I've sent a set to RGUS, but not these. These are all 100% self-made maps and I'll make a tutorial for how to make them later on. Just not now, I'm fucking knackered at the moment.
The background for each image is what the HDR map actually looks like. The system for making them is actually stupid level simple and assuredly idiot proof. And I know, when it comes to 3d I'm a complete idiot.
