I know I will never be a great writer, so instead of doing tutorials, I have decided to release some of the personal project I’ve worked on. The result is a 300MB folder of 22 project, including a lot of the things on my portfolio and demoreel.
When I was learning Blender, I start a lot of personal mini-project that I never really finished, so instead of having them just sitting on my harddrive, perhaps others can find them useful in some way. The pack contains animations, stills and a realtime game project.
