Please, how do I remove the pink "clouds" from particle effects such as fire and smoke?

Hello ,

Thank you for posting in the community and it seems you are referencing the visual helper for the smoke particle. This is visible when selecting the element or if you have the Visual helpers on. You can toggle it on or off by pressing the [ G ] key.

Or in the Preferences > Appearance > Visual helpers have the check box unchecked.

Hope this helps.

Kind regards,

Vincent B.
