thanks for the comments folks
so my next scene involves the deck of the ship - the captain barking out orders. I want the deck to look like its populated with a lot of people - but the problem is if you have too many characters in one scene, iClone (more likely your PC) starts slowing down, gets sluggish and non responsive - so how do we solve this problem?
The BILLBOARD PROPif you look at SET - PROPS you will see the BILLBOARD prop. The BILLBOARD prop is basically a plane that always faces the camera so no matter what angle you look at it, it ways faces you
The PREPARING BILLBOARD AVATAR
Notice the BILLBOARD prop has 0 polys so it is ideal to use as a proxy for a real avatar
1) to create the BILLBOARD prop, follow the steps below
in step 7 above, why did we change the background color to BLACK? well because it blends better to the background, you can leave it white but the edges will stick out in a dark setting so i always opt for black. So we have two pictures we've exported - one with black background and another with white background - the white one will be used to create the opacity map - it is much easier to do this if the background is pure white
Additional tip - you can change the face, or the pose and export 2 files for each change (1 black, 1 white background)
2) Open up your photo editing software and convert the picture with the white background to an OPACITY map (i.e. the avatar white and the background black)
3) you should now have an opacity map that looks like this one
ASSEMBLING the BILLBOARD AVATAR
4) now lets go back to the scene - we will import the set (in my case the Galleon) and one avatar so we can judge the sizing of the billboard prop
Follow the instructions below
5) Use the Modify controls and import the DIIFFUSE map (picture with black background) and OPACITY map (the map we created at step 2 above)
6) use the MODIFY - TRANSFORM controls to position the prop near the real avatar and resize the prop to match the real one
7) once resized, save the prop under the CUSTOM _ BILLBOARD tab and name it CREW1
8) Now import the prop as many times as you want and position them appropriately in the scene. As mentioned before, if you prepare props of different faces, poses, it works more effectively. In the scene below we are only using tow real avatars others are BILLBOARD props
Adjust the set lighting as needed. Note these props do cast shadows as well
Additional Hint - if you want to save time, you can merge the Billboard props so you can import a bunch at a time next time you want a crowd scene
Here's an example of how i used merged billboard prop to create this 'army'
