Ugh this makes me nostalgic for the days of Q3-era game map making and custom servers. I used to get lost in the various games Radiant variants as a teen building DM and CTF maps for my clans server.

Did you end up going into game dev or just generally software development? I'm always jealous of the people who grew up making maps or game mods, I wish I'd been more motivated when I was younger to do stuff like that.

Software dev. Game dev never really appealed to me. I kind of have an artsy streak inside of me and map making always felt like additive sculpture which is probably why it appealed.

Good luck to you. Having worked in this space for around 10 years I can say it's nearly impossible to arouse anyone's interest since the market is so totally saturated.

For a new engine to take on it needs do something else nobody else is doing so that it's got that elusive USP.

Getting visibility, SEO hacking etc is more important than the product itself.

My USP is specifically targeting Snapdragon 8CX (a mobile CPU) and OpenGL 3.3 with Adreno graphics

Does this use BSPs for draw optimization?

Nobody uses BSPs for draw optimization. We have culling and depth buffer techniques for that now

This doesn’t make sense. BSP is a form of culling.

Nope, all done real-time using Frustum culling.

`Baking` of lightmaps is supported but not currently necessary

Other than the 14 examples included, not yet; this is brand new and I am reaching out to the community to create some stuff with it, extend it with angled brushes, new entity types, etc

Thanks so much for your interest.

Now that I have built this tool I'm going to use it to create a game
