What are all the babylon possible shader attributes and uniforms: // Attributes attribute vec3 position; attribute vec3 normal; attribute vec2 uv; // Uniforms uniform mat4 worldViewProjection; i assume they will all be equiv to some webgl attribute (if you had to do in strait webgl).  So i assume: position = gl_Vertex -> To vec3 normal = gl_Normal -> To vec3 uv = gl_MultiTexCoord0 - To vec2 and  worldViewProjection = gl_ProjectionMatrix * gl_ModelViewM
