Good,
bryce supports this method well. This is for the nonkey characters, like extras in Hollywood. If there are going to be a number of figures in formation Outfit and render one figure of each needed pose. Render each of them either individually or in small groups. Depending on your scene you could do that rendering in
Poser or
bryce. It is better to make oversized renderings of these figures. You will need to save these to disk with an alpha channel or you will need to prepare a transparency mask for each one. They need to be aligned with the camera as they will appear in the final scene.
Building your scene, create a 2D picture object for each of your prerendered figures, use the rendered images for the diffuse and ambient maps. If you prepared sepperate transmaps, use the transmap for transparency. Set the texuring mode to "blend transmarency". You could also create and use bump maps for a pseudo 3d effect. Now place your figure. Replicate it and place it where else you may need it. If you need to produce a number of them in formation, use multireplicate and the perhaps the randomize settings from the functions. Repeat with the rest of the pre rendered images. Make certain that they all face dead on into the camera, or the illusion will fail.
Then add your foreground figures as you normally would.
As for using P1 and P2 people, I was thinking of the nude one with props added for clothing, armor, and weapons. In a project that I was woking on before I pause it in favor of the images for the valentine's day exhibition, I was going to need a large number of figures like this also. Fortunatly most of them are in the distance and are in formation, so I started using the
Poser one males this way.
Poser 1 people a very low poly count models, rather ugly, but in the distance they can be useful.
