Particle system only rendering on one side

Hello

I am using a particle system that I have found on the marketplace, which creates some smoke floating upwards.

The effect only seems to render in the level when looking at it from on side. But if looking at it from the opposite direction then nothing. Rotating it or scaling it doesn’t seem to change that it only shows from one side.

Any ideas?

there are a couple possible reasons. first see if there is a lock axis module. what that does is force the particle to face a specific direction or rotate around a specific axis.
Then you could also check the required module there is a drop down list of options for screen alignment.

@IndieGameCove’s comment is probably right on why you are getting this behaviour. Particles usually face the camera at all times, like billboards, if any axis is locked you will get a rotating billboard.

Another thing you could try is to check if the materials used by the particle system are double-sided or not. There is a checkbox you can tick in the material editor. If you can see the particles after ticking this box it will be because the particles billboards are rotating and not facing the camera at all times.

Yes, making the material double sided, along with ticking the option Orient ZAxis toward camera seems to have resolved the issue!

Please note that the double-sided material was for testing only. Since you locked the orientation to the Z-Axis you should disable the double-sided rendering since this can be expensive depending on the number of particles you have.
