Light seam on matcap bake (zbrush)

achillesian

This is what I'm doing (after I have a model with subs, a low poly, and uv's)
1. generate displacement map
2. create plane polymesh 3d
3. subdivide a bunch
4. apply displacement map
4.5 Turn off ao and shadows in the render settings
4.8 BPR render
5. grab doc to create texture
6. export texture
7. cry

This is what I'm getting:


As you can see there are little seams of lighting messin WIT MY SHIT? HOW FIX BROS?

Ah, I see the issue, although I'm not too sure why you're rendering it like this.

ZB for the Matcap's uses Sphere-Mapping, meaning the light at a 'view' or 'seam' will always go from a certain color and direction to another, in this Upper Orange to Lower Blue, always facing the camera.

So it's not ideal for baking, I suggest using a flat material, like Basic, or Cavity, although even in those cases you will get issues.

Although I'm confused, can't your simply bake your AO/Disp/etc already from ZB without the need for a Doc Grab, or is there a reason?

Depending on the software you're using, your can create the effect in that software pretty easily.

I want to get the shading and highlights and color variation that a matcap provides into the diffuse.

What matcap is that ? A lot of them are not going too look good once all that info is static.

Check to see if subdivision smoothing is off for the mesh and uvs. Also try a best render instead of bpr

update: ended up just using zapplink, and it's working great
