Re: Models not showing up
Thanks for all your responses.
When I initially had the wheels as children of the car body, I could not get them to spin around the right pivot point. This is the reason I import them separately into my Vizard script. Is there a way to easily fix this problem.
Also, here is a trimmed-down script that I'm running....sorry for the length.
import viz
import math
viz.go()
def playAnimations():
#Add car and its wheels
Car = viz.add('Car.obj')
Car.scale(0.305,0.305,0.305)
Car.visible(viz.OFF)
CarwheelRF = viz.add('Carwheel2.obj')
CarwheelRF.scale(0.305,0.305,0.305)
CarwheelRF.translate(-0.92,0.35,1.09)
CarwheelRF.visible(viz.OFF)
CarwheelLF = viz.add('Carwheel2.obj')
CarwheelLF.scale(0.305,0.305,0.305)
CarwheelLF.translate(-2.379,0.35,1.09)
CarwheelLF.rotate(0,-1,0,180)
CarwheelLF.visible(viz.OFF)
CarwheelRB = viz.add('Carwheel2.obj')
CarwheelRB.scale(0.305,0.305,0.305)
CarwheelRB.translate(-0.92,0.35,3.45)
CarwheelRB.visible(viz.OFF)
CarwheelLB = viz.add('Carwheel2.obj')
CarwheelLB.scale(0.305,0.305,0.305)
