Hi, how to properly export the model with 'Corona for 3ds Max' textures from 3ds Max (with usdz plugin installed),
after exporting, textures are missing in the preview
-
I dont use usd (yet) but from the documentation (https://help.autodesk.com/view/3DSMAX/2024/ENU/?guid=GUID-CC8C2874-1F7C-45A3-B21A-6F8FE85516D5)it looks like you need either Physical, USD Preview Surface or MaterialX materials (not Corona materials). If you are using only Corona Physical materials you can try my script (https://forum.corona-renderer.com/index.php?topic=40480.30) to convert to Autodesk Physical materials (not sure how Physical materials behave in usd but you can try).
You could also put a request to Corona team to implement a converter/exporter similar to Vray 6. Currently I dont see it on the trello roadmap (https://trello.com/b/EfPE4kPx/corona-road-map).

thanks for the answer, I'll check it out, maybe it will help, but maybe someone had a similar problem and will write something...

Just tested it using Physical materials, seems to work just fine exporting to .usd
Just remember to put a normal node before your normal texture in the bump slot. Or apparently you can use the PBR Metal/Gloss, GLTF materials too. My script that converts Corona to Physical also does the normal node for you.

thanks for your time, but I have a 'newbie' question, how to run the script... to change the material /via Maxscript button -> Utilities?/
