Title: Normal Shader broken. Hotfix 2, V3 C4D
Post by: davetwo on 2019-04-05, 09:48:22

I am updating a project i built last year:

In the Bump channel I had a normal map (from Poliigon) inserted via the Corona Normal shader and scaled via the projector shader.
Everything worked fine. But when I have come to update the project and re-build the material it's not working properly.
The normal map looks inverted and the projector is not effecting the scaling.

If I remove the normal texture from the corona normal shader and plug it directly into the bump map via the projector, everything works as normal. So it seems to be a fault with the Corona Normal shader.

See screengrab for clarification. Any idea of a fix? Or is the Corona Normal shader now redundant?

Hi, you might need to flip the Y (green) in the Corona normal shader. ? Can you share the normal map?

Has there been a change to how Norma maps work?
It didn't need be flipped previously. Also, this doesn't explain the sudden non-compatibility with the projector shader.
Normal map attached nevertheless
