camera motion blur with particles problem

[Morbid Angel]

maybe post the scene with blob mesh particles only so we can check it. I can collapse mine no problem.
below is two images, one blob mesh as you can see not blurring, two is blobmesh collapsed to poly.

great..i think that will work if i can get them smooth enough with a meshsmooth or relax modifer as suggested. super....

I think I will have the same prob though when i do the water effect (ie splashing and hitting the bottle). those will prob be blobmesh too and i can collapse them since they have to deform...(sigh)...but at least i have a solution for the droplets on the bottle! thanks everyone! appreciate all the advice

[Morbid Angel]

yeah...for more complex water sims i would suggest realflow, it supports motion data, which can be motion blurred by vray.

[highpoly]

Thanks Morbid Angel...
For the sake of time I wont use Real Flow this time, since it jsut a real quick splash... Also, i was doing some searching in the threads about 'affect shadows' on/off in an effort to understand them and came across your thread below

http://www.chaosgroup.com/forum/phpB...affect+shadows

Great examples! So basically Affect Shadows is a quick way to get light to pass through a trans material. If I want real caustics, then i have to turn on GI caustics and QMC/LC right? Wont IR/QMC work too for that? or do i need LC? I use IR/QMC
a lot..is that not good setup for doing glass/water in product shots with animation?

[highpoly]

oh! forgot to add...does 'store with IR map'ON in vray lights make any difference when it comes to making GI caustics? I know it speeds up shadow rendering but does it affect the caustics? Obviously you dont want it on if using QMC/LC (no IR map)...

Since I do mostly animations, i leave it checked off since there seems to be a lot of shadow flicker/blotchiness ...

[DaForce]

highpoly, I would suggest for caustics you use the links I gave you in your post about the flickering problems. They will be quicker than Morbid's method mainly because you dont need to use QMC/LC which is rather slow, and for the reason I mention in your other thread.

[highpoly]

hey DaForce hows it going? yes, someone please tell me boss to stop bothering me with work so i can do some research/tutorials!! lol

I will definitely take a look and check back in..

here's how the bottle is coming so far (sans blur and droplets)

some spin, blur and droplets and we are good to go!
will post my blurred droplets results from the blobmesh, seem to have digressed from my original topic (sorry!)

[DaForce]

Hey mate

Bottle is looking really nice!!

Mind you in a render like that caustics basically wont be noticed. In your pourring one however they definitly will be.

[highpoly]

well, here is a shot of the drops with blur...I know in reality that a bottle spinning that fast the drops would fly off but you never know what a client will want, no?

Here also is a render of the product shot. The client took away my nice dramitic lighting so I had to light it more flat, sigh (oh, the name is more important?) But having refractive drops intersecting with refractive part of the top of the bottle was giving me render nightmares (had to keep upping the depth of reflect and refract for both drops and bottle to get rid of nasty black). So i decided to just make the drops invisible to the bottle's reflect and refract. now you cant see the drop through the bottle on the other side, but considering they looked distorted and distracting anyway, plus render times went down 400%, i think in the end its a good quick way to do drops that intersect a ref surface.

comments? drops look OK or too clear?

thanks for all the help guys...
Now on to caustics training

[DaForce]

Looks good man, drops look quite nice!!

Caustics training hey.. enjoy
Let me know if you need any help
