How do I pass in a 2nd texture into my shader

I want to pass in a 2nd texture into my fragment shader, how do I do it?

Just add a second uniform for it in the fragment shader, eg:

uniform lowp sampler2D texture;
uniform lowp sampler2D shadowMap;

then in your main code you should be able to just do:

mymesh.shader.texture = someimage
mymesh.shader.shadowMap = someotherimage

OpenGL ES on the iPad should happily support up to 8 textures in a fragment shader (unfortunately no textures in the vertex shader)

Thankyou :slight_smile:
