non at moment but, I think i know how to make em, i got alot time to mess around, like i did on Desert Ramps, those also one of a kind for new ramps.
but it gonna cost money for these ramps.
I made LGI Manibus space inverted ramps but he paid in full.
Think twilight ramps might be little on ugly side like space inverted ramps are, it take some time to get right tiles to make it good, not shure never tried it.
think it is, better to just grab 1, or 2 tiles from ramp itself to add
u cant take tiles from the original ramps b/c there are no tiles that blend the 2 grounds any way to make it inverted. i dont know how to go on from there.. if there is a way to make it unbuildable i wuld do it.. perhaps find a way to make a new tile :)
If theres a tile in there i can find the bugger, thats how i figured out desert ramps, I couldnt take ramp tile to finish transition, I had to make ground foundation first then put tiles down.
Im shure there a way to do something with twilight, I play around if I get in mood, but right now im juggling 3 maps I havent finished.
