Hello! I have been using anim8or for several years now, and even completed a movie using it some years ago (used to be on youtube but I have since taken it off as it is not the best I could have done.)
Currently, I am in the process of making another movie of sorts, and well, I have had this issue with many of my meshes, often it pops up on cylinders, or spheres where I have "regrouped" part of it in Milkshape 3D to apply one texture to one part, and another texture to another part.
The result is usually these "lines" acrossed the actual mesh lines. Currently im working with a certain sci fi monster, and it has a particular smoothness to its head obviously... Welll, some rather UGLY lines are appearing while im trying to take a look at the texture (and thusly work on bump maps/spec maps). I've tried subdivision, i've even tried joining the solids, nothing seems to work, and it only appears like this in anim8or:
Thanks in advanced guys!
