I had Slicer 4.10.2 version on my PC. After a while, I noticed that for some images the uploading time is too slow, so I installed the latest stable version 4.11.2. In the latest version, I have no problem with the uploading time, but I noticed a difference in how these two versions display the volume in the volume rendering module (screenshot attached, on the left - 4.10.2, on the right - 4.11.2). Slicer 4.10.2 seems to provide more accurate volume rendering (less noise, smoother texture). I noticed that for these two versions, the scalar opacity and scalar color mapping are different for the same image, so the reason seems to be in the fact how the default values are set for the opacity and color.
Could you please tell me why the renderings are different and what I should do to get the same visualization in the latest stable release as in 4.10.2? I know I can adjust the visualization manually, but it would be nice to get a nice visualization like in 4.10.2 without any effort.
Note. This screenshot is only to show the difference - unfortunately, for confidential reasons I cannot post images where this difference is more noticeable.
