Little problem with your
rock Ron , you used a frog leather texture material , that is were it isnt hand painted .
The handpaint is a technic where you dont use any kind of pre made texture , you paint all on your own ( you can of course use effects like dirt or edge wears ) .
And i realy dont see the link between my
rock and the 3Dmotive pipeline , 50 % of mine was different of what you described ( they use ndo , i use substance painter and zbrush ).
Also watchout for your
rock , the texture you made with the frog leather dont give the "
rock" effect to your
rock. By that i mean , did you use refferences ? What kind of
rock do you try to achieve ?.
Hope you will post your
rocks on your own thread so we can see your updates , it kinda floods the lisibility of mine if you understand what i mean
