You can sort-of make cavity shader with the vertex paint AO tool, but it doesn’t update in realtime. Below it is on a couple of “matcaps” on a blender sculpt I did recently. The vertex colour is multiplied with the material colours in the material nodes. If only there was some way to update vertex colours in realtime as you sculpt.
Please post your Blend file with the setting of nodes 
Sorry, here’s the blend file (I had to trim off some of the model to keep it under 1 MB) Blender 2.49 recommended.
matcap_vert_ao.blend (958 KB)
Did you paint that or was it automatic?
In vertex paint mode, on the paint menu there’s the option: Self Shadow VCols (AO) which automatically generates fake ambient occlusion on the vertex colours.
Wow, this sure makes things a whole lot more fun! Thanks!
A quick test (a funny “dolphin” underwater shuttle). It will be interesting to test some hdr textures to see if they can resampled down to around 31KB (like the textures used below) and yield the same results.
Thanks for the ZIP, M@dcow!
screen shot?
I cant find it…
it renders fast too 
i tried testing it out too 
Beautiful!
do you have one in higher resolution?
EDIT: I mean this same image in higher resolution.
That is very kind of you. Thank you
Simply Awesome!
Thanks for this!
I figured out how to get the maps to begin with…
In Gimp create a new image. Change the color of the background to whatever color you like.
Then go to “filters > map > map object” Then change the drop down menu from “plane” to sphere, and modify all of the setting to what you would like. (diffuse, and spec, are on the third tab under “material”)
After that just crop to the sphere you have created and give it a try.
Voila!!
I’ve tried this with Blender 2.5, but unfortunately it doesnt work like in 2.49 and I dont know why. The rendered result is much brighter and not so satured like the 2.49 render image.
changed the light, changed material color but did not help anything
heres a screenshot:
did you make it in 2.49 and then try and import it?
Try deactivating “Color Management” (Render context in Properties editor)
@Pillum
Try removing the lighting or making the material Shadeless. The lighting and shading are already in the material.
@all
thanks for the fast answers
@Eclectiel
thanks for the right answer
removing light or making the material Shadeless did not help, but removing Color Management did!
just had to put the light energy a little higher after that, but it helped thanks
This is great news, I have always been a sucker for the zbrush materials.
Good work! guess it won’t take long until someone have chopped all the materials from zbrush
Edit: made an image in photoshop, easy way to waste time, when you start you sucks in to it, in 20min I made like 15 materials. good, becauseits realy easy to paint the kind of material you need. can be good sometimes

Free to use to whatever you want.
