Object Shadows - and Shaders

[Mohawk20]

I made a lighthouse in 3DsMax, imported the obj in Terragen and placed a light in a sphere with a small hole, hoping the light would only come out on that side. However, the light just goes through everything...
Is there a setting I'm missing?

You probably have to activate 'receive shadow from surfaces' in the quality settings of the atmosphere node.

Dôh! Rookie mistake. Working with Terragen for more than 10 years, and then this!
Didn't use objects like this before though...

On the other hand, in a setting like this the glowing 'overpowering' effect is nice and more photographic than with all clean dark lines of the lighthouse structure.

i thought the same thing, maybe more samples/less noise...guess he wants a focused beam effect...

Well, I liked this as well, so I'm keeping it in mind. I'll do several finished renders some dark, some with fog, etc.
But I hit another bump...
In below picture you see the tower obj and a terragen cube shape. Both have exactly the same shader (the tower has the shader put into the respective object part node in the object shader).

Why doesn't the powerfractal pattern show on the tower?

You have to pull the PF through a transform shader set to world space.

Ah your best friend in TG3, the Transform Shader. I think the transform function should be available by default on all shaders. In Imagine3D the transform was globally available in every situation and without calling it into the stack,,,was just always there IIRC...been a while.
