Ive just completely re-installed Xsyon because of crashes to desktop
(the crashes to desktop is cured so far)

But i have new bug in a brand new install

I cant see the flames of any fire.

I see its light, I can cook on it, but the fire has no flames animation.

Other people can look at the same fire and its fine on their screen.

Ive heard that a file needs to be renamed but ive no idea which file

Ive looked in the Scripts folder and theres lots of files with the ext .fx or .fxc
but there is one file with the exstention .effect

the file is fx_001.effect

Is the file i need to rename ?

thank you
