Hi guys,

I just posted a very basic quick-tip/tutorial for rendering X-Paticles within Octane on Vimeo. It just covers the basics but might be helpful if you literally just get started.

@Aoktar: While doing this tutorial I experienced a render bug when using motion blur on particles. Please see minute 19 on video.

Cheers
Dan

Thanks for great video. Watching... Problem can be related with LV buffering on motion blurs. LV is not working as sending a refresh data to renderer. So it's very open to get this kind of glitches on motion blur generation. It's critical that if it's occuring on animation rendering.

Thank you! I've been messing around with the X-Particles demo for a few days and this came at a perfect time.

Hi dbalzer,

nice tutorial, also the ones from tomabobu!
Will go deeper into this the next weeks, so hope we can share some experience here.
To use different geometry than just spheres, we need to use the python script from tomabobu for now, right?

I justed purchased X-particles 3.0 from GSG, they have a NAB discount, ending today. So if anybody is interested and wants to save on this.

H Chris,

Thanks, it would be great to have small group of people sharing X-Particles tips and tricks. I think Toma, who wrote the Python script, would be well up for this as well.

Re your geometry question: You can use whatever geometry you want within X-Particles by using the xpgenerator and drag your desired objects in there. Just turn off particle engine otherwise Octane would additionally create sphere particles as well. The Python script was made to transform particle values into something mograph can read. So apart from different geometry you'd be able to use random color shade etc as well.

I follow your video, but I don't have any display when I have a motion blur rendering. please help me.

Hello, guys
Unfortunately I'm failed to render the X-Particles scene in Octane. Whatever I did — nothing helps. I even cached the animation and tried to assign different materials to the emitter. Here is the screenshot: http://prntscr.com/bcyenh
Octane just doesn't see my particles. The scene is attached as well.

By the way, there is no "Enable Particle Engine" menu item the options: http://prntscr.com/bcyjpj
Does anybody know what I'm doing wrong?

Thank you in advance!

Hey there! Thanks for the video and tips.
I don't know what I am doing wrong, but in Octane v3 I can't get to render particles unless I use a generator. Setting up the 'particle' tab in the octane tab in any way does not produce any result. So, how do you get the once called 'particle engine' to work on v3? i really can't figure it out.

Sorry guys,
To avoid this xp-madness why don't you download sample scenes from release topic and find the xparticle scenes? This is not so complicated. Just use Octane Object tag on xpemitter for direct particle generating or use standard geometry.
You'll need commercial version of xparticles plugin. Demo versions doesn't support direct access to particle data.

I'm having a similar motion blur issue with X-Particles.

I get motion blur okay in the live viewer. But when I go to render, there's no motion blur on generated particles if I've cached the X-Particles. If I don't cache the particles, I get motion blur rendered okay.

I 'm using an X-Particles generator with a simple sphere in it as the particle.
