Irrlicht Engine

I made one big city territory mesh and when i textured it and imorted it in irrlicht i have seperadly textures areas in different Z values. I mean some things are higher and some things are lower. When i apply only one texture to all mesh then the mesh is ok again. But when i try to put on different textures the mesh is broken. Sometimes its ok but most of the times different textures on one 3ds mesh file are screwing my mesh.

What am i doing wrong????

my 3ds format displays fine, but i use sketchup google, hybrid would be the person to ask, he programmed 3ds loader

Show some screenshot and probably also provide the mesh for some tests. It's often a problem with wrong UV mapping.

thank you hybrid. I think its something to do uwp mapping aswell. But how can u use uwp map right? without uwp map when you load game textures into engine they are big and ugly so i had to use uwp map to make them smaller so they look prettier on the mesh. I provide with my test file. I have script too you might want to look into that. Its the first tutorial redone to load my mesh. I have mesh file too and i put some random texuter into it. if u look mesh in 3dmax it looks fine but when u load it into engine its becomes broken.

Any good suggestions how to use UWP mapping correctly is welcome because i want to model level and i want to texture that level in 3dmax and i want to import them into engine. I know that you can apply texture to mesh trough source code but its too much coding for me. Texturing mesh is easyer in application.


Thank you for your time.
