More 3D Improvements -=-=-=-=-=-=-=-=-=-= -Sprite3D and AnimatedSprite3D support. -Opaque pre-pass works, is compatible with shadows -Improved shadow map rendering (can differentiate between plain opaque and opaque with shaders/discard/etc) -Added option to use alpha discard in FixedMaterial -Improved Glow FX, many more options (three modes, Additive, Screen and SoftLight), strength and scale -Ability for Background (image or cubemap) to send to glow buffer -Dumb Deploy of clients now actually works in Android -Many Many rendering fixes, 3D is much more usable now.
