Objects and Flat Images/PNG Sequences always face the user/camera

[ROJ Design]

So I'm trying to recreate smoke in my scene and I'm testing out a sequence of transparent .png files to show the smoke moving. It looks great when face on but as you move around the .png sequence you then see it's a flat plane. The ability to get that plane (or 3D object) to turn and face you at all times would then fake it to make it look like it's really there from all angles. I'm thinking that it would need to pivot around the y axis only (but an option to choose axis points would be useful). Many thanks!

Hi ROJ Design,

You can easily achieve what you want with Aero's Behavior System.

In Aero's Behavior Graph, you can add a Start trigger with an Aim action set as follow.

You can enable the Bilboard only action if you want to restrict the rotation to the Y axis only, or leave it disabled for a free-form rotation around all 3 axis of the image plane.

Perfect! Thanks so much for your help. Shame on me for not knowing it was there. Doh!
