Hi Team,

Can someone please clarify the way normal maps are handled in Broomstick?

To find out which colour channel is used for which axis, I did a very simple experiment, but with rather unexpected results.
http://www.videometry.net/broomstick/normals/NormalsEx.html
The normal map used, show in the top left corner, is created in Prefab from a sphere.

Digging into the Broomstick examples I found the LightingTest used normal maps, but they are of a type relative to the face, rather than the world coordinates. Applying the world coordinate normal map from the head example produces the same effect as in my example.

Is there a way to switch between using world coordinates and face coordinates?

Any help about the normals implementation in Broomstick very much appreciated

Cheers,

Pete

Any word from the devs on the Normal map implementation in Away3d 4.0?
Currently it seems to be a NormalBump map instead, i.e. relative to the face, rather than the world coordinates.

In other words, no longer able to do this…

Having both would be so very beautiful
