I have been sculpting a character for a while now. I made some base meshes of teeth in 3D Max 2012. At first I had to use transpose to move them up to the mouth. THen I went to a different file and loaded the teeth into that max file, and exported them from that file to see if that would fix the problem. And if has not.
When using symmetry, if i start in the center all the details start sculpting fine. But as I branch out to the sides of the model, you can see in the picture, the sculpting starts to fade. The only way I was able to get the lines on the left side was to push down REALLY hard on my tablet. But even using just a mouse, it still doesnt even give me my symmetrical lines.
