Multi material on a cylinder

[EJanuszewski]

Hi all,

I'm currently going through Temechon's book, which I must say is very good, however at the point of playing around with multimaterials I seem to be pulling my hair out, here is a link to a playground I put together http://playground.babylonjs.com/#1K3BTQ, I looked at DK's tutorial on MSDN ( http://blogs.msdn.com/b/eternalcoding/archive/2013/07/10/babylon-js-using-multi-materials.aspx ) but I'm unsure of where the numbers come from to define the indice parameters 

sphere.subMeshes.push(new BABYLON.SubMesh(0, 0, verticesCount, 0, 900, sphere));sphere.subMeshes.push(new BABYLON.SubMesh(1, 0, verticesCount, 900, 900, sphere));sphere.subMeshes.push(new BABYLON.SubMesh(2, 0, verticesCount, 1800, 2088, sphere));

I don't suppose someone could maybe assist me on this and explain what I'm doing wrong, I'm fairly new to the world of 3D so maybe I'm just misunderstanding how it's meant to work.

Thanks,

Edward

I got it to work by making the numbers int values.

You will also need to sort the vertices etc' : http://playground.babylonjs.com/#1K3BTQ#2 but rounding the number of indices will be the first thing to do :-)

in my backlog :

add per ring cylinder uvs and colors feature

Than's for the replies everyone, that's awesome, seems I picked the worst mesh to try learning how to use multimaterials
