Thanks for the bug reports Funk. A few of these are due to a change in the Modo901 API related to how file paths are constructed which the plugin did not compensate for.
BUG: If you have "preview mode" enabled, pressing "kernel > reset settings to default" resets it to OFF
Yes, "Preview Mode" is a Kernel setting - so gets saved to the default. The other option is it could be a Preference setting - but I think having it saved with the Kernel is a better option, since it is then saved with the LXO. Not sure there is any value in adding the "preview mode" checkbox to the Kernel settings - since it's already a button on the toolbar.
BUG: The new "Polygon displacement" toggle is not reset when pressing "reset settings to default"
Fixed in the next release.
BUG: Kernel "Save settings as defaults" no longer works
Fixed in the next release.
BUG: Kernel "Reset settings as defaults" is resetting your render passes options
Fixed in the next release.
FR: Please add a "Reset/SAVE settings as defaults" commands to the Render Passes settings
The render passes are saved on the Modo render item - so their defaults should be saved/loaded via the Kernel settings. Splitting these out into a separate save XML file causes issues when the Kernel "package" is created when Modo first starts - because the defaults for the Kernel are coming from 2 sources rather than one. With enough time this could be handled - but it would be an overly large time investment for a marginal gain IMO.
FR: Please add a "Reset settings as defaults" command to the Environment settings
Done in the next release.
FR/BUG: 801 and 901 "save settings as default" are stored in the same place. Please separate them
The default files should be fine servicing both Modo801 and 901 with the above bugs fixed.
The 801 setup window has a "lock" button which prevents material changes from affecting the render. This is missing in 901
Fixed in the next release.
Thanks
Paul
