Hey Adrien! I followed your recommendation about setting PCG components to 'Load as Preview' editing mode, and it solved our source control issues. However, I'm running into a problem when iterating on graph parameters via PIE. Since the components are in Preview mode, PIE loads the previously serialized ISMs (generated by the build machine) rather than reflecting my current parameter changes. Triggering a rebuild through the build machine would reintroduce the source control conflicts we were trying to avoid, and it's also time-consuming. Is there a more elegant way to see up-to-date PCG results in PIE while keeping components in Load as Preview mode?

Hi! I'll have to check when I'm back from GDC. I think we already spotted that and I need to verify if we managed to make preview changes transfer to PIE

Curious about this topic as well. It's a shame your talk is behind the GDC Vault paywall. Is the slides or a summary available somewhere?
