I recently had a job interview with Payload Studios and was given an art test which I had to create a 'block' for their game, Terratech. The brief was to create an asset in the style of their game that was 300-1500 triangles and had albedo, metallic and smoothness maps at 512x512. I also had to provide rough sketches of my concept ideas and import the assets into Unity.
I ended up creating two weapon assets because I couldn't decide which one I liked more. I wanted to fill a gap they were missing without going too out of the box. I came up with a 360 Shooter and a Plasma Gun. The Plasma gun is 615 triangles, the Shooter is 630. I used Maya, Photoshop and Substance Designer to create these assets. I loved it! Making something keeping in mind an existing style and game was a really fun new challenge.
