Anyone know of any examples of how to create a field with varis textures, for example boiling, stones, mud, roads etc.. A greeting.

Did you mean: Terrain with multiple different textures? Then check this one for examples on "Texture Splatting": here(link) Also see my earlier post: here(link) Especially the "Insaner" demo should be usefull (look in your Blitz directory at: "samples/mak/insaner" And of course: here(link)

If you don't need each texture to blend with each other, you can simply apply different textures to different polygons in your modeller application. When you export your mesh to the Blitz3D format, the exporter plugin should break the model into one surface per texture. An example of how this may look can be seen in N64 games: The parts with transitions are just textures of the same size that are stretched - making them lose sharpness in relation to the other texures. A way to address this is to use another texture layer that is tiled and 'multiplied' on top of this stretched texture, or just use a bigger texture for this. They also make extensive use of vertex colouring to add variation and convey lighting, though if you can combine this with the use of lightmaps (with Gile[s], for example), the result is much better.

Hello, much appreciate the intention of trying to help me, I always have something new to learn, but there is a simple example?, that for me I do not speak English very easier to understand, excellent capture Kryzon, something I understand in order to make . A greeting.

[EDIT: wrong link, added bits of code] Ah, Krishan's Mesh Terrain. He has the same thing right here actually: http://www.blitzbasic.com/codearcs/codearcs.php?code=2620 It's very nice, but depends on what you want to use: standard Blitz Terrains or Mesh Terrains. Blitz terrains: easier to manage(build in LOD etc), but also some restrictions. Mesh terrains: more flexible, but harder to manage(you have to write your own code or perhaps use Krishan's above code(or better use his BlitzTiles, see here: http://www.blitzbasic.com/Community/posts.php?topic=84809#1130807 I personally use Blitz Terrains cos it's easy to use and let's me deform the terrain for craters when I throw grenades. :-) I used a modeler to create the terrain and paint different textures on the terrain(roads, rock, grass, sand etc). Then save it as one huge texture and export the heightmap. Then in Blitz it loads the Terrain Heightmap, Terrain Texture and a 2nd texture for detail in close up. Last it also loads one for lights, shadows and burnmarks. You can add another texture layer too, but I didn't see the need for that. For example: Terrain=LoadTerrain( "HeightMap_512x512.png" ) ScaleEntity Terrain,8,200,8 ; make Terrain 4096x4096 wide and heightx200 units. EntityFX Terrain,1 ; Textures land_tex=LoadTexture( "HeightMapTexture_4096x4096.png" ) ScaleTexture land_tex,512,512 tex0=LoadTexture( "DetailTexture_512x512.png" ) ; detail texture for closeup ScaleTexture tex0,2,2 tex1=LoadTexture( "LightMapTexture_256x256.bmp" ) ; lightmap ScaleTexture tex3,256,256 EntityTexture Terrain,land_tex,0,0 ; original terrain EntityTexture Terrain,tex0,0,1 ; detail texture EntityTexture Terrain,tex1,0,3 ; lightmap TerrainDetail Terrain,8000,True ; if set to 1000 then weird fx TerrainShading Terrain,True ;set up picking - cos shooting and stair climbing needs pickable geometry. also usable for other stuff too EntityPickMode Terrain,2 EntityType Terrain,type_world I used the Insaner Demo as a template for this.
