I have an object already created in blender, a tree, or a human, or a pipe.. and I need this to be drilled with multiple holes.
The holes are painted in an image, that is, it is an image that has a repeating an images pattern (they can be circles, squares, or any form).
If you need more information please ask me. Thank you!!
It all depends on how you are going to use the model.
If all you want is an image to be rendered then use the white part of image to control the transparency of the object.
