The only crashes I seem to be having with PGI is when trying to re-work an old scene (which is probably already a mess due to my learning curve), and then swapping an old MATTE node with the new Disney appears to fix it.
Otherwise it feels like working with an ant on speed!

Sounds weird, can you post the scene (possibly simplified while still reproducing the crash)?

I think I've already updated those scenes, but I'll look through the archives and try and find one that is still faulty.

@Dade
is there some rules to follow to have the best results fomr the PGI?
For example I'm doing
some tests trying to understand how to reduce/remove noise from that part of the scene.
A mirror material should still has the "use photon GI2 option enabled?
Is a particles sytem used for carpet something like to exclude from the PGI?

PGI cache is never enabled on specular materials (mirror and glass) so it doesn't matter (probably BlendLuxCore should no show the flag at all for specular materials or show a explanation label).

Only if you need to save memory otherwise you can just use the default settings.

This is also from an old scene (December 2018)and is creating a different error than the one mentioned earlier ‘Matte to Disney shader fix’. I hope it’s of some help. (Scene link and message attached)
I would have created a new post for this in User Support but I can't see the option for that any more?

Thank you
Are you using a persistent cache file written with another version ? It looks like you are reading some kind of binary LuxCore file saved with a different version, or mixing different types of LuxCore binary files

Yes, I think by the way in which I've been re-working old scenes, that is probably what I've inadvertently been doing.
Thank you

I've deleted the old Untitled.PGI file and also tried switching OFF PGI but am now getting a new message with the same scene (attached)
Thanks

Can you post the console output? It should contain some traceback about the error.
