Hello, I’m Ricardo Catarino (Portuguese), and i need some help on papervision for my School Final Project.
So, I m doing a website, and the navigation is the 3D object thet i import from swift3D to Papervision, in other words, i have a fantasy world(sphere Mesh), then 3 planes on it. And on those 3 planes, i want to insert the button. Then the Buttons will Load a external SWF or a movieclip.
Can anyone help???
By the Way i will leave the code down there.:mario:
The code works, but when i insert a button on the movie clip, he does’t load it. Bah…:crying:
Thx
