Hi again,
because I want to use FF in PhotoImpact as a plugin for choosen parts of the picture I tried the following (needs a lot of ram, I am afraid...??? - and works precise only using FF-textures without transparent parts, I think for the moment...):
1. I First make my mask, object or so in PhI... - because it is not shown as mask in the next step I recolore it in a special colour before calling DeepPaint if I dont use a transparent FF-filter)
2. I call as plugin/effect in PhI the before installed plugin/program "DeepPaint" (2D-version is free now in the web - I found it "googeling" for free graphic-soft...) - a great program !!! - as "standalone" and as plugin... - and it itself uses FilterForge as plugin...
3. In DeepPaint I make a (rough) mask over the region my PhI-mask/object is - for transparent FF-filters I must guess - or I have the pre-coloured area... - or I fill the picture... - as I want it...
4. In DeepPaint I call the plugin "FilterForge" - the usual part...
5. Then I transfer back to PhI... - only the object/mask/choosen area will be changed!
My first trys seem to work... - maybe for other programs that don`t want to use FilterForge it works, too... - I will try in the next days...

PS:
If You don't need it in PhI:
only "DeepPaint" is worth a try !!!
