NOW SOLVED... see below
Well thanks to KISTech I've solved my transparency issue, now I have another question:
Is it possible to have particles with no gravity?
I've been playing with the Particles sample app and changing the line:
Quote: "dbSetParticleGravity ( ParticleNumber, 2 );"
To different values but they all either move upwards or downwards.
I've also tried without setting the gravity, but the default without using that command is 5 (so particles fall downwards after they have been emitted).
What i'm looking for is particles that shoot out of the back of the object/position but don't move upwards/downwards after, so just a smooth trail of particles are left behind.
Is this possible with the internal DB particle system? Or would you advise writing my own using e.g. dbMakeObjectSphere and using transparency/ghosting effects etc.
Thanks for any help!
EDIT: Actually, I've solved this now by using the dbSetParticleLife function, here's a pic:
I can upload the full source to the modified Particles sample if someone wants it.
