Changing Framesize & “Slow Motion” ?
Hi!
I’m very new to particleIllusion, so probably some of my problems seem to be stupid to you, but anyway, I hope you can help me. Many thanks in advance!
My first problem is the Output resolution:
I read somewhere that particleIllusion can only render what it sees. So, is it possible to render something in HD resolution (e.g. 1920×1080 pixels, that’s more than my monitor is able to display)?
And my second question is about speed:
Is it possible to change the speed of a whole project, so the result is some kind of slow motion, without changing each emitter? If not, how do I slow down the emitter, if they depend on the emitting speed? I’m using some emitter with particles, which expand first and then fall down (according to gravity) but if I slow them down with the speed curve, they won’t expand anymore, they just fall down.
I hope you can help me with my problems. Many many thanks!!!

There is a special renderer for particleIllusion 3 that can render at higher resolutions, but the downside is that it doesn’t use open GL. It is free to particleIllusion 3 users only – it won;t work with other versions:

As far as speed goes, it depends on what you mean.
Certain effects can be slowed down by playing with things like Velocity, weight, size over life…etc. However, What I like to do to create slow motion is something like this:
Change the frame rate to something like 240 FPS (8x the normal frame rate), scale any emitter keyframes up by 800%, and then render out the effect as an image sequence (TGA, PNG, TIFF).
Then I bring the footage into after Effects and tell AE to read it at 30 FPS, which means AE plays it back at a normal frame rate, thereby slowing the whole thing down.
I’m sure that this method will work with any video editing package that can read image sequences. Heck, even if you have no video editing software, you could re-import that image sequence in to pIllusion (with the project set to 30 FPS) as a BG movie, and have it render it out again as an AVI at 30 FPS…
I’m happy to explain further if you need it, but since I’m in the business of selling myself, I’ll also mention I have about 20+ minutes devoted to this very subject on my DVD, particleIllusion Fusion Volume 1:

Hope that gives you some ideas.

Great! Thanks! Everything in slow motion now =)
By the way I noticed that I’m using your Debris01 Emitter for my animation, thanks for the great stuff.

Glad it worked. I want to point out that when using this method, the issue’s that pop up from using an image sequence, like in my debris emitter is that the rotation of the debris (which is a moving sequence, not just pilluison spin), ends up playing too fast. It’s not that it’s playing too fast for normal speed, it’s that it is playing too fast for slow motion. They should be rotating really slowly, but they end up rotating at their normal speed.
If I were slowing the speed down to 1/8 the original speed (by changing to 240 FPS), then I would probably need to remake the 3D image sequence to be play 1/8 the speed.
It’s one of the limitations for slowing things down that this method has.
You could go into the emitter shape tab (properties) and slow down the sequence, but all that does it make the image update slower, which makes the animation look stepped and jerky in this case.
