While we were able to upload decals at any resolution we wanted, I managed to make a few skyboxes (each at 900x900 pixels).
The links to them are here:
If you look at them in game or studio, they are very clear. I could of uploaded two more but my computer crashed after they were finished. So far I haven’t experienced any performance issues from them being so big of resolution.
Thank you very much for posting these. 
They look great!
These look amazing, thanks for sharing.
Amazing! But anyway I can rotate the early morining one clockwise 90 degrees? It would look awesome becuase the sunset would be framed by a canyon.
Wow love the Peaceful Morning Sky! Looks amazing.
Yea, I am not sure how you would rotate a skybox. You should if not. The morning skybox; I was wanting to make it line up with Roblox’s celestial bodies. Like at 6:30:00 AM it is perfectly in front of the sun in the skybox. I managed to make it (after some trail and error) but Roblox put the resolution limit back on before I got the chance to upload the right decals. I could still upload it but it won’t be high resolution and clear.

High-res decals uploads are re-enabled, btw.
I’m not sure if they are this very second, but they certainly were yesterday.

Legit? I’ll go try it out.
HD uploads are in fact enabled; I’m not sure how high it goes, but I was able to upload 1024x1024 images for a skybox and it seems fine.

I tested it the other day, the limit is indeed 1024x1024.
Since we’re on the subject, I’d like to populate this Set with more skyboxes. I’ve already found a few.

I’d like to have it only contain quality skyboxes, so I’ve invented some criteria:
These were great until I noticed the BMP extensions. I’ll add these if you reupload them as PNG (and the file sizes are small enough).
This one is a really good example in my opinion. The images are high-res, but the file sizes are super tiny.
I made a few more, they might not be moderated yet. It’s hard to find good royalty free assets

Mine are around 2.6 MB per panel and I may do .png. And is there something I should worry about uploading as BMP?
[quote] Mine are around 2.6 MB per panel and I may do .png. And is there something I should worry about uploading as BMP? [/quote]PNG is a superior format. PNG gives you very decent, lossless compression (no artifacts, unlike lossy JPEG).
PNG is also widely supported and allows transparency. PNG is just awesome.
I’d elaborate more, but I’m typing off of my phone. 
Okay, I’m taking the advice of .png instead of .bmp and re-uploaded them. I also updated the morning skybox so it matches with the sun at 06:25:00.

I’m not really sure of a good number for the file size. 2 or 3MB is definitely pushing it. [/quote]
To that end I’ve started putting the approximate total size of all 6 images in the description of skyboxes I upload. Might put a link to your set in there too to spread it around.
Also 3 more skyboxes up - another from TF2 and 2 official skyboxes that I found a couple of years ago that seemingly never saw the light of day.
Not everyone has a million megabits of bandwidth. Ideally, the entire skybox should download in a few seconds for most users.

Looks like you messed up the links. Make sure they look like this:
http://www.roblox.com/asset/?id=<asset-id-here>In your case, you used “assets” instead of “asset”.
Also, I’ve updated the criteria to indicate a maximum resolution of 1024x1024.

Yeah, I’ve done some research and it’s conclusive that .bmp format loads slower than .png (depending on the internet speed.) The skybox panels are around 400-600KB now that they’re formatted to .png.

Fixed (I was tired)
Still too large, I think. I ran your images of Light Blue Skybox2 through OptiPNG without even messing with any parameters, and it managed to reduce the total size from 4.4MB to 2.8MB. To anyone uploading PNGs, I suggest using this first.
