I wrote about this at Daz forum, but no one could help me and the support ticket is taking time too, so I'm giving it a shot here. When I select the Node Weight Brush Tool to paint some weights on a figure, I can't see the normal red-to-blue gradient. instead, whatever weights are bone has is displayed in all red. It doesn't matter whether I'm working with my custom figures or the default ones like Genesis 8, 3 etc. I tried several tutorials to see if I was doing something wrong, even tried reinstalling software, but nothing changed. Has this happened to anyone? Any idea how to fix it?

The issue is solved! I'm leaving this here in case someone else wondered too. Uninstalling the software and all the content, cleaning registries manually as well as running ccleaner and updating Daz studio did the trick.
