Sorry, I know my questions must seem really dumb, but despite looking at the video tutorials and other people’s replies to similar questions, I can’t get polypainting to work.
I created a model using a zphere and zsketch, then created a unified skin. I did some additional modelling with brushes to get the shape I wanted and have divided the model into about 390,000 points. I imported an image into spotlight and followed the instructions in the zClass video, but my texture doesn’t paint onto my model. I’ve tried again and again to repeat the process, but nothing seems to work. I am finding it incredibly difficult to follow the process of created a painted model, because each step is separated in the documentation and I don’t know if I’m missing a step.
Can anyone help, please? I know I’m missing something, but I don’t know what. 


I’ll play with append.
i work now on a 7770 hd and 8gb of ram and one 6 six core processor, all go really smoth, but Zbrush only support 4gb but not problems of handle
