Problems with normal map in Unity5

HolzstockG

Hello there!

I've made KA-BAR Knife high and low poly variants. After that I textured low poly version and baked normal map in Substance Painter 2. I have chosen to bake normal map for OpenGL. In Blender in Cycles Render engine it works perfectly however in Unity it looks not good. Yes it is triangulated.

This is from Blender Cycles Render


This is from Unity5


Thank you for help in advance!

Mismatching triangulation between baking and blender, and/or unity. Damn, there are so much of this here nowadays. Make sure you triangulate the mesh before baking and export. If you export a quad mesh, its very possibly that any of these softwares will triangulate it differently. This is a problem because triangulation affects lowpoly shading, and therefore the baked normal information.

That step-by-step tutorial you followed actually goes through the process and importance of pre-baking triangulation.

HolzstockG

It is triangulated.

Ok. Just to assure us, please triangulate the mesh in blender, make an export and a new bake. Import the mesh into Unity and see if the error is still there. The error shown on the picture is obvious, this triangulation error always shows as a dark "X" in the shading, which you have on the screenshot.

But as I said it is triangulated 

.Wiki

Meshes are always triangulated. But the triangulation can change depending on the application. So its a good practice to triangulate manually before baking.

Have you exported your substance maps with the unity pbr preset?

HolzstockG

Yes I set in Substance Painter template for Unity.

Ok party people I think I have repaired it but I will write about it later I need to go to sleep. Peace!

Blender bakes in OpenGL. Unity uses OpenGL. Sub Painter defaults to DirectX. Was it just a simple swizzle flip?

The problem was I set model to triangalize but I didn't apply it. I thought it works excactly the same like exporting to OBJ file where modifiers are applied automatically but with FBX it didn't work like that... so remember this 'cause I lost 2 days because of it ;_; xD Now everything should work as it should.

There is an option in .FBX to triangulate on export. That was the giveaway....... .FBX to UE4 respects 3dsMax's modifiers but not Blender's, it seems.

Why so sad, Kristof? You were 100% right first time......
