solved Is it possible to both cast and recive shadows without self shadowing?

[JonVarner]

I have a situation where I have three meshes: "A, B, C". What I would like to do is have mesh "A" cast a shadow on mesh "B" and meshes "A and B" to cast shadow on mesh "C". But I do not want mesh "B" to cast shadows on itself. What I have so far:

window.shadowGenerator = new BABYLON.ShadowGenerator(512, light, true,true);
window.shadowGenerator.getShadowMap().renderList.push(window.mesh_A);
window.mesh_B.receiveShadows = true;

So yes this is possible but a bit tricky

You may need to create multiple lights and shadow generators. light #1 would be from A to B for instance (and thus you will add A to the shadowgenerator but exclude it from the lith with light.addExcludedMesh), etc...

Thanks Deltakosh, that was the ticket. For those who might run into a similar situation here is what I came up with.

light2.excludedMeshes.push(mesh_A,mesh_B);

shadowGenerator = new BABYLON.ShadowGenerator(1024, light1, true,true);
shadowGenerator.getShadowMap().renderList.push(window.mesh_A);
mesh_B.receiveShadows = true;    

var shadowGenerator2 = new BABYLON.ShadowGenerator(1024, light2);                  
var shadowGenerator2.getShadowMap().renderList.push(mesh_A,mesh_B);
mesh_C.receiveShadows = true;
