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.
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.
Thank you for bringing this to our attention.
I can confirm this and will report it to the dev team.
Once again, thank you for the feedback.
Kind regards.
