Substance Painter 2 to Unity 5 Normal Map issues

mark lautenbach

I'm relatively new to Substance Painter 2 and am experiencing some normal exporting issues. When exporting textures from Substance for use in Unity 5, some surfaces appear to be concave, instead of flat.



When exporting the original FBX from maya, all edges are smooth. Substance counters the smooth edges when it bakes, so this shouldn't be a problem. But it looks like Unity is doubling up on the countered normal and bowing the surface in the opposite direction (bowing concave instead of flat or convex).

This problem just popped up and I'm not sure what I did/didn't do to cause this distortion.

Please help.

Hello - you'll probably find a lot of pointers in this thread.

I would check first that you triangulated your mesh before bringing it into Substance Painter and Unity.

Triangulated: Check

I took a look at the thread pior suggested and didn't find anything addressing this specific issue.
I'll be trying out all the things today and see if I can crack it (basically searching for that check box that will make everything work right)

You probably already tried that, but you never know.. Did you try inverting the green channel?

Like Jerc is mentioning, what normal map format did you use in your project ? And which export preset did you choose ? If you used a DirectX normal map, it won't work in Unity as it requires an OpenGL map.

Mark, can you provide us an update? What you've tried, and the results of those attempts? Open GL didn't fix the issue?

Thank you, Jerc!

I swear, I tried switching between DirectX and OpenGL several times, but I must have done something wrong along the way. Upon your advice I tried it again, just in case and BAM!, good to go.

I was about to lose it, so thanks again. I knew I could count on you guys.
