Corona Bitmap + Triplanar

(1/1)

John_Do:
Hi,

Another weird bug with the Corona Bitmap shader and the Triplanar shader. Native Bitmap gives the expected result regardless of the setup, but Corona Bitmap seems to rely on UVs if the object has a UVW tag, thus delivering weird result.

EDIT : nice demo of the IR going south at the end

John_Do:
The bump channel highlight the issue : when plugged (indirectly here ) to the bump channel, the Triplanar is bypassed and the bitmap use the object UVs, thus making the Triplanar useless with the bump.

John_Do:
Hi,

The bug still occurs in the latest dailybuild ( v13 from December, 9), Triplanar is ignored when the input is a Corona Bitmap.



Also the bump seems to be incorrectly oriented with the Triplanar mapping, but I don't know if it is expected or not.
