Description of the bug

Using "Layer range selector" (Synchronize checked)
Changing the exposure time of a layer results in the starting height of the plate to be several mm above the FEP.

I also tried just editing the lift height without exposure changes and the result is the same.

How to reproduce

Change a layer parameter with the layer range selector on the Mega 8K S - either lift height or exposure time.

The goo format is showing problems when changing parameters per layer, if perlayersettings flag is activated it causes problems.

Thanks, appreciate the reply and your amazing work on this - to clarify this is a .prz file but I'm assuming it applies as well.

Is there any way to keep the lift height the same across all base & transition layers (instead of just base layers) without activating the perlayersettings flag?

Otherwise in the very first transition layer, the lift height switches to "normal" but the exposure time is still very long - which is often not enough. Otherwise I have to compensate with high "normal" lift height for the entire print.

prz is goo format.

Is there any way to keep the lift height the same across all base & transition layers (instead of just base layers) without activating the perlayersettings flag?

No, any different setting will trigger the flag, and flag off mean layer settings are not respected.
Only UVtools uses this flag in format, no other tool or slicer use it, so is not well supported, buggy and a no-feature
