Material Property panel not showing up in Create App

Omniverse General Discussion

I checked the extension was enabled but not showing up in the UI when I select any material.

Can we get some context for your materials? If you are using a material like OmniPBR, selecting either the Material or Shader should show the adjustable parameters:

If you are using an Unreal-exported Material then there must be parameters defined in the Unreal material graph for any to show up in the material’s property window.

This is all I see when I select a OmnoPBR material:

I am running Create in HydraStorm mode.

The error on command prompt:
(Looks unrelated to the issue, but even this shouldn’t be there becase PhysX extensions are also enabled)

These extensions are enabled:

Also grid is not rendering in Hydra Storm mode in the viewport. And the statistics panel is also not showing anything, everything is 0.

@LouRohan
Any idea why this is happening?

I did a little digging and it looks like MDL materials are not supported in the HydraStorm render mode. We’re discussing internally if the MDL material properties should actually display or not, but I know for sure that only UsdPreviewSurface materials and display colors are supported in the Viewport with Storm (same as in usdview).

I was able to add a USD Preview Surface material from the Create menu and see its properties here:

And I loaded a mesh with USD Preview Surface materials and could view/edit more advanced properties:

Thanks for the response.
So, I am guessing, for now we should use USD Preview Surface materials only(in HDStorm mode and maybe in RTX mode as well to maintain consistency.).

That’s correct.If you’re looking for a material that’s supported in both, UsdPreviewSurface is recommended.
