for loop concatenation for 300 billboarding trees

[eugcc]

Hi there,

I'm trying to run through a loop to billboard many trees in a landscape, instead of doing:

land = viz.add('landscape.WRL')

tree1 = land.getchild('tree1')
tree1.billboard(2)

tree2 = land.getchild('tree2')
tree1.billboard(2)

...

tree300 = land.getchild('tree300')
tree300.billboard(2)

Can I do a loop with something like this that will allow all the trees to be billboarded? But it wouldn't work:

for i in range(20):
tree = land.getchild("tree" + i)
tree.billboard(2)

I'm doing this because the billboarded trees in 3dsmax exported to vrml and into vizard wouldn't work.

Thanks in advance
