I’m currently trying to reproduce the purple elemental ball that can be see in this artstation post.
But I have some trouble seeing how I can achieve this texture moving from the outside to the center of the sphere
Did anyone have somes clues or ressources about that kind of shadder effect ?
Are you certain it’s a sphere? It’s an easy effect to reproduce with a flat surface, and I think it would hold up equally well as long as it’s facing the camera
Actually I don’t really know, but you’re probably right.
Actualy i’m searching for any way to reproduce this effect.
Did you have an idea of how this effect was made ?
I was thinking about using a circle and making the texture scrolling from outside of the ring to his center, but i’m not sure how to make my texture scroll
Use a Polar Coordinates transform on your texture coordinates before you add the panner.
Thank you for the help, I will take a look at this 
You can also create a custom mesh. Like shown by Shannon here:
