All three files I found online do not work in Octane. Perhaps there are some special settings that need to be enabled for them to work properly.


These appear to be regular point cloud PLY files, not gaussian splats.
Some viewers might detect that and load them as regular point clouds like ...

Did I understand correctly that the Chaos Texture can only be used this way — directly connected to each map — and that there’s no option to generate a reusable projection once and then apply it across different maps?


Yes that is correct, at the moment it cannot be used as you would use a ...

Matcap projection improvements
The matcap projection doesn't work like a matcap is supposed to work.
If you create a sphere with the matcap projection and move it to the side of the view the projection looks off.
Instead, using a ray direction set to tangent does generate a correct matcap if you ...

Maybe you have a piece of glass or some other geometry between the camera and the object such that the object stays fully visible to the camera in the render but when isolated through the custom AOV it doesn't see it correctly.

Yeah it works with the original mesh polygons, not the displaced ones. You might try to use a Vectron displacement and put a noise in its Texture field. It will use the linear projection (XYZ -> UVW) though, not the Mesh UVs.

I don't think that conversion retains the UVs at this point unfortunately.

Yes the source OBJ makes a difference. Because it will try to figure out what is the interior vs exterior of the model. If it's not an enclosed shape it can break the ray marching. You might see massive see-through artifacts when looking at the surface. Normally when the ray marching goes slightly ...

You can use a "Mesh volume SDF" node to convert an OBJ to a signed distance field. Then you can combine this with vectron primitives or other SDF objects with the union/subtraction/ink, etc. operators.

I know you are talking about the Batch rendering global script but have you tested with the Batch render job? It has "Override resolution" built in.

1. Handling of instance data

* Use of instance attributes requiring Octane to write data to an image file(????) thus limiting the amount of instances that can have attributes to the amount of pixels in the image


I think you can think of it as a buffer of attributes in GPU memory, it just ...
