Question

Unable to Save Substance Painter Project. Says Generating thumbnails forever

I am unable to save my Substance Painter project. It says "[Project management] Save failed - this is unusual, check previous messages for more information"

 

I cant save over the file and I cant save as another file. It runs the message "generating thumbnail(s)" constantly. 

 

Previous message is "[Resources List Model] Icons memory budget set to 100MB."

I have set the local cache budget to 5000 mb so that should not be the problem. I can't find any settings for the Icons memory budget. Is there a way to change the Icons memory budget, and would that help me to be able to save my project file?

    I started having same issue after update, it's so annoying, my thuiumbails are not loading anymore and cash generation doesn't allow saving.

     

    Why Adobe does this to us, why.

    I'm so frustrated , lost work and time...

    Hi @M38908470il0x,

     

    Could you share your log (help > export log…) after the problem occurred?

     

    Let me know.

    Have you found a solution for this issue? It's become a major problem for me. I regularly lose work and additionally thumbnails won't load.

    Hi @___Narv___, Hello @Sean27755537zd26,

     

    Sorry for the late answer.

     

    I don't think the Icons memory budget is linked to the issue. Would you mind sharing your log (help > export log…), so I may take a deeper look?

     

    Keep me updated.

    Sure thing and thanks for looking into it- here is the log. I exported this log after 3+ minutes of generating thumbnail being frozen and the project saving being frozen.

    To clarify, when I say the issues are related, the thumbnail generation freezing prevents the saving process from completing- Because I have a big asset library this will always happen to me eventually, because the project has been open for long enough to fill up the icon memory budget I suppose? I have also raised the budget and tried every other fix for the thumbnail freezing issue I could find- that doesnt bother me so much because I can restart, but it preventing saving has been a huge issue.

     

    Thanks!
