Re: Capture AOV driving me crazy

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.

Re: Is there a way to convert a obj into a Vectron

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.

Re: Is there a way to convert a obj into a Vectron

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

Re: Is there a way to convert a obj into a Vectron

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 ...

Re: Is there a way to convert a obj into a Vectron

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.

Re: Adding resolution override into batch render window

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.

Re: The many core issues holding Octane back


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 ...

Re: OctaneRender® 2026.1 Alpha 1 [current 2026.1]

As an option, can we use ComfyUI as the local AI?

Right now in the development version, yes, it can talk to a local ComfyUI install. We have a few test nodes working.
We are also planning on having a remote Comfy server option to make it easier. I don't know at this point if both will work in ...

Re: OctaneRender® 2025.1 Beta 1 [current 2025.1]

OK, the first one you posted appears to be a DirectX style Normal map. To make it work we must invert the green channel.
But we have to do this on the raw data before it gets linearized by the engine. Set it to "non-color data", add a "Channel inverter" node and set it to invert the green channel ...
