I have written a graphical engine that works both on desktop and mobile. And with this I've written a MMO game.
The problem is, certain graphic effects are glitched on mobile, mainly those that use texture matrix multiplications.
Here's a video of the game:
Check out the video at 0:15, the snow effect is done with a tiled texture that is moved around with texture matrix translation. In Windows it displays correctly, but in mobile (as in the video), it seems that the texture is clamped.
What could cause this?
