It seems like VrayBlend materials are crashing the Engine when importing them with Datasmith.
This is a regression from 4.24.3 (CL-11590370) where the file imported successfully.
This was reported and tested in 4.25.1 (CL-13594126) and reproduced in Main 4.26 (CL-13653677)
Results: The Editor crashes during or after import
Expected: The file is imported successfully
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-94430 in the post.
