So that's the problem in a nutshell. I have a three different particle simulations going in a composite shot. Nothing too particularly intense in the layers. Not much else going on. A 3D model of an X-wing with a particle sim for the exhaust.
In any case, it kept crashing with a GPU warning so I decided to upgrade my 750ti to a 1060. I am still having crashing issues (though the GPU warning went away) and the most recent crash has made two of my particle sims just not show up anymore. The layers are still there as are my settings for the particles themselves but the actual particles and their respective emitters just aren't appearing in my composite shot. The X-wing is still there but not the exhaust.
My CPU is an i5 and I have 16GB of RAM.
Thanks for any thoughts on this,
Addendum: Turning on 'preview' causes some very rudimentary particles to appear though nothing close to what I had prior to the crash.
