    Great addon

    I have been working on a project for some time and from the very beginning I have had a problem with proper stage lighting and color reproduction. I bought a PSA in 3 minutes, ultimately just to test the possibilities, I set the sliders at my discretion and suddenly it turned out that I solved the problem in 150% because the final render looks much more realistic, which I did not expect. A simple thing, I recommend it very much, because it gives great results, does not burden so much, and the time saved is priceless.

    I agree with Hanterdro. This addon is fantastic! The clouds system just needs to be flexed out some more.

    I had seen the previews, trailers and examples of how cool PSA was, so when I chose to purchase it I got very disappointed when PSA seemingly caused issues with Blender, didn´t preview in Cycles and had all sorts of issues.
    I was ready to leave a 1-star review and move on to a better solution, but decided to reach out to the PSA support on Discord. I honestly expected to wait a few days to get a response, but I must admit that all of my preconceived notions were brought to shame.
    Not only did they respond almost instantly, but I also found out that most of the issues stemmed from an unrelated, corrupt Blender file and some mysterious issues with the Blender prefs. Now, PSA works as I hoped and while I still have a lot of experimenting to do to get the results I am going for, there is no doubt that this addon is a game-changer in terms of ease-of-use, flexibility and options.

    This is in my opinion the best sky addon so far.
    But why only 4 stars?

    - The clouds looks pretty underwelming (I would recommend using VDBs clouds)
    - The development of this addon feels super slow (in comparsion to other Blender addons)

    However, I still highly recommend this addon. Works for me better than any other sky addon which is currently availibe.

    I chose this Addon instead of Pure-Sky Pro. I'm not sure yet if I made the right choice? The sky presets that ship with this Addon are now in a Blend File that can be used in Blender's Asset Browser. However, when I open the Preset Blend File the the thumbnail images of the preset skies look great, but in some cases the render view in Blender looks nothing like the thumbnail image that represents it (e.g. tatooine, retrowave) and I can't see much change between any of these presets really? So, I'm not sure if there's something wrong with the shipped presets and think this needs looking into, and when corrected, maybe a few more could be included to get people started with this Addon?

    The clouds are a great idea in this product but they are not volumetric and could do with a bit more work to improve thier quality and usability. I think that as they currently are they can be useful for background distant views, but I suppose you could have a go at making your own volumetric clouds to use to supplement / replace the ones generated in this Addon - see the link here: (

    I also think an option to add a moons and a range of planet types into the scene would be a great addition to this Addon. And if this along with the other points / issues I've raised were dealt with, I think this Addon would possibly be the number one Addon in this space?

      Hi Neil,
      Thank you for your feedback! Indeed there's an issue where when applying the World asset it doesn't refresh the azimuth/elevation values and the generated atmosphere may look completely different than the one in the image, although it is a screenshot of the asset. There will be a hot-fix this week regarding this issue.

      In this addon, we have implemented a simple, but quite sophisticated (fast as they are procedurally generated and good for most cases) version of clouds. There is a future plan to develop advanced clouds as a separate addon as it is quite extensive work that has to be done in order to provide realistic and physically accurate clouds that perform well.

      Regarding planets - in the upcoming month we are about to release a new addon called Physical Celestial Objects (PCO) which would let you create physically accurate planets on a real scale with just a few clicks. You can see the progress of this addon in our Discord channel ( #showcase section.

      Thank you again for taking your time and writing the review <3!

    Fantastic realism and speed of use. Great add-on!

    However I'm currently having an issue - I have animated the world azimuth and elevation from morning to night and the world lighting is not updating on render or timeline scrolling.

    I then tried animating the sun object to see if this would help but the problem persists.

    Add-on is amazing but any help would be appreciated, thanks!

    Great potential however after I closed blender and reopened it (didn't make any changes) I can no longer render. It crashes. I am on blender 3.1.2 and addon version 1.5.1, also tried 1.3.X

    Product DOES have a lot of bugs, usually with a new version of blender, but what you get carried immense value. You're virtually crafting your own hdri, and now the clouds feature works well with 3.1 (maybe even 3.2). My current gripe is the loss of all preset options. They simply vanished. Is thisa known bug? Is there a fix on our end that can solve?

      Hi, thank you for your feedback!
      Regarding presets, since PSA addon version v1.5 we have moved from our custom preset solution to Asset Browser. About how to import assets and use them read more on our documentation page here: We are currently working to make using presets more user-friendly.

    Do you know that feeling that you get when you're walking outside in your hometown and the sky looks particularly breathtaking? The Sun is going down and you feel relaxed and exhilarated at the same time. You think to yourself: "I wish I could recreate what this incredible sky is making me feel right now." It's almost like that. Not quite, but almost.

    It's a lot of fun to play with, and I know that it's expensive, but it is definitely better than... well it's better than a lot of things that I have spent money on.
