Sky blending...?? suggestions?

[k_iwan]

Hi

I was just trying out a transitioning sky from morning to noon skybox, and apparently, the blending texture method does not work for skybox.

################################################## #
import viz

morningSky = viz.add(viz.ENVIRONMENT_MAP,'morning/morning.jpg')
noonSky = viz.add(viz.ENVIRONMENT_MAP,'noon/noon.jpg')
eveningSky = viz.add(viz.ENVIRONMENT_MAP,'evening/evening.jpg')
nightSky = viz.add(viz.ENVIRONMENT_MAP,'night/night.jpg')

skyDome = viz.add('skydome.dlc')
skyDome.texture(morningSky)
skyDome.texture(noonSky,'',1)
#skyDome.texture(eveningSky,'',2)
#skyDome.texture(nightSky,'',3)

blend = viz.add('multitexblend.fp')
skyDome.apply(blend)

blend.param(0,0)

slider = viz.add(viz.SLIDER)
slider.translate(0.5,0.1)


def myslider(obj,pos):
if obj == slider:
blend.param(0,pos)

viz.callback(viz.SLIDER_EVENT,myslider)

viz.go()

When I run it, all i get is black. If I take out the blending part, I can see my skies. So, I guess the only alternative is by generating a 360 panoramic images and apply it on a polygon sphere? Any suggestions? Did I do something wrong?

Kind Regards,
Iwan
