Question

` I’m trying to recreate a shader I made in blender, I need the vector of the camera to the mesh to do that but I don’t know how to type it/code to use. Googling around I found some suggestions but they create a static definition, I need one that updates every frame. The blender definition of the function im trying to recreate is ‘Vector pointing towards the point the shading point is being viewed from.’.

// NORMAL 	// surface normals in view space
// VIEW		// cmera view in view space already normalised
