Ply norm consideration about pcx HOT 11 OPEN

I have never seen a point cloud that has normals. How did you create it?

Meshlab produced it for me, and i don't want to ignore / disregard them.
I saw some mentions on Unity forums and such about it as well.

Could you provide a .ply point cloud data file with normals?

Sure,
I imported an example PLY from your project, and exported it through meshlab
Guanyin2.zip

Because it was created from a PLY without normals originally, the normals don't add information, but taking a PLY with normal information and disregarding it affects the lighting from different camera angles and different lightings.

I realized that it needs some changes in the basic design of the importer. It requires some amount of time to support it.

I'd like to add this to the to-do list of the project. Unfortunately, I can't afford time for it at the moment. I'll revisit it when I get free time.

Sure, I get it.
Any chance you can give a brief explanation about how to use the norms in the shader?
Maybe this can help me proceed, and perhaps contribute.

Add float3 normal : NORMAL; to Attributes.

Then you can use the normal in the vertex shader.

Thanks
The trouble I had was the math of how to use the values of the normals :)

I have PLY with normals as well. Perhaps I could help get this working?

I would also love to use ply normals in the VFX graph, in the same way you would with a pcache file

from pcx.

It would be great to use normals from the .ply file to set the particle direction in VFX graph. Would this require generating a normals texture, in addition to colour and position maps?
