Aura 2 strictly requires full support of the following elements to work :
▶ RenderTextures (3D as well)
▶ Texture2DArrays
▶ ComputeShaders
Please verify that the support of these elements is not limited especially on lower platforms.

Aura 1 and Aura 2 are not compatible with each others.
Please delete all references to Aura 1 before importing Aura 2 in your project.

Aura 2 does not support SRPs, LWRP, URP or HDRP.

Aura 2 was developed and tested on Windows and DirectX11.
Other platforms and Consoles are on their way but are currently not guaranteed.
However, experienced users have reported Aura 2 successfully working on Vulkan, Linux and MacOs + Metal. No support can currently be provided for those platforms.
