[Next] [UDMF] Scrolling planes + Slopes + Texture Scaling cause rendering problems in software
This just seems like an issue with how texture scaling works on slopes in general, however, its the most prevalent on scrolling planes, as after a while the texture visually stops scrolling, it determines on the scale of the texture and speed of the plan, the closer to 0 it is (the bigger it is) the faster this happens, though the smaller it is, the longer it takes for it to happen. This is mainly a problem when the texture is scaled bigger than smaller however, as making the texture scale by half the texture size takes way too long for the visual issue to occur.
This can do more than cause it to visually stop, it can also make the texture corrupt the scaling. While I couldnt reproduce it in the control map, it did happen in the skybox of one of my maps im converting to UDMF. Contains the control map with just the sloped scrolling plane with a texture with a scale of 0.25, which causes it to break at 15 seconds in.
