I'm working on my monthly challenge image and I've got a little problem. I have got a terrain in my scene and I've got a lot of trees. I want to 'drop' these trees onto the ground but there are to many trees to do it by hand. Is there an easy way to drop them all to the ground? (the terrain is not flat so each tree needs to be at different y-codinates)

I've run into similar problems, and the best way that I've come up with - which is not necessarily THE best way - is to select them all - do NOT group them - then let Bryce drop them all by clicking the little down arrow. Each tree should drop to the terrain at individual heights. If you need to lower them farther, simply use the edit icons to drop them into the ground and hide the roots.

Okay. I'l try that. Is the function stable enough to drop thousands of trees at the same time? (replicating large numbers of objects can make bryce unstable so I thought I'd ask)

The answer is... no. I've tested it with grass, not trees, around 1000 grass blades of 8 polygons each... it does not work very well. When you drop to ground, half of them go underneath the terrain. The only solution I found was to select around 100 grass blades at a time and then drop them to ground. Make sure that your ground is not locked before proceeding.

Why not RAISE the ground? The Bryster

Well, there's this little feature. But, if the terrain is below the horizon (negative on the Y scale, it just snaps to 0y. Also, you'll need to push the roots below the ground a bit (or raise the terrain a hair).

COOL!!!! Thanks John!!

Nice find, johnpenn... never run into that before.

Thanx for all your help. I think I've got it now. At first it din't work, but I had the terrain below the horizon (as johnpenn suggested). I've succesfully dropped 267 trees to the ground now. only 2000 to go (LOL). Can anyone tell me what Anchor-Based Aligning is? (I'm too lazy to read the manual)

Thanks a bunch, I have wondered what that button was for. I don't have a manual.:(
