Any render of any project leads to that : ...

Hi there,

Deeply involved in a project where I key with Primatte in Fusion 8 Studio, I realize that whatever I render is messy (see attachment)... It comes at a certain time of rendering.
I saw that in a very complex space project months ago and thought I may have to tweak a specific node, but actually it happens on everything I render, even a simple 3 nodes green key , and it's not only what's showed in the GUI (what I prayed for), but also in the rendered file... I'm desperate at this point...

Whatever I choose (CPU, GPU 1 or 2) in the preferences, same render...
I'm on a legacy MacPro, 8core, gtx 680 + gtx 980 ti

Ideas ?

That's watermarking.

Huh ?
First, thx for your reply, but I still don't understand.
How can watermarking have anything to do with 1/ Fusion Studio and 2/ this specific project involving 3 nodes including a Primatte Keyer one ?
Isn't watermarking made to act as a limitation of a free version or something like that ? Does Primatte Keyer need a serial number ?

Ok, fixed, shame on us (don't ever mix studio and not studio interact in the same app folder)
Sorry for the inconvenience
