I need help again.
I use DARK GDK, BTerrain and VC++ 2010.
DBPro code terrain multitexturing work fine:
TerrainObjectID = 1
load image "images/rock4s.png", 2 ` low altitude
load image "images/grass1s.png", 1 ` medium altitude
load image "images/snows.png", 3 ` high altitude
load image "tropicalrgb.tga", 4 ` steep slopes
texture object 1, 0, 1
texture object 1, 1, 2
texture object 1, 2, 3
texture object 1, 3, 4
load effect "terrainFXv2.fx", 1,0,0
set object effect 1, 1
In VC++ this code work fine too:
dbCreateObjectPlane ( 1000, 1000, 1, 90000);
dbTextureObject ( 90000,TERRA_DEATIL_LOW, 0,0);
dbTextureObject ( 90000,TERRA_DEATIL_ME,1,0);
dbTextureObject ( 90000,TERRA_DEATIL_HI,2,0);
dbTextureObject ( 90000,TERRA_COLOR_TEXTURE,3,0);
dbLoadEffect("Resource/FX/terrainFXv2.fx",0,0,TerrainFX );
dbSetObjectEffect(90000, TerrainFX);
In VC++ this code make BLACK terrain
:
BT_BuildTerrain(TerrainID,TERRAIN_MODEL,1);
dbTextureObject ( TERRAIN_MODEL,TERRA_DEATIL_LOW, 0);
dbTextureObject ( TERRAIN_MODEL,TERRA_DEATIL_ME,1);
dbTextureObject ( TERRAIN_MODEL,TERRA_DEATIL_HI,2);
dbTextureObject ( TERRAIN_MODEL,TERRA_COLOR_TEXTURE,3);
dbLoadEffect("Resource/FX/terrainFXv2.fx",0,0,TerrainFX );
dbSetObjectEffect(TERRAIN_MODEL, TerrainFX);
BT Terrain dont support shaders in DarkGDK?
ps. shader code:
// Green Gandalf's Terrain Shader v2.0
// blends three images together using a fourth texture
// to give a detailed terrain
// Created 12 October 2006, modified 18 January 2007.

zzz!
