Hi Gap,
I've tested again.
The topmark now looks good (and rusty)
The icon on the map needs a severe talking to
IMHO it should be a lot lot smaller.
The lighthouse/rock alignment is still out. If, in the rock dat file, you bring in the lighthouse file using s3Deditor, align the rock under the lighthouse using the translation values, and then delete the lighthouse node from the rock dat file and save, would that not align things - this has worked for me in the past.
The sub treated the rock like a Mcdonald's I'm afraid - complete drive through
thats the tailend of the sub sticking out the rock in the screenshot.
I'm not sure about the caustics - possibly OK as there are shadows etc depending on where the sun is - would need Kendras' ( or somebody who knows about caustics) input on this.
My own thoughts about the reflection is that it is far too faint. It can hardly be seen and the light house looks weird on the sea - sorry. see my last screenshot of a L/H I imported from Sketchup and put on your first rock.
Kind regards,
MLF
