Being unique on platforms like Twitch is very hard nowadays.
A lot has already been done, created and performed.
One thing what I noticed is that every streamer has flat 2D graphics.
With my 3D skillset I had to create something cool.
That's why I completely created my own real life bed and streamroom in Blender and use it as offline screen & intro for my streams.
