After a long time, an update with some fixes. Info: https://ephere.com/plugins/autodesk/max/lucid/ Changelog: Fixed: Crashes when Lucid modifier state from Fluid to Cloth Fixed: Lucid Attachment crashes max when set to use Time Range with a start time above frame zero Fixed: Lucid toolbar is not added to all workspaces in 3dsmax 2018 and above Fixed: Lucid Toolbar buttons wont work on Max 2018 It still needs CUDA or DX11 so no way for me to simulate with it. Which is why you get a glass-fill before it has taken place. Of interest (it might have been there on the previous version(s) but I never paid attention to it): On the small image, I circled an option. It refers to 'hair'. There is code in the plugin for it but no interface calls for it. Easy to add but I suppose there is a reason for them missing. Maybe it's still under test. Anyway, something to look forward to.
