This probably was valid for old terrain system. In new terrain, 'base material' default shader uses splat map (and it is one of the visible materials from close distance). In terraindemo from new terrain branch the base material is lava (you can see it on top of volcano), check this screenshot: http://img143.imageshack.us/img143/1504/terrainsplat5pk.jpg the base shader: <technique priority="100"> <tag>terrain_splatting</tag> <pass> <mixmode> <copy /> </mixmode> <buffer source="texture coordinate 0" destination="texture coordinate 0" /> <vp plugin="glcg" file="/data/terraini/geomorph.cgvp" /> <texture destination="unit 0" name="tex diffuse" /> <texture destination="unit 1" name="splat alpha map" /> <fp plugin="glfixed"> <fixedfp> <layer> <colorsource num="0" source="primary color" modifier="color" /> <colorsource num="1" source="texture" modifier="color" /> <coloroperation operation="modulate" /> </layer> <layer> <colorsource num="0" source="previous layer" modifier="color" /> <colorsource num="1" source="texture" modifier="color" /> <coloroperation operation="modulate" /> <alphasource num="0" source="texture" modifier="color" /> <alphaoperation operation="replace" /> </layer> </fixedfp> </fp> </pass> </technique> unlike to old system I don't see any reference to LOD. Could someone explain me how it should work? -- greetings, Piotr Obrzut mailto:[EMAIL PROTECTED] ------------------------------------------------------------------------- Take Surveys. Earn Cash.
