Panning UVs Problem

10 years ago • updated by 10 years ago • 5

When i pan the UVs with a Panner Node, or manually by adding time to U or V(or both), it distorts the texture if the panning speed is getting higher(does not have to be that high to occur), the higher the speed the worse the distortion... What could be the cause of this? Is there a way around it? Is it a bug?

Looks like precision issues, I'll look into it in a bit!

i think it draws the same pixel for every pixel that gets panned within a frame, therefor it gets worse when the pan speed is bigger. the image above also indicates that, as it looks like rows are taken and copied over in the panning direction...

Does it still happen if you restart Unity?

And how does your node tree look?

had problems to get to the issue again as i had it before, its still there but on the recreated shader i have to use higher panning speed to get it to look as worse as before. Maybe restarting unity helped but i am not sure...

the shader was using wordspace uvs like this one:
