Emitter Boom 3 1 advice

[Renton Maclachlan]

Greetings

I’ve just upgraded to PI 2019 from SE. I haven’t used PI for quite a long while and have been playing around with it to get an effect I need.

Specifically, I’m using emitter Boom 3, with the ‘shape’ set at point. At the moment the ‘explosion’ smoke etc, spreads out from the point about 200 degrees. I want to be able to vary this, say set it anywhere between about 90>160 degrees. I can’t for the life of me find how I can do this. I assume it is possible. I can swing the direction of the ‘explosion’ around the ‘point’ but can’t see how to constrain the angle of the explosion. The explosion is to occur at the base of a cliff so needs to be constrained somewhere between about 90 degrees and 160 degrees.

Also…I have also just upgraded to Vegas 16, but find that using PI on an event crashes Vegas, at least when I try to go back to Vegas after working in PI. It’s happened about 6 times or more.

Edit…Actually I produced this Boom 3 effect mentioned above, way back in SE days, and now I can’t even reproduce it in PI 2019, starting from scratch!!!

I would like to have more detailed instructions on how this program works.

I’m taking the SE file and then just changing one parameter to see what difference it makes, but have so far not been able to work out what each of them do! And then key frames get inserted, how I don’t know, and that affects the affect.

I am flying blind…

If I understand correctly, you’ll want to use the “emission range” and “emission angle” parameters for this.

You didn’t have super emitters in SE, so not surprising that this more complex is hard to understand at first.

BTW, email me directly and I’ll get you into the PI beta program — I suspect any crashes you’re seeing have been fixed in the latest builds but it would be good to test!

Thanks for your reply Allan.

I’ve been through all the parameters, changing them drastically one by one to see what affect they have. So far I can’t see anything that constrains the angle of emission. The parameter ‘Emission angle ‘ changes the direction of emissions but does not constrain them within a particular angle.

In terms of Boom 3, I also haven’t found a parameter which can lessen or intensify the flash at the start of the sequence. I don’t know where that hides.

I did discover in Boom 3, under the ‘boom-line’ parameters, a list of ‘debrie’ (thought it was spelt debris ☺ ) parameters and was able to tweak those.

What I am trying to achieve is the burst of a shell landing. I just about have what I want but have no idea how to reproduce it from scratch. I don’t remember how I got to the the basic form I have now. All I’ve been doing since getting 2019 is tweaking a previously saved file…I think probably made when trying out PI3 during a trial period.

I’ve taken to using PI as a stand alone…which unfortunately does not have render capability at the mo…but that way I don’t have the grief of Vegas crashing. I can locate the effect in Vegas with pan/crop once rendered to an empty event…

I have PI 12.0.4, which I take is the latest release.

I have sent log files to Joe Kozenko re Vegas crashing with PI…

Not sure if I’m necessarily the best for going on a beta program…

Thanks and all the best

It’s emission range that restricts the “spread” of emission.

Did you download all of the additional emitter libraries? There are some good shell burst on the ground type emitters ready-made for you. From the PI UI, check the “Help” menu and then “Download Emitters…”.

After you have them installed, look at the “Explosions” library. You could try searching on “Hit” too, but browsing manually might be best.

Yes, I have all the emitter libraries…and have been through ‘explosions’ to see what’s there…boom 3 seems the best at this point, I’ll have another look.

Just crashed Vegas trying to bring my PI file into an empty event…

Just crashed Vegas again…and again…

So…I start an empty event on the Vegas timeline. I hit FX and choose Particle Illusion. I then Launch PI from the Video Event FX dialogue. I open my file in PI and the effect runs on the stage. I then cross back to Vegas and get the rotating arrow. As soon as I click in Vegas it greys out – not responding…etc… and so on…

Can’t get my effect rendered. I got another effect into Vegas and rendered. Why not this one?

I thought that maybe if I started a new project in Vegas with only an empty event in it, then add the fx, it might work.

It didn’t…neither in v16 nor v15…
