Video of few levels from low budged FPS I was working in 2007-2011. Aside doing those maps ( which with the LD we had about a 6 weeks for everything))) I was responsible for lighting for couple other levels we had made by other artist and made a material we used for all environment assets.
At some point we had no FX nor animation support so I had to make fireboom on the oilrig just with the geo. Plus this was an older UE3 build so we had no access to vertex animation and tonemapping ((
I cut it of the old reel so it is a bit choppy and low quality.
