Glass material with illumination?

I am planning to make a boat in a winter scene with lumion if what I need is possible.

So like the topic, is it possible to have a material behave like glass with the reflections etc but with added illumination on it, to fake light coming out from a room behind it?

Also, as a side question.

Is it possible to have a better res sky? In my tests the moon is really pixelated, and I want the moon in my shot. Does that get better with the full version? One would think that when you wrote your output that the pixelated moon would get better, but in my tests it stays just like it is in the editor?

You can make the Glass Material self illuminate by using the Overbright slider (RGB Tab) to set a value - to see the slider you need to hold down Ctrl key.

The more illumination, of course the less effective transparency.

If that does not work for you, then placing a spotlight in the room will give a cast light.  

If  however, you are after some sort of volumetric light (as in the God Rays Effect), then there is nothing within Lumion currently to provide for that.

re Moon: Render quality is the same for all products of a current version.  It does render nicely using Photo Mode or Video Mode (Single), but yes, you are correct, in video and Images the AA does not appear to be applied to the object when render Quality is set to 3 Star which should apply 16 AA.  

Thanks for noticing.  :)

edit: Please see Morten's reply, using the HQ Clouds in Render set to On to also render Moon and Stars.

Thanks for the fast reply. That helps a bit.

Another question:
 I'm trying to fake foam behind a boat, and putting a mesh beneath the water surface so that the ocean shader reacts to it and makes white foam seams to work. But this only works with some of the shaders you put on the object you put beneath the surface. Is it possible to make the "invisible" or "water" shader to react to the ocean shader the same way the other shaders does in regards to the foam that gets "created"?

No that's not possible.  If it's Invisible, it's not going to react (and doesn't), there's also no water to water/water behind water type combination.

Which version are you using?

You may have seen this work done by Byzantos on Ship Wakes.  Static images works OK, animation matching to the Ocean is a completely different requirement, and so far wake objects/rendering has been outside the goals of development items for Lumion.

Yes, you need to add a Cloud effect and set it to "HQ clouds in Movie render (Slow)".

It's not particularly user-friendly to place it in this effect (and call it that) as it clearly affects more than just the clouds :)
