I removed the 7 year review to write this new one here, because I just tested Mantis with Unity 6.3 LTS and it works super fine!

Original Post: Need the author to rebuild the libMantisLOD.so to support 16 KB page size. Otherwise, the Google Store won't accept the APK. I'll update the review when it has been fixed. 2025-Dec-17: We have fixed this issue; it turns out it's not the asset's issue, it's the Unity compiles this asset into .so file for the Android platform. We simply upgrade the Unity version from 2022.3.62f3 to Unity 6000.0.64f1, and the libMantisLOD.so is 16KB page size aligned.

base/lib/arm64-v8a/libMantisLOD.so - Does not support 16 KB Memory page size Google does warn that this lib MUST be updated to support 16KB Memory page size. Please update this lib!

This is by far and away the best tool for taking those ridiculous models you buy on stores and turning them into something game-ready. I can generate LODs in just a few clicks, saving time and money. You won't regret buying this.

One of those fundamentally awesome assets that Unity should have bought when they we're off teh rails making purchases. Would have been a much better investment for the company and its users. If you use any assets like Synty you can usually drop your tri count by 1/4 to 1/3rd and barley notice anything. Or keep your models the same and add LODs so you can fit way more into your scenes.

VRchatのPerformance Rankではpolygon数の制限があり70,000ポリゴンを越えると「VeryPoor」と判定されます（2024年3月21日現在） Mantis LOD Editorを利用する事で、既存のアバターのpolygon数を外観の変化を最小に抑えつつ、効率よく削減する事が可能です。 polygon数削減対策の方法はいくつかありますが、MantisLODEditorは効果的な選択肢の1つであると言えます。 In VRChat's Performance Rank, there is a polygon count limit. Exceeding 70,000 polygons results in a "Very Poor" rating. Using Mantis LOD Editor, it is possible to efficiently reduce the polygon count of an existing avatar while minimizing changes to its appearance. There are several methods for reducing polygon counts, but Mantis LOD Editor is considered one of the effective options.

Really nice optimizer. Amazing, really easy to use. I got a little too comfy using it and it sort of messed up my model because I saved it on 25 % quality and it looked horrible. I couldn't undo it but fortunately I had a back and I re imported the model and everything fine.

Worth every penny. cant imagine working in unity with out it. works out of the box.

This asset is amazing. You are greater than Newton and the savior of my life, haha. If you create more assets related to optimization, I will buy them even if it means spending all my fortune.
