I have a noise shader here but have a problem. The shader works fine on the object and the material preview is correct too, but the preview in the AM doesn´t work at all :
The problem is that I am using cd->vd->p as evaluation point of my noise function. When the AM preview is calculated though VolumeData doesn´t seem to be valid so I cannot use it.
So what I can use instead when vd is NULL?
Thank you

If you mean the (new) preview control then you probably should be asking this of sdk_support and not here

hi,
no I am talking about the preview in the AM that is in there since version 8. It´s under the texture group (that´s the name of the gui element I think...) in almost all channels.

cd->p is not a coordinate in world or local space but a  width and height value in range from 0.0 to 1.0.This value gives you a position on a 2d map . this is the map that you will see in your preview and render. So its 2D texure space and not 3d space.

all the more reason for a SDK conference in fc
