Only Forward and back

Hello guys!
I have an issue. I want to parent a sun lamp to an object which can move and rotate. But, i’d like the lamp only can move forward and back, but cant rotate. Is it possible? I tried everything. Please help me. :slight_smile:

Use vertex parenting to a single vertex. This will inherit the location transformation only.

Thnaks a lot. It helped me. :slight_smile:
