How to set billboard transformBehavior for particleEmitter?

netunlimited opened this issue · comments

I have a particleEmitter that emits Quad particles with a PNG texture.
It uses a Sphere as a SpawnVolume.

When I walk around the particleEmitter the particles at some point are not visible, depending on the perspective. I'd like the particles to always face the user (== the camera). I've tried setting the Node.TransformBehavior.BILLBOARD on the emitter's Node but it has no effect. Any suggestions?

That is strange, particles themselves should always be billboarded to the user. Could the above behavior that you are seeing be due to culling (when you walk "behind" a particle?)
