It's a little hard to say without looking at the project file, but it looks like you're using a material or materials in the sketch effect's hidden line link box. If you have a material in there then it will render hidden lines, depending on how you have your culling settings arranged. It can get quite complicated if you have a bunch of sketch style tags.
I added 1 texture to a null that have all the other objects. Also, i did the toonish by selecting it on the render settings. Can you explain me step by step what do i have to do to fix this? i tried everything, including "line" options. I guess adding the texture to each part of the 3D shapes won't work, because i tried. Weird thing,i worked with this cartoonigh style before and this didn't happen.
Hello, i found the solution about this problem. I was using native shapes, not transforming them into customizable objects. When i converted them (clicking C on keyboard by selecting them)i figured out the solution. Lines weren't reaching on top anymore.
Anyways, thanks a lot. I been using this sketch/cartoon style for a little time but now i guess i can handle this situation without any inconvenience.
