Hello Guys,
I am trying to follow this thread a bit and you guys have been a great help. I am at the moment developing a marching cubes terrain. I started off with a normal Voxel Minecraft terrain, which worked out perfecly well. It is hard for me to read through the entire thread, so I thought I would post my problem: My terrain engine is supposed to help edit chunks, which worked perfectly well on my blocky version of it. Although now if I click often nothing happens and the chunks appear to be edited only sometimes(only if the colliders have a certain shape). I’ve tried everything I could think of. Subtracting the hit.normal didnt work. Tell me if you need more scripts.
