When opening previously saved (with RPRv1.6 and lower) files that have Use Clamp set to Clamp Irradiance = 1.0 the new RPR 1.7 plug in re-sets this value to 10.0 causing an increased number of "fireflies" in the scene.

When opening old files where this value was already set the new version should respect this.

If the new default is now 10.0 on new files that is fine.

Once re-saved in RPR 1.7 with a new setting subsequent re-laods do respect the newly saved setting if you change it from 10.0 to something else.

So we moved around the setting a bit (unavoidable unfortunately).  So this setting and a few others might need to be reset.  Either way like you said it should be a set once then you're good to go, and only an issue with old files.  Sorry!  I'll add a note in the release notes.

Actually I just fixed this, not sure why the default was changed.  Next build will have it reverted
