A demo plugin for Adobe Lightroom to demo a bug in the LRC 9.3 update SDK release, to assist the Adobe team.

Adobe Lightroom 9.3 SDK error Demo Plugin

This is a demo plugin designed to help the Adobe team identify an issue in the LRC 9.3 release

An issue was identified and originally documented on the Adobe Community Forum, and then a bug-report was raised on the Adobe Forum

A rep from Adobe reached out asking if I could help them by providing a sample plugin that demostrates the issue. This is the sample.

Steps to reproduce

1. Install the plugin from the preseterror.lrdevplugin folder in this repo.
2. Select an image, and apply some local brush adjustments to the image.
3. Trigger this plugin by selecting File > Plug-in Extras > Preset Error Demo > Apply Setting.

In LRC 9.3, you'll notice that the generated plugin preset of increasing the exposure is applied, but also the Local adjustment added to the image is removed. All other modified settings remain unaffected as expected.

This behaviour is the same for all "Corrections" (Local Adjustment Brushes, Radial and Graduated Filters) applied on an image.

Here's a video showing the above:

Hope this helps.
