I am having a frustrating time with Poser 4 on my Mac. When I go to render a picture(simple or elaborate) I get messages that it can find or read textures(even when everything is in its proper place), can't render shadow maps and my favorite, not enough memory(I gave it the 62464k in the minimum and preferred, I have 40GB on my hard drive). Sometimes the program just shuts off after I get these messages. Am I missing something? Doing something wrong? Please help.
