Xparticles not rendering the amount of particles in the IPR

[cassidydodge2]

Hi there,

I have a pretty simple XP setup with one emitter and a spawn modifier with a corresponding emitter. The particle movement is controlled by a Flowfield. The IPR seems to render everything fine but an actual picture view render is missing the majority of the particles from the spawn (but not all). Once cached with the XPcache object, I get the same result as in the picture viewer render. I'm guessing this is more of an XP issue? But thought I'd see if anyone here could help shed some light on this for me.

Thanks

Here's a screengrab of a render versus what I see in the IPR:

It's strange... Feels like the render is behind in terms of particle generation and/or speed?

The fact, that caching the simulation has the same result as in the PV originally, might indicate that it's a problem(?) in X-Particles itself. You can also check the result of other renderers (like the builtin Standard or Physical) to be sure.

The IPR displays what's in the active scene, what you can see in the viewport basically. While rendering to the Picture Viewer operates on a cooked render scene. Ideally they should match, or the active (IPR) scene should have lower level of details.
