Hi, I'm having trouble applying a decal over code generated 3D objects(not EE editor objects ). Let me explain what I did ...

- I set the decal to be terrain_only.
decal.terrain_only=true;
(note that applying decals will work if this is false, but what I'm looking for is to get it applied only to terrain type objects)

- then on the created mesh I made an actor using its physics part and assigned it under AG_TERRAIN group.

MeshBase base;
PhysPart phys;
Actor actor;

base.createPhys(mesh); // where mesh refers to the created mesh
phys .createMesh(base);
actor.create (phys).group(AG_TERRAIN) ;

I hope what I explained is clear.

Thanks.

Help is really appreciated to make created mesh as terrain type to enable decal drawing on it. I'm really clueless!!

Thanks.

AG_TERRAIN is only for physics actor, you'll need to use 'SetStencilValue'

Thank you so much its working now as I wanted. its funny sometimes when you work several days trying to find a solution then suddenly a small command popup to solves the whole issue in a second . anyway nothing goes waste this is part of the learning process.

to complete this thread the code should be then .

switch(Renderer())
{
case RM_PREPARE:
{
SetStencilValue(true); // will make the mesh to receive terrain only decal
mesh.draw(MatrixIdentity);

}break;
}

please also reset the value to default state after calling mesh.draw(..); using SetStencilValue();

Sure, thanks again.
