Or use the "layout syntax" in the shader itself, so you can skip setting the
"value" ("texture unit selector") of the uniforms (like you do above), like so:
>> layout (binding = 0) uniform sampler2D foo;
>> layout (binding = 1) uniform sampler2D bar;
>> etc.
Works at least with recent OpenGL versions (and off course only if you write
the shaders yourself ;)).
But by now I realise that the "SG" prefix probably stands for "Scene Graph"
(which you are probably extending with your own objects), so you're with OpenGL
ES 2 I guess (which probably won't digest above shader "layout" syntax).
Cheers,
