This is nightmare. It has a lot of bugs. You add something with gaia, delete it from hierarchy and still you got plenty of warnings of non existing gameobjects. Controlling the loading terrain is horrible, fix origin floating points its not working. I was trying to get support on their official discord, but they generally answered to you with "strange, ignore it". This is not 5$ asset, its very expensive and for that money support need to be better. Going to report this asset to Unity support, because its not usable right now

Saves a lot of time. There are bugs, but considering the amount of tools and features its nothing that really slows my work down. After getting used to the issues with the asset you can easy work around the issues. Very powerful asset which saves weeks of development time

Of all the versions of GAIA this is the worst. cost a ton, less features, and more limitations, is buggy, etc. Even with a powerful PC just downloading and importing it will bring anything you wanted to do with your computer to a stop for about half an hour at best. When setting up terrain it could randomly freeze and try to have Unity compile something which will take another hour and even prevents you from closing Unity eve3n through Task Manager. And fun new bug I just found is after the crash the project wont open anymore

This asset costs 265€ and when you import it, it has bugs. For this amount of money spent, I'd expect the tool, when imported, to at least not have bugs. I am very disappointed and would not recommend it to anyone.

When it works, it is ok but it is a bit buggy with minor hickups here and there, and sometimes you just delete it cos it is so full of nonsense you don't wanna deal with it. The added bells and whistles are cool though with wind generation, ambient audio, etc.

It has many tool for providing quick and general areas for my game! It's not perfectly geared for millimetric placement but you cans till modify things by hand after generation.

There is not much to say, if you want to quickly create stunning terrains and populate them with ease, this is the asset for you. It is easy to use and can generate whatever terrain you like, fleshing out the world with the customizable spawners in seconds. I can't recommend this enough.

I got this asset in some sale bundle since I was interested in being able to generate populated terrains. At first, it is quite challenging and feels a bit over engineerd, however, there are nice video tutorials that set you in the right path. The highlight for me is the support though. I had two different issues and after posting them in the forum got daily replies with helpful insight that lead to a solution.

Let's start with the good things: the asset (when it works) does what is promised. It's a great way to crate a large terrain in a short time. If you use the pre-made biomes, it's just a matter of a few clicks. But the quality of those is not exceptional, so maybe you want to either replace textures and tweak lighting or maybe you want to create your own altogether. I tested with BI and URP, and with those pipelines, Gaia is great. HOWEVER.... When you start changing things (say, you remove the gaia runtime and re-create it) then things break easily and it's very difficult to find out why. I had to start many times over because of this. And here is the weird fact. With so many evaluations and reviews, I'd expect the Gaia community to be very active. Instead, the forums are deserted and the moderators answer your questions after a day or two, which means you're mostly on your own to figure bugs out. Lighting-wise, built-in and URP are fine, but HDRP time of day breaks REALISTIC lighting fully and I wasn't able to create an override volume capable of fixing it, with the result I need to buy/create my own weather controller. So, would I recommend Gaia? I don't know, it depends on your use case: 1) Do you need it for creating big worlds only? Yes 2) Do you are fine with the biome quality out of the box? 3) Do you use built-in or URP pipelines? Yes 4) Do you use HDRP and you want to use the Weather effects built in Gaia? NO 5) Don't you have time to dig into the frequent breaks? NO 6) Do you want to rely on a solid community for help/inspiration? NO This is my experience after 2 weeks of using gaia every day. I may change this evaluation in the future.

So far I have used this for terrain texturing and stamping. Yet to completely explore it but excited!!. Also its pretty stable and works pretty well. No crashes or bugs so far.
