i am a new zbrush user, and i tried to apply a texture on a model head that i picked up in zbrush. first of all, i imported a PSD template for the model. as i clicked the Projection Master, i used a plane3D with a face texture projected on the head. Heres the problem, when i pick up the texture, the texture didnt apply in the PSD template. why is that, and how am i going to fix this? 
Please someone help me!
Thank u
