This question already has an answer here:
I'm new to blender, I started about a week ago. I'm currently designing a human head. As for the details, like lines, little molds etc., I thought of using sculpt mode. So bsc. what I did was, editing my object, or rather it's vertices, make it more "high poly" with a subdivision modifiers, editing again, subdivision again, and so on.
Now I ran into a problem.
When trying to use the sculpt tools, literally nothing happened. i searched the interenet for answers, all I found was the tip to turn on "Dyntopo". I did. After that the sculpting tools had effect, but the effect wasn't the one I wished for, neither the one it should be. It was more like little cracks in my model, I can't even describe it properly, but I'll add images.
Any ideas what I'm doing wrong? What settings should I use? Is there a way to finalize my model, so that the PC doesn'T take it as editable object anymore, in order to improve performance when sculpting? Kind of locking the vertices? I'm running a GTX 980 and an I7 3770K and 16GB RAM, still it lags like hell...
Thank you very much, I hope this is the right place to ask this kind of question!
