Having only played with EnvMapMaterial superficially, I’d also like some elaboration on this. :D

Hi,

I have been experimenting with this example and noticed something weird. The spheres with materials attached that are based on EnvMapMaterial have their lighting / material mirrored on their surface (as if there is a light source opposite the actual light source). The Flat- and Gouraud spheres behave as expected, but materials based on EnvMapMaterial show this fenomenon.

Papervisions’ EnvMapMaterial has a property .backenvmap. This property is utilized in EnvMapMaterial.drawTriangle but the implementation seems incorrect so that the backenvmap is actually never used???

The method seems to choose between the map to draw from (lightMap / backenvmap) based on the angle of the face with the light source. For angles > 90 or 0){
useMap = _lightMap;
}else{
useMap = backenvmap;
}
graphics.beginBitmapFill( _lightMap, transformMatrix, false, false);
[/code]

Would this be an explanation for the fact that materials based on EnvMapMaterial show this 'undesired', at least by me, side effect? As Im kind of a novice to PV I cant image that this wouldnt have been noticed yet...

Coudl someone confirm, or deny and explain?

I have a question about ShadedMaterial, why is there some black lines on the top of the sphere?
Can we remove it, how?

looks like the newest version of great white (pv2 beta) doesnt have “FreeCamera3D” but you can use find and replace to change the 3 instances to “Camera3D” and get the same results.
