Again new BRTECH1 Engine while-in-development-demostration video

It uses Uniform Shadow Maps (USM, if one player is in current view) and Extended Perspective Shadow Maps (XPSM, if more than one players are in current view) together with Variance Shadow Mapping (VSM) and only with one shadow map FBO texture since it's targeted for mobile devices with limited video RAM size also, where Cascaded Shadow Mapping (CSM) wouldn't be applicable here.

And the first person is attached to the approximately eye position of the each head MD3 model part of the each current loaded player model now.

The next todo-steps will be: Networking, weapon shot physics, game menu UI, and such other things.
