I am creating a 3d game, I have the movement and other stuff done all that is needed are maps. Probuilder is a nice tool however I am really bad and slow with it. Making maps is much quicker for me in sketchup however I can’t manage to add colision to it. I changed layers, edited the models, clicked many different options, changed setting but nothing works and there’s hardly any tutorials for using sketchup models in unity, the existing ones only tell you about importing models. Somebody help !!
