When the scene clearColor is transparent, overlapping with other elements causes color blending

[inteja]

Ah, here’s the answer I think:

Transparent canvas background

This is because by default the canvas is in premultiplied alpha when using webgl. Just run the engine initialization like this: var engine = new BABYLON.Engine(canvas2, true, { premultipliedAlpha: false // Ask for non-premultiplied alpha });
