That's really wacky... the texture even changes frames to match the Mario sprite in the center. 3D Boxes aren't even supposed to be able to have animated textures
When you rotate the Mario sprite off-screen, the texture corrects itself. And aren't your boxes supposed to be green on top?
Okay, I've finally gotten around to testing some things out. I can open my project now, which is good... but the platform movement is still broken, which is bad.
It's not as broken as before (seeing as how it actually loads now), but there are problems, mainly with the jumping. I tried it out on a fresh .cap and it's doing the same thing... if you jump while standing still then the sprite makes a puny little jump that gets cut off too soon. If you jump while you're moving left or right, it jumps to it's normal height. And when it hits the ground after a jump or a fall, it jerks to a stop for a fraction of a second and loses all horizontal momentum. Hitting a ceiling also makes it lose momentum.
The sprite also sticks to walls, and jumping against a wall will cut the jump short the same as jumping into a ceiling.
The new gravity directions also don't work properly. The sprite gets stuck in the air when you jump, or sticks to ceilings and walls, until you press one of the left/right movement keys.
