Aaack Aardvark has made a nautic light that looks similar. Downsides: I don't know if it's still available in-world (I have it, though). And it's fully automated which means there's at timer script running all the time.
Thank you so so much! I searched with so many words for it, but found only 3D Models you have to pay for. Just upload inworld without error, and how cool: it has normal maps and all include. neat! Thank you!!! :-) xxx
I added another material to the light bulb, which was missing. Now it really looks cool with a bright light bulb. Thanks again. :-) If anyone want it: just send IM inworld (OsGrid)
