Issue with custom mesh.

[lcaraffa]

Hi! I would like to know if it's possible to make a scan from every kind of scene? I'm trying to use the "lego scene" blender file from the original "nerf" dataset (file available here : https://drive.google.com/file/d/1yDB7Pmo2KSPw2d0J7E6FHvb-sU0DdTvX/view?usp=sharing), but it's not working I'm interested about the X,Y,Z and the intensity of every scan, can you help me?

My setup : the standalone blender 2.93 with the add-on (working well with the example scene). I first did "make single user" on the mesh (I had an issue with it) Then i had this error : "closestHit.color = materialProperty.color AttributeError: 'NoneType' object has no attribute 'color'" Do you know if there is any hack in order to make the scan possible? (

Thank you very much for your help. ps : Thanks for sharing your code, it would be very helpful for me if I can make this scan.

Hey @lcaraffa, thanks for your interest. The problem is that you use some non supported materials. As described here, you can currently only use Princinpled BSDF and Glass BSDF as material. Looking at the console logging, I get many errors like this:

Unknown material type for object Plane.001!
EMISSION
Unknown material type for object Plane.001!
MIX_SHADER

Emission, BSDF_DIFFUSE and Mix Shader from your scene are unfortunately not implemented yet. So you would need to swap your materials with some Princinpled BSDF based ones.

@ln-12 thank you vm for your quick answer! I'll change the material and try again. Laurent

Is this issue still relevant or can I close it?
