I am working on map generator for my project. It generates maps like this on enterpress.
Randomization use cos function to generate realistic hill and waleys terain. So far it includes two materials which are attached to matrix tilles bye their height, totaly automaticly.



I had problems with texture smoothing and mip maping, it paint lines at borders of tilles:



Thanks to RPGamer I found out hove to use trim command but its not ideal solution so I am trying to make flexible terain using memblock right now.

looks nice although the fog like aura over the images seems to detract from the clarity a bit. still very good work tho.

Thanks
Its because fog distance is related to camera position and skysphere at center of scene so they dont match each other. Thats only for test, in project sky will be adjusted to camera position...

I was making my own program in DB which make transitions between two textures based on monochrome map. Works on the same principle like Wan Trans. If you want something like this I think you can download Wan Trans at WanBs web page.

Then you load it in DB, use prepare matrix texture comand to split it to tilles and then its up to you to ad apropirate map tile to matrix tile. My program do it automaticly acording to height of tile corners.
Hope it helps...

DRAV a legend coder from the early days of DBC had made an open source texture blender. I learnt my concepts from his source ages ago.

Its simple principle: Take RGB walues at the same coordinate of two textures to blend, then take one of the walues (R for example) from reference monochrome map at sad coordinate an calculate percentage of color component. Then divide diference between RGB walues of textures acording to percentage. Repeat for all coordinates.
