imported 3DModel - Color Write - Problem

[farshizzo]

Your model seems to work fine for me. Here is the script I used to test it out:

import viz
viz.go()

viz.add('tut_ground.wrl')

model = viz.addChild('testtree.lwo')
model.drawOrder(-1) #Ensure model is rendered to depth buffer before other models
model.disable(viz.COLOR_WRITE)

import vizcam
cam = vizcam.PivotNavigate()
cam.centerNode(model)
cam.setDistance(model.getBoundingSphere().radius*5)
cam.rotateUp(10)

Cool it works now.
Thx
It was the "node.drawOrder(-1)" line what made the difference.
what does this exactly do? As a newbie I do not really understand why it is important that the model is rendered before others....
for the future - if i load more of these specific models do they all need this specific drawOrder function???

Anyway, thank you very much helping me at this problem.

The object you want to have occlude other objects must be rendered to the depth buffer first. The default draw order of objects is 0, so setting the draw order to -1 ensures it is rendered before other objects.
