Normal Map comes out like poop
polycounter lvl 3
So, I did the high poly sculpt, exported that as an OBJ, made my low poly and UV'd it, also exporting it as a .OBJ
When I put everything in xnormal, this comes out:
If it's any help, the high and low poly look like this:
halp plz

Purty simple stuff
also recheck your uv maps and makue sure to break up all hard edges
if you have mirrored pieces make sure to move the mirrored pieces out of UV boundaries when baking this
2. Set your smoothing groups by uv Islands (use a script)
3. Force triangulate your model before you bake.
4. Never modify your low poly model after you bake. If you do, rebake your normal map.
5. Always view your normal map on the model in a game engine, rarely look at the normal map texture and assume errors.
Check the box "Limit Polygon Size" and set the "Max Size" to 3. Export that.
This is called non destructive triangulation and will prevent you from making the triangulation permanent.
We do this because the .obj export will compute how the triangles are arranged differently then other programs and this will de-sync your baked normal map and give you errors.
Also make sure you are using a cage, xNormal has the option to create a cage mesh within the program.
I got frustrated for a while and tried to re do the proccess of unwrapping and exporting a bunch of times, but I'm afraid I might have effed something up...
No, the same location in your 3d program. If they aren't exactly aligned it won't bake properly
Any tips on how to do that in Maya?
