Matcaps

Matcaps

Postby brektzar » March 4th, 2011, 3:13 am

Have any of you ever tried using matcaps in blender? If you combine it with GLSL in the 3D viewport it looks cool ;P

Plus its speedy renders and small textures for a rather nice looking result :P

Basically its a texture :P
You could probably say its a miniature HDRI :P Zbrush uses these, you dont need any lighting for them, theres more stuff to it than just that though :P BUT, heres how you apply them:

First, go here: http://www.box.net/shared/fo74kz8mkm#/s ... 1/35890754
Find a matcap you want, download it.

When in blender, load it up as any normal texture, but set it to go along the normals(not in the influence section, the mapping section!)

Press shadeless on the material, enable GLSL and watch your object with a nice material :P This also speeds up rendering times, since theres no lighting theres no real shadows and so on.. you get it? xD

For the best result you should add AO though.

Matcaps are great! They are especially great for sculpting in Dynamic Topology! It's a shame that you can't render them though :/

I love using matcaps! I often use them to add a quick preview material to my models, in which I can see if everything is going to look right :D

Yeah, matcaps are awesome. There was a way to render them too, i just cant remember how, it could have something to do with reflection :S

You can render them if you make them yourself, because when you make them yourself, you have to make them as a material, so it can render, if you get what I mean :P

A matcap is just an image mapped to the object's normals, so there's no need to recreate the material. That image contains all the lighting, reflections, and whatnot in it. The spherical image you see in the preview in Blender is just a smaller version of the actual image used.

Blender Docs: http://wiki.blender.org/index.php/Dev:R ... D_viewport
Ben Simonds shows how you can make those images, including a few you can use (give proper credit!): http://bensimonds.com/2010/07/30/matcap-generator/

Another option is to clean up the viewport and take a screenshot. I did this in the wireframe tutorial (step 6) a couple months ago, matcap "render" on the right:
