Hello, everyone! I downloaded the model of the girl Amy from Mixamo, converted it to obj in Blender, uploaded to Mixamo, and saved the animation needed. Then I imported it to GG classic. It fell through the terrain if it wasn't flat. I changed the collision mode to 3 and it worked.
I did the same with the Mousey model from Mixamo, except I combined multiple animations in Cinema 4d. But the character keeps falling through. I think it has something to do with the collision. When importing, the model is very small compared with the collision box or whatever it's called. Should I do anything with scaling before importing or should I somehow adjust the collision?
