Hi,

I'm following the procedural desert PDG tutorial, but i have an issue on the bake PDG feature in UE :

When i press "Bake" in the PDG section, Unreal immediately crashes giving me this error message :

Assertion failed: (Index >= 0) & (Index < ArrayNum) Array index out of bounds: 0 from an array of size 0

I found people with the same issue but nothing to resolve this. Are we doing something wrong? Is it a bug?

I'm working on UE4.26.1 (same issue on 4.26.0) and on the last Houdini and labs tools daily builds i found(18.5.515).


Does somebody know a solution?


Regards,


Romain
