Randomly and Continuously Change Avatar's Face Texture

[Karla]

Thanks for the suggestion. It works for quad objects but not for the avatar's face.

The avatar's face becomes blacked out when the texture is applied. There seems to be a difference between applying a texture to an avatar's face and applying it to other objects. I am having a similar problem as in post
http://www.worldviz.com/forum/showthread.php?t=776

Using 'texture.wrap(viz.WRAP_S,viz.REPEAT), texture.wrap(viz.WRAP_T,viz.REPEAT),' applies the texture correctly to the avatar's face. Therefore, it is not blacked out when using 'wrap.'

How can I incorporate 'wrap' with the random texture application? An error message said "'ActionData' object has no attribute 'wrap'."

Thanks,
Karla

Then set the the textures to repeat mode when you add them:

textures = [ viz.addTexture(f,wrap=viz.REPEAT) for f in files ]

THANK YOU! THANK YOU! That code solves what I want.
