A question about Mapping in Maya
So, I've been working with normal maps and (GOD, DO I LOVE THEM) as they can help so much when you want to create a high poly look on a low poly model. But I am having trouble with one thing.... depth! They don't seem to capture depth. Whenever I create, say, a simple cube and then extrude it to have like outward bars on it's sides, the map comes out but the bars are flat, looking more like a 2D image then 3D.
So my question is, can you fix this in some setting on a normal map to capture depth detail? Or do I have to use something else like say a displacement map?
Thanks guys! Appreciate the help.
