NYCdotNet Posted November 9, 2016 Share Posted November 9, 2016 Greetings, I want to improve the documentation for using MultiMaterial and subMeshes. In order to attempt to understand it myself, I put together this playground which I think has everything required to demonstrate the basic concepts fairly well. http://babylonjs-playground.com/#1GRJLM#1 I need help with two things. The first is understanding the difference between vertices and indices. I know the vertices represent the actual points in 3d space - where do the indices come in to play? I'm assuming it's the grouping of the points into triangles, right? Sorry if this is discussed in many places already - I'm having a hard time searching for this stuff. Does the "Index array" section of this article apply? https://en.wikipedia.org/wiki/Triangle_mesh Second, when would you NOT specify 0 and the total count of vertices in the mesh for the second and third arguments when constructing a submesh? All of the answers to the above will go into a docs PR that I'll try to cross-reference liberally. Thank you!!! Wingnut 1 Quote Link to comment Share on other sites More sharing options...
