For some reason I can’t submit a bug for preview versions, but it’s pretty simple:
RenderTarget crash with “Auto Generate Mips” in DirectX 12:
- Start a new project (i used first person blueprint)
- Once open, in Project Settings->Platform->Windows, switch the default RHI to DirectX 12. Restart the editor.
- Create a new RenderTarget, open the asset and check “Auto Generate Mips”. This crashes the editor. If you repeat the steps with DirectX 11 as the RHI it will not crash.
