solved HighlightLayer - Cannot add an uniform after UBO has been created

[TomaszFurca]

When I add Highlight layer to my mesh, then i got error: " Cannot add an uniform after UBO has been created"

PG with error: https://www.babylonjs-playground.com/#TUNZFH#17 -> when you click run next time, then console do not generate errors. When I remove mesh "leatherHelm" then I can open PG without error https://www.babylonjs-playground.com/#TUNZFH#19.

I also get this warning for https://www.babylonjs-playground.com/#TUNZFH#17

 [.WebGL-0x7fca6486e400]GL ERROR :GL_INVALID_OPERATION : glDrawElements: uniform buffers : buffer or buffer range at index 0 not large enough

and for the next https://www.babylonjs-playground.com/#TUNZFH#19 this warning-

[.WebGL-0x7f9f8684be00]RENDER WARNING: texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering

On debugging, I found this is happening at in the Mesh.render function(https://github.com/BabylonJS/Babylon.js/blob/e00c2c01cee67363f295a9c996c491a9e213981b/src/Mesh/babylon.mesh.ts#L1603) for "leatherHelm"

 if (this._effectiveMaterial._storeEffectOnSubMeshes) {
                this._effectiveMaterial.bindForSubMesh(world, this, subMesh);
            }

// location is undefined but buffer has some value in UniformBuffer class
var location = this._uniformLocations[uniformName];

 

Not sure if this helpful or not

This has been fixed by https://github.com/BabylonJS/Babylon.js/pull/5349

The effect layers were not compatible with multi materials.

Yes - it works now! Thanks
