphere, and Nefertiti (why not) downloaded here : https://www.openculture.com/2019/11/download-stunning-3d-scans-of-the-bust-of-nefertiti.html
