sky textures help

[ak3221]

Does anyone know how I can fix this?

I have a few sky textures I like to use from the Redding route that do this too, while oddly, others display perfectly in OR. Always wondered what the difference was between them.
Curious to see further replies.

I'd be delighted to be proven wrong, but I think the answer is they can't be fixed. I had a week or so where I went nuts with sky textures and despite trying all sorts of options, couldn't find a way to make those "seams" blend in anything approaching a natural way. If you look at the night sky textures I uploaded, by making sure each side of the texture blended smoothly into the other 3 sides, I got a pretty good result for the night sky, but I couldn't replicate it for day time skies. The only way I could get it work was by having smooth/solid edges, but whether they were a colour complimentary to the clouds, or blue for the sky, it still didn't look right as the need for the "seams" to be consistent clashed with heavy, varied cloud cover and the various pieces of the skydome were still obvious. It's really frustrating as there are some great sky photos around, but unless they have minimal clouds, I didn't get close to a satisfactory result for day running.

If Robert is around and still working on the environment files, hopefully he could offer an opinion on if there is a work around.

Hi Peter, glad you didn't off the deep end during you trials with the sky files
I'm simply curious as to what the variable is that causes it on some files, but no others.
Maybe in the way the files was created, but what do I know

It was touch and go a few times Neil...

The thing I found was that the black night sky, messing with storm clouds:

or heavy overcast for instance all worked fine because I was able to "blend" each side of the ace file so that it matched the piece it was going to join. Similarly, working with an ace where you have mainly blue sky was fine, but as soon as I found an interesting shot with lots of clouds (like ak's example) - especially a variation in colour, I hit a wall. The uniform edge method so it joins properly looks terrible on an ace file where you have absolutely no uniformity amongst the cloud, colours, light etc. I'll leave that to the experts.
