Hi there ! Thank you for this little tool, it comes really handy for my workflow ! I justed wanted to ask a little advice, because I don't understand a thing in Blender. :)
So, this is the my building model created from your "SpriteTo3D" tool. I still have to carve all the windows and doors openings, but I noticed that some vertices (these orange dots are vertices, right ?) are already designed at the right places. Is there a way to extrude / delete them all at once ? Instead of re-carving manually with the knife ?
(Sorry for the noob question, haha... I really want to automate or streamline this process as much as possible, and go back to my game engine ^^)
