MaterialMapping multiple textures to a one material?

by Caylo Gypsyblood · in Torque Game Engine Advanced · 03/04/2009 (5:29 pm) · 4 replies 

new Material( TerrainRocks )
{
   FootstepSoundId = 1;       // Hard footstep sound defined on player datablock.
   ImpactSoundId = 1;         // Hard impact sound.
   ShowDust = true;           // Show dust particles.
   ShowFootprints = false;     // And show footprints.
};
 
addMaterialMapping( "cliffsnowrock1"           ,  "material: TerrainRocks"  ); 
addMaterialMapping( "Clifficyrock"         ,  "material: TerrainRocks"  ); 
addMaterialMapping( "Cliffsnowrock2"           ,  "material: TerrainRocks"  );

I dont understand why this is not working. From everything i read about MaterialMapping it should work.

The is from the DOC file who ship with TGEA:
Quote:
You cannot map multiple materials to the same texture tag. You can, however, map the same Material to multiple texture tags. To do so, use the addMaterialMapping script call as follows:

addMaterialMapping("grate", "material: Grate");
addMaterialMapping("grate2", "material: Grate");

What i think is saying one may map multiple texture names( texture file names right? like a mapto= entry?) to a material. And it do not seem to be working, so im gunna call it a bug or bad DOC's.

It was a bug, find ConsoleFunction( addMaterialMapping and replace:
ConsoleFunction( addMaterialMapping, void, 3, 3, "(string matName) Set up a material to texture mapping.")
{
   MaterialManager::get()->mapMaterial(argv[1],argv[2]);
   Con::warnf(ConsoleLogEntry::General, "addMaterialMapping= texture:%s material:%s", argv[1],argv[2]);
}

Now works as expected...

Humm... does this come up often? I mean the need to have the same material mapped to several different mapTo names?

If so maybe we should make this work...

new Material( TerrainRocks )
{
   mapTo = "cliffsnowrock1;Clifficyrock;Cliffsnowrock2";
 
   // etc.
};

mapTo = "cliffsnowrock1;Clifficyrock;Cliffsnowrock2";
 would be most convenient.

I have many foliage, bark, cement, wood, terrain- ect types of material who only differ in the actual texture. For terrain textures alone, its nice to setup Material by an generic type like:
new Material( TerrainMud  )
{
bumpTex[0] = "Dirtballs_norm";
 FootstepSoundId = 1;  
 ImpactSoundId = 1;       
 ShowDust = false;        
 ShowFootprints = true;    
 friction = 12.0;
};
and as of right now, i simply addMaterialMapping all my 'mud' textures to the TerrainMud Material. I even use the generic TerrainMud Material on DTS and saves me the time of building new Material every time i use a different type of mud texture.

addMaterialMapping and Material inheritance ( new Material( NewSlightlyDifferent : AlredyBuiltGeneric ) have become a few of my favorite new friends.
