Newest Blender on Raspberry Pi seems to be 2.7, which works surprisingly smoothly under a 64-bit OS. RPi4 has 96 Gflops of CPU FPU power, making it a reasonable option for 3D-rendering for kids.

I hope there are chances to get 2.9 to run on Raspberry Pi, especially once RPi Vulkan support matures.

How's Blender Vulkan rendering path doing? Is is possible to use it instead of OpenGL one day?
