Unreal Engine Issues

UE-94430

Unreal Editor crash on Datasmith import with VrayBlend Materials

Unreal Editor crash on Datasmith import with VrayBlend Materials

Description

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)

Steps to Reproduce
  1. Download and extract the attached files
  2. Open the UE4 Editor and create a Blank Datasmith enabled project
  3. Import the udatasmith file

Results: The Editor crashes during or after import

Expected: The file is imported successfully
