reconstruct a subdiv layer from normal
show user profile  Mr_Stabby
I wanted to re-detail some areas on one of my characters but it seems I managed to destroy the mudbox project. All I got left is the source cage and the 4k 16bpc normal map. Now, I know that normal maps are applied as strictly shading effects but given that I know how the mesh shades without the normal and with the normal, it should be possible to extract a displacement map out of it. Anybody been down this path before?

You can extract the height map from the normal using a Photoshop plug in but I think the actual displacement information just isn't available in your normal's.

Hope I'm wrong - Good Luck

edit: 'X Normal' may have something useful in area as well but its been years since I've used it.

Yea I tried extracting a heightmap but its just not the same :/ I sorta get the same shapes but the amplitude is just way off. Meanwhile I started from scratch with the bumped mesh as a reference, its going pretty quick this time, I'm half way done.

As Campbell said, don't think displacement is going to be possible.

If you have your diffuse and normals you can get good selections, though, and create a displacement. I'd use colour select and create masks and stuff. Will be tricky though.

Just as I went to extract normals from the new details I made, I noticed a new button in mudbox - "Sculpt using map" that does exactly what I wanted... derp lol. Well the new stuff is much better anyways...
