yep, prissi, and that's what I already implemented. the problem comes from the situation uploading the textures each frame consumes too much CPU and PCI bandwidth, so I have to create a texture with all possible tiles and upload it first, and re-use it on all frames. To make this I added some code to calc_water_level anf just uploaded all those images.
This has already been implemented and it works perfect, boosting performance.
the problem is now i want to do the same with slopes and ways, and can't see a good place in code to locate wich are those images. about slopes i was thinking generating them from textures prograatically like climate tilles are now, and do the code for simutrans 2D too, auporting doble heigjt. but how to register just way images?
