For this first terminal, I created a collection of kitbashable electronics, which culminated in a pretty retro-futuristic cyberpunk device. I scribbled out the initial terminal idea in Photoshop, and then modeled and rendered the result in Cinema 4D/Octane, with post-production in After Effects.
I modeled this next terminal entirely in Blender, and then brought it into Substance Painter for materials and texturing, then back to Blender for the final render.
These are some of the components I modeled out for my retro terminal kitbashing.
