Hi !

I got a question about the "Set Matte" effects

I want to use it on a ".png" files, to make appear a YT Logo on my animation, but it don't works while it does on a text, so IDK what to do. Anyone got an idea please?

Thanks 🙂

Set mat needs to be pointed to a file that has an alpha channel or high contrast (black and white) values to create transparency. We need you to drag a screenshot into the reply field on the forum that shows the modified properties of your problem layers to figure out where you are going wrong.

Well, I want to use the "Set Matte" on this logo, the Matte is linked to my "YT_Logo"

 

and I don't have any modifications (excepted the position of the Matte)

I hope that I give you all the informations you need !
