We have tried everything to get in touch with the developers. Via their official forum thread, and via email. We've given them plenty of time, but it's been radio silence for months. Do not buy this product. Instead you should look at the "Nested Prefabs" asset by Visual Design Cafe. I have been emailing with them and they have confirmed they are adding a full-fledged prefab parent/child feature around Jan/Feb 2018.

Apply prefab in Unity 2017 always stucks project.

There's a bunch of red flags about this product with people saying it's been mostly abandoned. Was willing to give it a shot anyways since it's being updated again but I couldn't even do that- importing the asset itself just crashes Unity in 5.6.1f1 (even in an empty project) so I can't even try it out.

This plugin is a besy buy on Asset Store. Forgot about normal prefabs, forgot about model reimporting issues. Its just work as expected. Also very respositive support and included full source, no dlls and other muddy stuff. Yes in some cases its can be slow a bit, but dont forget about a time that this tool can save for you. Our team save a ton of time when use this beautiful tool. And we will use its our future project thanks you buddy! You re best!

The Prefab Evolution is worst plugin. - breaks prefab's structure after applying - makes duplicates of objects - crashs Unity - doesn't work at all on large prefab dependencies (between each other prefabs) - author of the plugin is gone and don't support it at all

I use 5.3.6f1, when I do some model modify such as animation or rig, it will crash the unity editor.

When our project become larger, it slow down everything. I think it could be better to limit the nest prefab into specify folder, and I can control the necessary asset located into that folder, without interrupt other assets does not need nest prefab.

We use it massive in our big project. But its horrible. -very long lags to make changes -changed tons of files without user input -tons of nullP if open project or build in btach build -no support

As soon as your project is too big, Unity will slow down, slow down, slow down, until you just can't work. So, use this asset very very carefully. Also, each object tagged as evolved prefab will scream "missing component" the day you decide to uninstall Prefab Evolution. Think about fixing +1000 missing scripts, then decide if you want to make the jump.

The Plugin has too many bugs, and I send email to the publisher with no respond. I want Refund ！！！
