I just check “visualize pieces” for the screenshot, but it didn't work even if I uncheck it
And yes I'm sure my object have UV because I import the same object without any destruction steps and the shader is good (check my screenshot)
I don't understand the problem with have the DOP network at OBJ level ? Is not the automatic way to do ? In my tutorial, the tutor have a “dop network” in the same level to all his destruction steps, in his geometry level. Is it the good way to do ?
