I’m going through Blender Cookie’s “Creating a 3D Typography Effect in Blender” tutorial, and I’m having some real issues with the initial boolean modifier step. I create the text, convert it to a mesh, clean it up, and position it. Then I select the cube, apply a boolean modifier, choose one of the mesh numbers, then switch it to “Difference” just like in the tutorial. Sometimes it cuts the number out of the front of the cube, other times it just cuts random pieces out, other times the entire cube disappears leaving just the number.
I have no idea why it only seems to work sometimes and not others, even when I follow the exact same steps as in the tutorial. Is there anything in particular I should be looking for?
