Wasn't really my idea, but Doug's (Zaxxon). TG needs FBX, so it seems. I probably agree 

There's no alpha channel in the png, period. So it eludes me. But I'll use TIF+alpha from now on, just as easy.

when I've had a problem with an Alpha channel in either .tif or most commonly .tga, I load it into Irfan and re-save as a .png selecting the background colour as transparency, and an image saved like that always shows an Alpha in TG. But that's just my work around. I have had a few .png images over time that had Alpha functionality but did not show the Alpha in the preview image...guess that  is what you ran into.

As it looks you have transparancy in your image Ulco.
Maybe it is this? :

" Transparency control is also possible without the storage cost of a full alpha channel.
In an indexed-color image, an alpha value can be defined for each palette entry.
In grayscale and truecolor images, a single pixel value can be identified as being "transparent".
These techniques are controlled by the tRNS ancillary chunk type.
If no alpha channel nor tRNS chunk is present, all pixels in the image are to be treated as fully opaque. "

that quite possibly explains the .png...thanks for the info.

Kadri, that's probably it. And in the screenshot it shows the checkerboard denoting a transparent area. Terragen just sees an alpha channel after loading the image, but it doesn't really care whether it was read from an actual alpha channel or generated from some other representation of transparency.

Thanks a lot, Kadri. Why didn't I think to search for this information? Good lesson, and good to know.

By the way, great image, Ulco!! I don't know, how often I wrote this, but I would have recognised your image as an original "Ulco", even without knowing it. You have a very unique style!

This will be a sequence of 5 over 10.000 years or so, exactly from this point, so it'll be nice to fade them over.
