Hey,  I have a probleme with the color gradient withe the model "huge image transposition".

I would like to do exactly like the model Image to Black but color gradient the trensposition of effect desepear whene I save the modifications. 

And even whene I change nothing in the original picture, just the fac I save whene I open the parameter box. Delet the degraded.

I show you in attachmen, 

My goal is to do a smart degraded picture -> black not a brutal image to black. 

Thank you for the help, 

Adrien
