I would render out the 3D objects in two separate passes as PNGs or TGAs with alpha channels. One with just the building, a second sequence with just the debris, and then place them on two layers. Then drop the explosion between them.

There is a workaround, available in a video tutorial by Aharon here.

Are you using version 3 of particleIllusion, or SE? SE has limited formats compared to 3.0, but you can save out TGA files with an alpha channel (might not show up in the drop down as I recall, but it does work if you just leave it at the default and type .tga after the filename).

Try lowering the Emission Range, then adjusting the Emission Angle, and increasing the Velocity. That should push the particles more in the direction of the Emission Angle. You may find that you have to lower the Weight a little as well.

White on transparent is fine in theory, but the reality is that when Photoshop saves out the file, it will fill that transparent area with something. That something is whatever you have selected as your Background colour, at least as far as I know. So if your Photoshop background colour is set to white as you are creating a black shape on a transparent BG, it may end up with a very thin white rim around that black.
I’m not sure what you mean by image layer. Do you mean the particle types, images 1, scratches, splatter, etc?
I think the effect used to create those faces was Halftone. So greyscaling the image and then halftoning might do the trick.

You can export to any HD file size right now by using pIllusionRender, it’s included with particleIllusion (the icon is in the Start menu group with it). Just prepare your project at 720p, then open that file in pIRender and hit the Render button.

1. When you select a particle type in the Properties window and go to the Change Shape tab, whatever shape appears automatically in the right hand area beside the list of shapes in the library is the shape for that specific particle type (it’ll match the shape in the top left corner of the Particles tab). Once you start selecting shapes from the list, then you’ll only see the current shape for that type in the top left box, the bottom right box will display whatever shape you’ve selected in the list. So in the case of the HoloPoster, first select the ‘images 1’ or ‘images 2’ particle type in the Hierarcy part of the Properties window, and the faces will appear in both those boxes. The arrows below that image box will flip through the images that make up that type (they are a sequence of images, which are stored as one shape). If you wanted to replace just one of those faces with an image of your own, the best way to do that would be to save out the images (using the Export Shape button), then saving your own image with the same name as the specific face you want to replace (image_0003.png or whatever the case may be). Then if you re-add that sequence as a shape, your image will replace that chosen face.
That probably sounds a lot more complicated than it is. If it isn’t clear, I’ll see what I can do about posting a visual example.
2. To use multiple shapes for one particle type, you have to name the files sequentially, and then import them. Then check the Random Start Frame box, and move the slider below it from Fast to Off.
4. Was there any white rim around the logo at all? If you’re saving an image with an alpha, it’s always best to make sure the colour of the area surrounding the alpha is the same as the colour of the object . So if you’re making a chunk of white text, put it against a white background. It’ll be invisible to the naked eye, but when you select the text and create the alpha, that will be white on black, and you won’t have to worry about any edge bleeding that might occur.

Check to make sure nothing is turned off in the Layers window. Unless you have the emitters or particles hidden on a layer (either by turning them off in the Layers window or by clicking the star icon beside the emitter’s name in the Hierarchy window), everything on both layers should be visible.

The Dust Puff emitter from the March 2000 library is a good starting point. You’ll probably want to increase the Velocity and drop the Size a bit.
If you click on my head at the top of the forum, there’s a tutorial with a different approach to the disintegration effect that you might be able to pick up some ideas from.

It isn’t possible to change the colours now. The only thing I can think of that might make it easier is to drop an Increase Brightness emitter onto your footage as you work (it’s in the May 2001 library), and then delete it before render time.
