Recently, an awesome feature has been introduced - Custom Instance Buffers - Use Instances - Babylon.js Documentation.
I’ve successfully tested it with manipulating ‘color’ attribute. It looks like this attribute colour is being an additive colour to the main vertex colour, that’s why it’s alpha value has no effect on resulting instance transparency.
Now I’m wondering is it possible to use custom buffers to control instance transparency?
I have a weak knowledge of shaders and don’t know at what level material
alpha property is being applied. Is it being sent as an attribute to vertex shader?
