I am doing a glowing border around my cards (in UI image) via shader weaver with the remap tool (to have it animate around the card) and UV mapping for the effect (like you did in the sword tutorial).
Now the performance is fine on mobile - except when I am showing the card in full screen. Then size of the cards is around 700x1100 pixels large - the border of this shader material is behind the card (so I have to make it even bigger e.g. 800x1200) - in order to see the glow behind it going over the cards border. Thats when I see the performance degrades a lot. And I guess that is due to the fact that I am rendering this large picture - with the whole center of the picture being transparent.
But since I would only the to animate the border around (the area from the remap) - I wonder if there would be a better way to do it - so that it gets more performant. Maybe somehow tell the shader that he only processes the remapped border instead and ignoring the center of the full rect - but I have no clue about shaders myself - or do you have any ideas?
I tried to use smalles remap size 256x256 but it didn't help...
Thanks a lot,
