The space on a default value for a point parameter doesn't seem to be taken into account properly.
The attached example demonstrates the problem.
The scene contains three disks at positions (0,0,0), (1,0,0) and (0,0.7,0) (the latter is not 0,1,0 so that the disk can be seen properly).
The camera space differs from world space by (0,0,1).
The shader that is applied to the disks displays some points as colors. The points are the origins of the world space, object space and camera space.
The shader divides the disk into three "layers". The center is the camera space, the middle ring is the world space and the outer ring is the object space. Each ring is again divided into three sections that show the points from three sources:
(have a look at the shader, then I hope the description makes sense)
In the rendered image, the disks should all have a black center (as apparently, Aqsis is shading in camera space). The middle ring should always be pure blue because the origin of the world space as seen in camera space is (0,0,1). The outer ring should be colored with the position of the disk, so the middle disk should be blue, the right disk magenta and the top disk cyan (not pure cyan though).
The sections of the rings should not be visible because all three points that are used for shading a ring should be the same. This is where Aqsis fails. The points that are passed as parameters are as if they were described in world space instead of object space. Only the local variable is correct which means only the top right third of the rings is correct and the rest appears in blue.
I don't know if it's related or not but aqsltell also reports all spaces as "current" which obviously is not correct.
