Making a world model using a Doom sprite as reference, and then making a crappy view model from it. I recorded this for future reference in case I forget some part of the process, the videos may be useful to someone out there. First video is making a world model from zero to in game, second is using it to make a simple animated view model, the end result sucks but it shows how it's done. Blender addon that displays key presses doesn't show some presses sometimes, mainly axis buttons when scaling/rotating. I skipped a couple small steps like running the texture through a padding plugin in Gimp, aligning UVs to pixel centers, and small last minute texture cleanups. When there's an important setting I waggle the mouse next to it for a bit.
For some reason embedding doesn't work, first video: Youtube.com
second:
