Comparing how blendmode are working in software such as Photoshop, Gimp, Blender, Davinci etc… and also in vvvv Beta, there are some bugs and behavior issues in the Gamma textureFX :
First the fader has to be set to 0.5 instead of 1.0.
Now I haven’t tested all of them but here are a few examples with the middle being from GIMP :
Multiply (the alpha shouldn’t multiply)
It’s cool that stride comes with more of them but for sure the Normal blend mode and its behavior is missing and other “standard” one have problems.
