I am moving from Lightroom 5 to the new version. I bought Lightroom/Photoshop through the Creative Cloud option. I frequently accessed Topaz Labs products through Lightroom 5 but I cannot figure out how to do this in the new version. No edit in options and "preferrences" is very limited.... I must be missing something???
If you are using Lightroom Cloud (version 3.4), the application does not have the option to install plug-ins hence you can not use the Edit-in option to take the images to plug-ins like Topaz. For such workflows, you can use Lightroom Classic which is the successor to Lightroom 5.
If you have purchased the Photography plan (Photoshop & Lightroom), you should be able to install Lightroom Classic through the Creative Cloud desktop app. For the feature to install plug-ins to Lightroom cloud, you can submit a feature request here: https://feedback.photoshop.com/
