Im certain this was reported years ago but im not sure its ever been dealt with.
When opening a CXR with CIE, The lightmix settings, whilst displayed in the UI correctly, arent displayed on the image correctly.
i.e. if the environment is disabled in the saved cxr, when opened it will display as disabled in the lighmix tab, but will display as enabled in the image.
The solution is to toggle any of the lightmix checkboxes and itll display correctly.
However a problem arises when you go to use the command line CIE to export layers to files. Theres no opportunity to toggle the lightmix settings so everything gets saved out with all of the lightmix layers enabled and at 1.0.
Not a huge problem but it would be good to see it fixed in a later version. Im sure the number of people using command line CIE is minimal.
