i got a problem.
on my other acc i got flame.
i have also a flame particle texture.
so the problem is that i deactivated the flame particle texture but particule on my flame stays.
the same is with texture trails...
what should i do?

Go to your own folder, it's located at Toribash> custom> Look for ToryDude. After that, delete the image flame.tga. That should work. For the trails delete the trail images.

ok another question.
ehy does the flame some times is like squeres nor circles?

Depends, did you upload that ''circle'' with a transparant background but didn't save it as a .png? .Png supports transparant bg's so it won't appear as a square.
