Hi,

I'm using the latest daily for a project and encounter for the thousand time various bug and inconsistencies with the bump channel.

Errors found in my current scene :

• Bump doesn't work with Render Instances in IR ( took me 10 minutes to find why the bump wasn't appearing )
• Corona Bitmap > Corona Color Correct > Bump = Color Correct doesn't work as expected, for example setting the curve flat from one end to the other makes no difference. Contrast doesn't work. Brightness works.
• Corona Bitmap > Filter = doesn't work
• Bitmap / Corona Bitmap > Mapping Randomizer = bump breaks if there is another material tag on the object ( and only bump, basecolor if fine ).

And these are not the only ones, there are also issues with Triplanar and Layer shaders to fix.

Bump is a critical feature, could you guys fix these once and for all in the upcoming release ? It's been at least FOUR years that some of these are reported and since this time they're living a long and happy life inside our beloved render engine.

Thanks,

Yup, preparing maps as best as possible, or editing on the fly (3rd party app) and excluding use of Corona Bitmap & CC is still advisable for more Effortless workflow™. (Bump and "Filter" work w/o those - on top layer).

I feel that the Corona Bitmap node needs an urgent update in general. There are several threads on this forum noting its various shortcomings.
