I have set up a TS1 preset after the Greg Rostami technique, which uses Topaz Impression and Topaz AI ReMix. When I change the opacity slider in AIR using the TS1 preset - it changes back to it original setting.
The TS2 version on the other hand - I take the AIR opacity to 0 and back to 100% - and a completely different (and much darker) result!
I suspect we might have to accept that TS2 presets will behave somewhat differently to those brought over and made in TS1?!
Here is a video of the difficulty - you can skip to about 1m30s before the TS1 opacity change may be seen. At 3m20s the much different result in TS2 “of the same opacity change” in AI ReMix may be seen. The video quality is much better when watched at YouTube itself.
