Hi yukio, The short answer is no gem does not do booleans, though there maybe some work arounds. I wont try to talk you out of booleaning as a dirty modelling practice, but instead will tell you that gem is better as an animation tool. Therefore, I suggest that you created some lowpoly models (my preference is using Maya), and then import them into gem as .obj files using the [model] object. Does anyone have experience with importing object textures in gem for there obj's? It would save a lot of time over texturing with [pix_image].
