How I stopped making games to create Unreal Engine plugins

Back in 2018, I was working on a Tekken clone with one of my friends.

To speed up the process, we imported A LOT of asset packs from the marketplace for 3d models, animations, and sounds. Slowly our project started to get bigger and bigger.

As you can imagine, this resulted in huge final builds.

Therefore I started googling: "How to delete unused assets in Unreal Engine".

And found Migrate your levels to a new project.

I refused to believe that was the only solution and started looking into alternatives.

I wrote a small piece of code mirroring the Migrating process.

I ran it into our project and deleted everything...

I failed a lot, but eventually, I was getting closer and closer.

Finally, I successfully cleaned up our project.

However, the pitch was rejected and we got no funding and we gave up on the project. But I decided to upload my code to the Unreal Marketplace.

The feedback from the community

In May 2019, it went live and since then I was expecting angry emails from people complaining about how their projects were destroyed.

Quiet the opposite happened, Clean Project stands today with an almost perfect 4.92/5 rating.

In the first year, it got 250+ downloads and some incredible reviews both here on the Marketplace and on our discord channel.

I still highly encourage people to have a backup of their project before running it.

But, it's safe to say this plugin has worked wonders for many projects with various sizes and teams.

The guarantees

#1 Premium quality support: There is a high chance you won't need it, but if you have any troubles or suggestions, professional and lightning-speed support forever is included.

#2 Updates for future engine version: I've been working on plugins since 4.20 and I plan to upgrade them forever. Today I have automated pipelines to test and deliver updates directly.

#3 No upgrades or subscriptions: This is the only version of the plugin, there will be no Pro or 2.0 plugin. All future upgrades will be done to this product.
