I'm working on my thesis on Generating Starfields in 3D and have run into a bit of a problem.
Following suggestions by Tolerate and Mr. McKinley, I've created a Starfield using particles. Specifically, this is done by placing an Omni emitter at the origin, setting speed to 0, minimum distance to 600, maximum distance to 900, and then letting the emitter fire away until I have the desired density of stars.
From there, I wanted to add some variation to my stars. Not being too confident with per-particle attributes, I figured the easiest way would be to create a couple more emitters with similar settings and have these emitters fire different particles.
My current set up has three Omni emitters all at the origin:
one for bright yellow stars
one for medium bluish stars
and one for dimmer greyish stars.
Ideally, this would randomly fill the sky with random placements of these three types of particles.
The problem is, all three of my Omni emitters appear to be firing at the exact same locations in space! When all three emitters create a particle at the same spot, the large yellow ones are always seen (being the largest) and the blue and dim ones are unable to be seen, always encapsulated/blocked by the yellow ones.
To prove that this is the case, I put the three different particle types in three layers. If you view them independently, you can see that particles from all three emitters are being placed in the same locations.
How can I fix this?
I tried rotating the emitters, but this made no change.
Also, if MTMcKinley, Tolerate, Oculus, or NitroLiq happen to view this post - I'd love to give you guys credit once my thesis is complete. If you're willing to give me a little personal information and would like the credit you most definitely deserve, send me a message here or an email to email@example.com
. Your full name, and then the company and/or college you most strongly affiliate with would be great.
Thanks in advance,
