Then do it yourself. You can't? Then I guess it IS hard?? -.-'
I would, but my computer sucks. If no one has made it by the time I get my new laptop, then I will. And it really isn't that hard. You make a cube, flatten and stretch it, put a texture on it, export it, and BAM! you have a ramp. The only problem is that Everyone would have to have it for it to work, right?
