how can i get particle motion blur based off the camera motion?
im using vray camera to control depth of field, but cheking the motion blur on vray camera doesnt give any motion blur that the motion of the camera in space in relation to the particles would give,
i guess the standard camera would work as it does many passes, that one doesnt allow me to animate depth of field! 
any suggestions?`
Enable Krakatoa Motion Blur?
It will render the particles in multiple passes (even of the particles have no Velocities) and if the camera is moving, you will get motion blur from that. This method is faster than Camera MultiPass Motion Blur because it calculates lighting just once per frame.
ah ok, i tried that but didnt get anything, but didnt try raising the shutter high enough to see something,
would it make sense to seperate camera and velocity blur in the future?
because when raising the shutter high enough to see the camera mblur, the particle velocities in certain scenarios are way too high
it would be nice to have control over each seperately
Actually, you have some ways already.
You can add a Global KCM that scales the Particle Velocities any way you want to increase or reduce the particle motion blur without affecting the camera motion blur which uses the Shutter Angle.
jea i thought of that too, ill reduce the velocities in magma!
speaking of which,
i wish the preset library would grow some more! any interesting flows u might like to share?
Interestingly enough, I enjoy wiring stuff in MagmaFlow so much I tend not to save anything and recreate flows from scratch each time I need them. So I donāt have a cool library to share, but a lot of knowledge I could share if I had the time. It is the same with scripts - I have more knowledge of MAXScript than an actual library of scripts. When I need something, I write it from scratch and it gets more polished every timeā¦
hah,
well, to put it mildly, you would do me and probably alot of other people a huge favor by saving out those flows and making the magmaflow library grow! 
i think there are many artists like myself that are not very good in any type of programming, or wiring, i have already gone far with box3 (for my own little standards) but really the more āpresetsā there were for all these amazing tools the better i would better be able to understand them, and modify them to my needs, sculpting to have it do what i like, but creating these from scratch often seems very difficult at least for me,
i personally think the krakatoa and cg community could benefit alot more from these libraries, just like the box3 operator barter hall could grow some more, i understand that one doesnt want to share everything, which i totally respect and some things i would not want to share myself, but often there are hidden treasures waiting in little setups, waiting to be discovered, some of which another human might relate to in a completely different way and come up with something totally amazing, which in effect could inspire the author of the preset used!
not only that, it would help support the software and the community that uses itā
magmaflow has gotten little attention by me and has staid untapped for most of the time, which is a shame because i know how powerful it is,-- im happy when i am able to multiply a velocity!
i will speak no further and upload this week the presets with the magma flows i have made to give what i got! (most of them were created by your help or the documentation :p)
SPREAD THE LOVE 
I go through this all the time myself. Constantly redoing the flows, tweaking and polishing each time. And Iām stuck between the idea of āIf I just Blop these, other people in the company can save time tooā and āIf I just Blop these, other people in the company will never learn how to make KCMs.ā Itās a constant battle. Especially since they arenāt compiled down to anything, and people really DO need to learnā¦
sharing information encourages learning. 
and maybe you would learn something by what someone else does with a flow youve made.
every artist has different potential and a different perspective.
i think it would be encouraging to see more magma flows by the technical krakatoa experts, and even as part of the support of thinkbox and tutorial documentation it would make sense
my 2cents
i can happily make a location for magma flows on the website if people want a location.

We have this place here on the support forum which was meant for posting presets, flows etc.
viewforum.php?f=56
that would be great chris!

Bobo: yeah, but its never as easily accessible to those who dare not venture into the forumsā¦ we should put it in downloads, and start by duplicating what is here so people āseeā it.

Aye aye captain! 
Just make sure you link back to the forum! We need to encourage people to come back here, and it will prevent issues with stuff being out of sync.
