This is my 3rd attempt to get this crash through QA, now posting in the forum, which hopefully boosts its chance to get reproduced this time. Creating a Texture3D asset causes the editor to crash. Please see the attached video, which shows that this works in 2019.3, but causes a crash in 2020.1. Reproduce Create new "3D" Project or open attached project Install "Texture3D Atlas Import Pipeline" package from git https://github.com/pschraut/UnityTexture3DAtlasImportPipeline In Project window right-click and choose "Create > Texture3D Atlas" Press Return to confirm the asset name Actual Unity editor crashes. Expected No crash. This used to work in Unity 2019.3.
