Rock WIP
greentooth
Hello,
I was starting to play around rocks. I always had problems with them, so i thought i'd test new technique (new to me, that is).
It has 2k tris, and texturing is stil WIP.
I do have a little problems with panting texture though.
I'm trying to paint some "highlights" where the sharp edges are, and i'm using normal map as base for that, but, it's a bit hard to see what is up and what is down, so i sometimes paint where it isn't sharp edge, but is whole.
Any hints how to aproach this?

Have you tried baking a curvature map?
If you have Xnormal installed then use the Photshop pluging that it comes with. It allows you to create a cavity map out of your normal, similarily to Crazybump.
If you don't want to use either of those, you can use a very dirty hack to get similar results. Simply load up your normal map into Photshop, desaturate it, use the highpass filter on it and then adjust the levels to bring out the highlights. It may not give you the correct results, but sometimes it does the job.
On a side note, I would probably go back into your sclupting app and define the planes of your rock sculpt a bit more. Right now, some of the surfaces look a bit "blobby". What tool are you using? Both Mudbox and Zbrush have some brushes that make sculpting hardsurface objects very easy.
Crazybump idea sounds very intresting, i will try it.
I also do have Xnormal, in fact, i used it to generate normal an AO maps.
I used ZB, mostly trim dynamic and trim Adaptive, and claytubes here and there.
But yeah, you may be right, some areas do look a bit too blooby.
Tnx for the help!
Don't be afraid to use the smooth brush; all you need is to smooth slightly away from the edges. Perna had posted a really cool minitut on his site.
My first from scratch model was a rock, and I failed pretty hard so im interested in where this will go.
I second this, and think it's more or less exactly what you were looking for. Be sure when generating the cavity map to set the method to EMB (emboss) and then blend it with overlay.
Anyway, tried to change color a bit, make it less noisy, is this any better?
