hello jmonkey community,
I’ve a problem with the particle meshes.
I want to create an engine (for a spaceship), but I still get problems with the flame.
The engine isn’t showing particles on the x-z layers/axial.
As an example I edited the third-person-example (ParticleOnNodeTest.java)
Screenshots:
Can you tell me how to write it to show the whole flame on any axial?
ParticleOnNodeTest.java
