Does anybody know how I might change the size of the flame produced by a fire particle emitter? There are no size parameters in the modify panel for the fire that came with the iclone 7 that I bought, or in either of the two other fire particle emitters I've bought from the marketplace either. I thought I might reduce the size by attaching it to an object, then scaling that down, but that didn't work. As it stands, I may have to draw onto individual frames after I render to achieve the effects I seek, but that would be tedious in the extreme.  Any help with this would be greatly appreciated.

Is the fire particle a legacy or a popcornfx particle? (It should say so in the content manager snapshot) if it is legacy go to the modify tab and you will find a section named particle key there you must adjust the size in pixels for each of the four keys represented by a triangle. If it is a popcornfx particle and you don't see a popcornfx tab you need the popcornfx plug in in order to edit its parameters

If it's Legacy , you have 4 keys when you can choose the size.

If it is popcornfx Library 40 particle there is a Global scale .



If it is Popcornfx Super Tools Texture emitter you have "Global scale" and a  size feature in the "lifetime" Panel

For some reason, no matter how much I scale down the legacy flame (even to zero.) it didn't shrink one bit. Maybe that was
because I'd already attached it to something. But following your suggestions, I shrank down the popcorn fx flame to just the
dimensions I needed.
Thank you!
