Hello!

Look at the picture.


I have a problem with the direction of this IES light.
If I rotate maps or the emitter face the IES direction doesn't change and is always 90° from steps line.

Any suggestion?
Thanks

What is the IES applied to?
Which maps are you referring to??
FYI you should apply the ies to a sphere and simply rotate the sphere to move the light.

Sphere or face is the same.
This is the scene http://we.tl/YU176ssMDe

By rotating the sphere the emitter direction doesn't change. Rotating texture mapping doesn't change... what else?

(I used archicad to model the scene)

Thanks!

Hello Federico,

It was just a pivot issue.

When I've opened your scene, I noticed that your emitter sphere has not its pivots point in its center, but is someplace else in the scene, causing that you couldn't get the orientation you where after.
I simply centered the pivot (by hitting the "Center" option in the sphere object panel) and once with the pivot in the center of the object I was able to rotate it and get the desired orientation of the IES bulb.
See test render below.
In addition to that, I strongly recommend you to use an smaller sphere object for IES (ideally a point light).

Let me know if this solves your query.

The test render

It works. Thank you!
The only matter is that I have 20 steps so I was looking to a way to do it in Archicad.
