I deactivated my FPT. I deleted my flame.tga in my folder.

My flames turned into a black square flames.
How to change it back to the flame's original form?

The Tori folder in the custom folder is basically the base of what all tori's will look like. The square usually means that the flame.tga in the tori folder is missing.
You can try to reupload your flame particle texture, or /dl yourself if you already have one.

I deleting the flame.tga from there, too, so yeah...

So what should I do to have my flame particle come back to it's original then? Not the FPT one or even the Big Square one.

Instead of only deleting the flame.tga, just delete your entire custom folder and /dl yourself again.

Already did like 3 times. It's just the same.

You can get the original particle texture image if you /dl uke

Copy the image to tori's folder (i advise keeping it in uke's folder too)

Thanks!
