iwkya 61 posts05 Dec 2009Hey,
I have got a pflow system following a path, the system is great. But, when i apply glow via effects and render with vray it doesnt seem to render all of the particles, id say about 20% of them it renders. With scanline its works fine. Any suggestions apart from rendering the pass out in scanline hehe, i could use it rendered with vray,
Thanks -
05 Dec 2009Well I can't really help with your problem since I haven't run into it myself, but as a rule you should never ever ever ever ever ever do post effects within max. ALWAYS render out your frames and do things like glow in a compositing app

iwkya 61 posts07 Dec 2009Yea, was thinking of doing it in ae anyways, but now will defo. I do have another issue though if you can help. I have a bunch of particles looping around a spline. I was to render this out and loop it in flash for a site. Now, i had the problem of the fact that the start frame (were the particles are not emitted yet) and the end frame are different, so i looped it for 300 frames (100 full cycle), and rendered from 200 to 300, that way I got the particle stream already made by its previous frames. Thing is, even though the animation of the geometry is perfectly looped, the particle stream is never the same on the start of the loop. Any ideas how I could fix this ?

TheOnlyAaron 188 posts14 Dec 2009I have had to make loops like this in the past, mostly for animated textures etc. What I do is render out a section that is 2 times as long as i need, that has the full animation in it. So for you if you want a 100 frame loop, and it takes 100 frames for your particle system to complete it's spline path, then you would want to render out frames 100-300.
Now using a compositing program, I use After Effects, you will want to cut your animation into two sections of 100 frames each. Then layer them in your compositor / editor. Now take the one that is on the bottom, and split that in two sections of 50 frames each, and then flip their positions. If you loop those two clips, you will have a seamless edit at the loop point, and then have a break in the middle of your clip. This is where that second section comes in. Blend into the the second clip when the first one's loop point is. Because the two clips are offset, you will have a clean section to cover up your edit.
Hope this works out for you
