This is my discord, if you want we can try making something together: swetroniusz#3020
I'm working on my entry using my own 3D engine. It doesn't have flashy features like raytracing/global illumination and I won't be able to do super complex stuff in 2 weeks but it should be fine if it's simple. PBR, physics using PhysX and basic 3D audio works though.
Your models are looking sick, with some work on my side I should be able to render this.
