I was so happy when I found out that OIT is merged into the alpha release. Now, I need some help to understand how to use it.
mat.alphaMode = BABYLON.Engine.ALPHA_LAYER_ACCUMULATE;
for a material with mat.alpha=0.8, the result is opaque meshes.
Adding this makes all objects disappear:
scene.useOrderIndependentTransparency = true;
What else do I need?
