Anyone have any luck performing boolean operations on trees? -Brian

Love to use one of those "Lumber Jack" chainsaw...let me at it! };->

Tesign, I haven't tried that, must try that tonight. Do you Boolean one tree with another tree or with primative? Sharen:) PS: have you tried it?

Well Brian, the answer is yes and no - lol. Yes it's possible to use Boolean operations on the trees, but it's very unpredictable as to what results you may get. I first tried this when I was creating a window scene, with a tree outside the window. To get the tree looking right, many of its leaves were hanging to the inside of the "house", coming through the wall and ceiling. So, thought I, I'll just Boolean substract those stray leaves from the rest. I performed the operation using a cube, and the leaves remained but the tree trunk vanished! =:o What I ended up doing was "squishing" the tree so that it could retain its height, but no leaves were pushing through the wall any longer. Booleans on SolidGrowth is like Booleans on terrains -- very unpredictable. You may or may not get what you're seeking. :)

Sounds like the normals are facing the wrong way. This may sound goofy - okay, it is goofy - but try Boolean Intersection or Boolean Union. In Rhino, if one object has the normals going the wrong way, you get strange results with Booleans. Before I figured out how to change the direction of the normals, I discovered that sometimes a different Boolean operation would give me the results I wanted - if not the ones I expected. See if this works. I'm kinda curious if I'm right. :-)
