Hello RRMesiah
Very new to Terragen and skybox. One thing I wonder is whether I can use Ptgui to put together the images rendered from your Render Skybox app? if so, is there a way to do it,have tried, but the ground picture is distorted. I have tried to combine this tutorial with your app.

Yes you can. Distortion of images is usually a symptom of setting the incorrect fov or orientation of an image.
I use 90° tiles myself because they're quicker to render and you can feed them directly into a range of applications utilising "sky boxes".
The 2 critical settings for PTGui are in the Create Panorama tab.
1: Uncheck use fast transform. If this is checked you will see small black holes along the seam (especially in the corners)
2: Set the feather slider to the extreme left (Sharp). You have theoretically perfect images so there is no need to feather images at their edges. Feathering will create gaps along the seams as well.
[Edit] FWIW PTGui can also use Panorama Tools for the "rendering" (it was originally made as a GUI for Panorama Tools, hence its name) and the original version of this could also stitch images without overlap nicely. At some point in its life it appears that the developers who continued Panorama Tools also implemented a faster transformation to improve performance... good for stitching photographs, but it leaves holes in the corners in this situation
. A "few" years ago I used it to stitch and re-project rendered frames on the fly such as this 180° cylindical test:
