I dont believe that I am the only one who has this issue.
I have tried different PCs and different projects and I have the same result - crashes.
I cant work

Hi @Ingolmil . 0
Are you using 4.26.2 Engine with Substance Plugin 4.26.0.21?
Are you using a Substance material from Substance Source, if yes which Substance?
Are there other other Substance materials which also cause a crash in your project?
Can you give us your system configuration; CPU Cores, RAM, GUP?
Thx,

Yes

I have a problem with any substance material. From Substance Source and any sbsar file from other sources.
The crash occurs when im clicking on the viewport after modifying the substance graph instance.

Can you give us your system configuration; CPU Cores, RAM, GUP?

Hello Ingolmil . 0

I was able to reproduce the crash and wrote a JIRA ticket for it.
Sorry about the inconvenience. I will update you when I get a feedback from our development team regarding this ticket.

Thx,

Wanted to chime in to say that I'm also hard blocked on importing any substance files into a 4.26.2 project now due to this crash.

The substances I'm trying to import are from this pack: https://www.artstation.com/marketplace/p/7eO0y/tiles-materials-vol-1

I am on a custom build of the engine but we are using the stock Substance plugins from the marketplace. Current Substance plugin version is 4.26.0.21.

They worked in an earlier minor engine version so I believe it must have been an issue introduced at some point recently.

I am on a Ryzen Threadripper 1920X, GTX 970, 32 GB of RAM

Can provide more info if necessary, please reach out. Thanks!
