Marking portions of texture with semantic labels

Omniverse Synthetic Data Generation (SDG)

Is it possible to assign semantic labels to specific regions within a texture file in Isaac Sim?

For example — suppose I have a cube that uses a single texture image mapped across all its faces. When I capture semantic data or render a semantic segmentation pass, I would like the resulting labels to correspond to regions in the texture image itself (e.g., based on the RGB values or specific marked areas within the texture).

In other words, can the semantic labeling be defined at the texture level rather than per-mesh or per-material?

Thanks!

Can someone please respond on this. Thanks.

Hi @Blue_Dot The short answer is unfortunately no, there isn’t a way to annotate via textures. We have an internal feature request for this, but I can’t speak to if or when it might be addressed. That said, I’ll make a note that this was requested again.

Thanks for bringing this up.
