I'm trying to create a Material Blend between two material instances like in the tutorial video, but I always get a crash.
I want to point out that this doesn't happen on all materials, but on some I get a crash 100% of the time,
For example the one which gives me always crash is trying to create a Material Blend between these Megascan assets: 04_Bright_Desert_Sand_2x2_M_sjzkfega_2K_inst from the Bright Desert Sand material and the 04_California_Coastal_Rock_skhxk material instance.
The log gives this error
Assertion failed: [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 570] Attempted to create a package with name containing double slashes. PackageName: /Game//Master_Materials/SurfaceBlend_MasterMaterial
Not sure why it's trying to create a package with double slashes, and to be sure I've checked the master material and all the textures referenced and none uses irregular symbols.
I'm on UE 4.22.3
