« on: 2022-01-16, 18:38:27 »
Hi,
Corona version is 7 hotfix 1 and 3dsmax2021.
Text and images to reproduce:
1) OSL: Checker with UVW set to Map Channel 1.
2) OSL: Checker with UVW set to World.
3) OSL: Noise with UVW set to World.
4) Mix using a CoronaMix. Ok.
5) Mix using a OSL: Mix (color). Ok.
6) CoronaAO set to Inside.
7) Using the OSL: Noise as AO distance. Ok.
8) Mix using a CoronaMix. Ok.
9) Mix using a OSL: Mix (color). Issue.
I think there is an issue with UVW coordinates.
Only CoronaMix seems to be able to correctly read UVW coordinates passing through CoronaAO.
