I'll give it a shot. I'm a-thinkin' image bit depth may be an issue, too. And yeah, the appropriate checkboxes were checked. Back to the salt mines...
Thanks for the response. I'll let you know how it works out.

It should work the same way, so I guess your opacity mask is not correct, or you didn't check the 'use alpha channel'. I always work with a tif with a black-white alpha channel, which works perfectly. I believe some use a transparent tif or png, but I don't know how that works (as opacity is off, or on - from 0.5 and higher).

I'm sure this has been asked over and over, so my apologies.
I'm familiar with using opacity/transparency masking w/ the micro-poly render. No problem. But for some reason I'm unable to come up with a way to get the same thing to work w/ raytracing. The leaf color images appear but is surrounded by the remainder oi the texture rectangle - the black square phenomenon.
Any hints would be greatly appreciated.
TIA -

Interesting...and thanks for the feedback. I tried adding a tag with a leading uppercase letter and the tag saved properly; even closing and reopening the Library. I also tried a leading empty space, and that worked as well. I wonder if there's a special unseen character in the tag you were creating?
It would be good to know which version of Terrgen you're running and which operating system too.

To achieve good results, you always have to fiddle a lot around these and that, especially colors.
Your colors are great, they look very natural!
@ Dune, thx for your example!

Thanks very much for that example Kevin.
When I copied what you had done, it worked, so it made me realise that I was putting a capital letter in at the start of the tag, and it looks like it doesn't like that. If I use all lower case, it works. That will make life a lot easier.
Thanks for your help, much appreciated.
Rob.

Yes, I applied a tag to a TGO formatted object and it works as expected. I also exited the library and shutdown Terragen and restarted it, and the tags were still there.
What version of Terragen are you using?
Here's a screen shot of what I'm seeing:

Thank you very much for the valuable tips. I will apply them to my next pictures.

Yes, sphere works better than lake. You can raise/lower water level by putting the water shader as child on an empty surface shader and use offset.
My example was very basic, just to proof the simple principle. I guess for a 'similar' result you should add the color stack you had and thicken the default shader masked density, or take the reflection down (or translucency), and perhaps raise the murk more (and maybe use unclamped color to displace, not an internal displacement, which also displaces downward).
