This is a still from a studio competition we did at work. This is from the final compositing stage. We were supplied with the camera matched live action footage and the 3ds max Apache model. There were 3 stages, animatic, lighting and compositing. Rendered with Vray. Did sky replacement in 3ds max, heat haze, muzzle flash, added a few live action vfx and color grading in AE. The clip is on my website.
