Title: USD Stage object is rendered without smoothing.
Post by: gandhics on 2023-01-27, 09:22:21

3dsMax USD beta has fall back mode for Stage object.
Until Corona supports native rendering of USD Stage. This is a great way to get Stage render support for free. I tested with Corona. But, it is rendering without smoothing like the attached image.

I tested on Scanline, Arnold, FinalRender. All doesn't have this issue. Viewport also shows current smoothing.

You can download the USD file from here.

Renders fine here. I just downloaded USDZ file from your link, unpacked it, imported to a scene and hit render - no modifications were needed for it to work.

Hi,

I can confirm that this is working fine just out of the box. Also, I noticed that you are using Corona 9. I recommend upgrading to Corona 9 HF 1, as it includes the latest bug fixes and improvements. If there were any bugs in the previous version, they may have already been resolved in the newer one.

Hi,

Do you have any updates here?
It would also be a good idea to "Reset Settings" in Render Settings > Scene tab.

You need to load with Stage object not importing.

from File name.
Or, you can make Stage object directly.

Any news about this?

Gandhics is correct.
When you use the USD Stage to load a USD file as a reference, you need to use the 'Assign USD Materials' (which is the fallback mode) because Corona doesn't yet support native USD rendering. Then, you will notice the absence of smoothing in the rendering. Vray and Arnold, however, are working fine.

Thumbs up for a fix.
