david028 Posted March 22, 2016 Share Posted March 22, 2016 Hi, I noticed that the default vertex shader sets gl_Position using: gl_Position = viewProjection * finalWorld * vec4(position, 1.0); Where mat4 finalWorld = world; I am trying to test out some of the default material shader code using CYOS but all I see is a blank output if I use this.. http://babylonjs.com/cyos/#1JYG69 Could someone explain why this works in the default vertex shader but not in CYOS? What is the difference between this and gl_Position = worldViewProjection * vec4(position, 1.0); ? Quote Link to comment Share on other sites More sharing options...
