I have a question for animation graphics. I bought commercial color matcap overlays for 3d designs and renders.

I suspect that the author created the matcap overlays using Ai generators but I am not sure because the online store nowhere writes how the matcap overlays were created etc.

If I use these matcap overlays in my projects for animation graphics is there any risk?

Should the agencies be interested in how I created the animation graphics?
