Opacity On effects

Opacity parameter on every effect would be nice, or 'wet/dry'.
Find myself creating lots of extra blend/mix modules to get the right look sometimes.

Ok, thanks. That's probably doable for most of the effects modules.

This is reasonably simple for ISF (and likewise GLSL shaders) but tedious to go through all files, and for the built-in effects these will get overwritten on any new, update or re-install, and of course many built-in effects are not ISF.
Add a float parameter (e.g. 'dry') then add this line to the end of the main:
Code: Select all
// wet is the output rgba of the effect
gl_FragColor = mix(IMG_NORM_PIXEL(inputImage,uv,1.0),wet, dry);
+1 if automatically applied to all FX and bypassed when the effect is completely dry.
I've done this with a few modules but make sure to default the parameter value to fully wet - to not change your existing comps.
This brings me to a related consideration: when live, I often want to add nodes into the mix which, for many effects, is abrupt and jarring. I will often add an unconnected node, configure it to leave the output unaffected, then connect it (cut then paste insert on a noodle). It takes time to do this and it would be good to have and option to insert nodes completely dry in certain situations.
