Render Question with new Stair PIO

[Horst M.]

Hallo,

I recently created some simple Concrete Stairs using the new Stair PIO,

to try out some lighting possibilities for a Staircase.

When I tried applying the Textures by using the Graphical Atributes of the new Stair PIO I ran into some Problems which I couldn't solve.

The textures seem to be applied in Plane Mode to the Parts of the Stair.

This happens also, if I give the Parts a Class, and apply the texture by setting the graphical attributes to "Class Texture".

Is this a bug, or am too ... to find the right place to switch the textures to render in Cube Mode?

I attach a Testfile and pdf that shows what I mean.

Does anybody have a solution?
