I think the overall structures in these rockfaces are great. I love the striations ect, but personally I have found issues
with putting very much small texture / noise in my hi-poly sculpt directly. That stuff I think, with my limited knowledge, can go in the diffuse or as a bump/texture drop ontop of the actual rendered normal map.
I learned how with this tutorial by Ben Mathis;
bottom of the page.
I could easily be wrong here, im noob.
Hey, questions, do you use original alpha brushs in Zbrush that you create yourself? Ive tried it a couple times but ended up worse off than just using the standard brushs.
cool work so far go go go
