3D models Made for RF-X. A Radio Control Flight Simulator for the PC. I had modeled over 100 RC scale aircraft and helis products from the RC industry while working at Bourke Ent. LLC.. Models ranging from 14k to 65k polygons all with 2048k maps. PBR textures were all processed with Substance Painter . Models were imported in the Unigine engine, where final materials were adjusted.
