I am creating photorealistic spacecraft animations and I would like to add reaction control system (RCS) thruster effects (see the linked video for a real world example). As I've never worked with Blender particle effects, ideally there might be a 3rd-party product or tutorial to get me started. Any suggestions? Thanks. Blender 3.10, Windows 11

You could fake it with a material on a cylinder: You need to mix an Emission with a Transparent node with a Noise Texture as factor, then mix with a Transparent with a Layer Weight as factor (to create a gradient on the width), then mix with a Transparent with a Separate XYZ as factor (to create a gradient on the length):

    $\begingroup$ Actually I plan to build a reactor but I'm afraid it will take several days (plus Elon doesn't want to help me) $\endgroup$

  • $\begingroup$ Yes, I told him to hire you, I told him "Hey El', do you know this guy, Chris? This guy is really talented in Geometry Nodes, you should hire him", he told me "yes but I heard he was a bit lazy", I tried to convince him that you were not, glad he hired you after all $\endgroup$

  • $\begingroup$ Yes, I know. Laziness is my second name. So I have to say „thank you moonboots, that you made me work for El, who made me a multibillionaire…thank you! $\endgroup$
