Hello there!

I tried to make an effect, but got many problems, since I don't know how to create an effect with glow and transparent background.

Anyway, I would like to offer here, an idea and request a special plugin.

I need the Ghostbusters Ghost Trap effect. Here is an animated GIF (with 700Kb) that shows the Ghost Trap in action.



Wait it to load. It will take some time, depending from your internet speed.

To copy this image to your hard disk, just right-click on image and choose "Save Image As..." and find a place in your hard drive.

If you need an AVI, MOV or MPEG video file, showing this scene with high resolution, let me know via e-mail (get it at my profile) or Private Message (reach this option in topic's bottom area).

I'll digitalize the sequence, create the video file and send it to you, by e-mail or send you the link to be downloaded by you.

If you could develop this plugin effect, let me know! I need it to my AlamDV and I guess it will be an AWESOME addition to worldwide AlamDV's community.

Thanks!

Presuming that you have a box to use as a prop (if not, you shouldn't be asking for a 3d object as a plugin) all you need is the triangular light beam from the box itself, animated to get narrower, then vanish down a line into the source.

The lightening effects round each ghost are already a plugin and obviously since the person who makes the plugin wil have no idea what shape or size your ghost are, they shouldn't add the lightening as it won't be configurable.

The glow of he box itself is just a case of using the lightbulbs plugin, and any additional lighting could, i'm sure, be created by putting a real life light bulb in the box prop.

Using the existing lightbulbs with some masking, you could probably create the light cone fairly effectively. That kind of thing will be a bit easier to do in AlamDV3, of course, as it shares Chromy's masking system.

Guys,

In fact we must discuss considering user HAS a real Ghost Trap prop. So, I'll not need the 3D CGI trap.

I'll try to report some details you couldn't see first time looking, because I was studing this effect for some time. So, I'll try to describe what I noticed in the effects, separating it as "layers".

The trap has a white triangle as it base beam. This is the "outter limit" of its beam and the 1st Layer. In its origin (where we see the prop trap), we have a very strong flash, like a very strong light lamp.

The idea to use a light lamp inside the prop and in the set are VERY interesting and I should try it too.

Over it, we find some Electric lightnings. The beams runs over the ghost and some runs random paths, from top to bottom, as being pulled into the trap. It runs in a random sequence.

As I know its impossible to make the ghost's lightning, since you don't know user's ghosts, I suggest you to discard this effect's part, creating only the random runners lightnings that goes from top to bottom and become smallers (like sucked bu the trap).

We can see some small energy balls, like small comets, running from top to bottom and in a "zig-zag" movement. These comets are about 35% visible and about 65% transparent.

All effects I pointed are in the image below, with arrows to be visibles.



Do you thing we can have this effect?

Thanks!

Mabye you should learn 3d and particles, and do it yourself.

I think you could probably do all of this as a physical effect (with a bit of CG lightning):

inside your box put a lamp with a cone around it to keep the light going up in the right shape.
To make the beam show up get hold of a smoke machine and but a thin layer around the box. Then have a strobe light going off and more smoke if you want. Then add in your ghost shimmers and lighting in alam.

Oh and enhance the base of the light with an Alam Lightbulb.

Well,

I guess it will not reach the effect we want. If so, why Ghostbusters staff didn't use this?

So, I guess we still need the Trap's effect.

Of course, I'm not discarding the lightning effects on set. Its as many important as the CGI's effects, but we still need them.

And a smoke machine will only work as you report if computer controlled, to keep the smoke running perfectly.

Again, the smoked scene will be very poor, in front of the movie's effects.

My opinion...

This is off topic, but AlamDV 3 can do all the masking that Chromy can do?!?!?!? eek If this is true i will be the happiest man alive!

I imagine most of the trap effect can be accomplished with some innovative use of existing AlamDV2 plugins. The only exception would probably be the ghosts themselves - but that's because they were hand-animated by the effects guys on Ghostbusters (like most of the effects, it was all roto animated - no computers back then), so unless you're willing to hand-animate in photoshop or something, you're only going to get an approximation.

Umm... ok, you don't have to do it exactly like the people that did ghostbusters did it. As an amateur/independent filmmaker, you'll find the way Hollywood does it is never the low cost way.

There is no right way to accomplish an effect. You can do it however you please. There have been some great explanations and techniques described in previous posts, and from the wording in your post, it seems like you're not even considering them.

Second, I really don't feel there is a need for two posts, posted at relatively the same time, about basically the same thing. One asking for the proton stream, and one asking for the ghost trap. Both relating directly to Ghostbusters effects. They could have easily been compiled into one post.
