    Would like to see way better-looking clouds. It looks like my Lightwave 3d from the 90s. Hope you improve that.

    Great addon, just needs to improve the clouds a little bit more.

    A time saving physics-based addon that lets you create realistic atmospheres and suns in the world shader with just a few clicks! highly recommending this for every artist but for future updates, I would really like a moon feature added as well. ofc you can use the PCO addon to do that, but a more realistic earth's moon would be a great addition to the addon.

    This potentially has lot's of promise, but is completely unstable and unreliable in any sort of production setting because of the amount of bugs it has. Just simply turning off PSA and then turning it on again results in not being able to adjust any settings, and essentially destroys all your shaders in almost every material you have. It adds additional nodes to a lot of materials you have (not even in the world nodes).

    Good to maybe experiment with small projects but I would not use in any real projects where you have deliverables until these bugs are gone. When you're paying a relatively high price for something like this, you'd think that it would be more stable. I have version 1.5.2 btw.

      Hey Nathaniel,
      Thank you for the feedback! Regarding stability, we **highly suggest** updating to the latest PSA version v1.6.1 (release notes here: []( as it should tackle all issues you are facing now (issues with missing data-block nodes that were caused when disabling addon, sun position animation stutters, issues when trying to animate some of the properties and more). Also, you will gain a lot of new features that are not present in v1.5.1 (more controls over stars and clouds). Sorry for any inconvenience caused by these issues and we hope that you will enjoy the new features and a more stable addon.

    Always wanted a more controlled approach for my world than what HDRIs offer and this was the answer all along! I have used this for many projects and it has never let me down :>

    I had rough times with this add, I see the potential, but I find it quite hard to to play with it, maybe I need more time.
    Overall it wont match the quality of a real hdri, the clouds are very poor even though it s cool to have them, they dont look real at all.
    I also find the presets very poor, and not very helpful.
    I also had trouble when I was switching to hdri, psa leaves things even tho you erase it.
    I will it more time and chance, and update my comment, but for now i am disappointed.

    It worked well until the last versions. Sometimes it simply doesn´t work. I wish to know why, but after spending hours triyin even to know under which circunstances it happen, I can only say this: At some point the add doesn´t repond to the changes you made in the interface. And there is also a problem with the Alpha tree add on. I can say that once I add an alpha tree element, PSA stop responding. This is the most recent problem but before this there was another problem with alpha trees: The PSA fog material doesn´t work properly, because the fog can be seen in the transparent areas of the alpha tree planes, which is not good and create a weird effect. (alpha tree uses images with alha channel to recreate trees)

    The add-on looks nice but it causes a lot of bugs with world setting, when it's not the world going black after chaging or re-activating the add-on or replacing it with an HDRI, it's the settings not reacting to changes or the clouds not showing up...

    Also for an add-on this pricey the updates come very slow and never fixed the issues mentioned above, you don't get a moon light setting and/or texture to render night scenes either.

    I would recommend this add-on if you find it on sale, but for the full price I think it has too many issues and less features than it should.

      Thank you for your feedback, David!
      Due to multiple circumstances fixing the material fog issue (that causes broken/black materials) got delayed, but we are working to release it this week. Regarding settings that are not updating and clouds that are not showing up - could you please send steps to reproduce these issues on our Discord #help section ( and I will get back to you ASAP. About star textures - feel free to ping us on Discord and we'll point you to the NASA official textures.
