Hello BABYLON folks!  
This is my first post here, and first of all let me thank you for this awesome engine!  
I am deeply and truly amazed: Features, Docs, Forum, Community, Youtube channel, Playground, Sandbox, Inspector, Editors for all kinds of stuff. Absolutely mind-blowing. Breathtaking!

After start of my journey back in Mart 1, I finally get stuck. The problem is pretty described in topic title.  
here is my solution so far (if it doesn’t render please drag camera a little)

I guess I can pinpoint the problem to single thing:  
find **index** of instanced mesh to change data in sourcemesh vertex buffer  
thanks in advance

You can use the `registerInstancedBuffer` method instead of handling the vertex buffer data yourself.

That way, you can access the color property of each instance right on the instance mesh itself, making everything easier:
