I’ve been working on a different project but it also uses a lot of techniques from this part of the course including normal maps. I have a wall texture I’d like to use as a normal map but it isn’t behaving as I’d expect. Specifically, shadows and highlights not appearing in the expected places based on the lighting, and some surfaces where I’ve applied the normal map appearing as indentations rather than raised bumps as I modelled.
Here the close side of the cube shows the texture from the normal map as I’d expect, but the top surface appears to be indented.
I also made a couple of animations with a light source moving around the cube which somehow don’t appear right:
I’ve spent a bit of time rotating the normal map, increasing the thickness of the shapes in my model and then re-baking. Feel like there is some fundamental element I’m missing here. Any ideas?
