Title: Normal shading bug with Render Instances
Post by: John_Do on 2025-06-25, 16:18:08
I've just stumbled upon this weird "bug", I don't know how I didn't notice it sooner.

The 3d model of the wall is from Quixel, no displacement, just a normal map.

IR - Instance : correct result

IR - Render Instance : weird shading

Prod - Render Instance : weird shading, like a blend between both results.
