ok, heres the problem, I need a hole, booleans are supposed to make holes....well, I set one object (A mountain in this case) as positive and the other (The hole I want int he mountain) As negative, but when I apply the textures and posistion them, I get this nasty looking square thing (The base of the negative objects' terrain) smack in the middle...

I need a nice clean hole in my mountain, how do I do it?

you ARE grouping them aren't you?

One thing you want to make sure of is that the mountain is "Solid." When you go into the terrain editor, you click the downward arrow at the upper right-hand corner of the editor to make sure "Solid" is checked. burgi also made a good point. Unless you group them, you'll have nasty primitives jutting out of nowhere.

Of course I'm grouping them (I may be new to booleans, but I aint stupid...)

well check the solid thingy. jus' checking you understand, it took me 3 months to realise you had to group the buggers.

hehe, ya I grouped them, It might be the solid thing, I'll go try that...

For object 2 (the negative one) try using a lattice rather then a terrain, mean no square base!!

arg, now I have a new problem I cant line them up properly :( bryce's interface is mean to me

Booleans do weird stuff anyway, especially when you try to combine two 2D objects like a plain or terrain with a 3D solid. Try a Bryce rock instead of a terrain to make the hole.

After you've grouped them have you checked intersect in the attributes box? If you don't nothing will change. Catlin

Here you have both vertical and horizontal negative cylinders creating holes in a positive terrain. Materials transfer from the boolean object is turned off. If you followed the steps correctly, including grouping the positive and negative objects together the process should work. If it doesn't, I suggest you start from scratch. Perhaps you duplicated the terrain unknowingly. That would cause a problem like the one you're describing. Good Luck! : ) (PS- Make sure that the negative shape is large enough to extend entirely through the positive shape)

Nuski has a point, Although, I've had trouble booleaning terrains before too...

I had the problem Nuski mentioned and it took me days of redoing to figure it out. Make sure your negative shape extends fully through the poitive shape, at least on one side of the terrain anyway if you don't want it to go all the way through. This hole was made with an odd shaped rock,you can see where it does and doesn't extend through the terrain.

poitive= positive

it would be nice to press a key combination to turn the cursor into a little stick of dynamite then where ever you click in the scene it leaves a ticking bomb which blows holes in everything. in realtime. great stress relief idea for when bryce has nosedived for th 13th time. John

nah..Mac's already use bombs for error messages...;) thanks for the info, guys..there's always something new to learn..;)
