Looks awesome. Anything been made with this?

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.

Does this use BSPs for draw optimization?

xyzsparetimexyz 3mo ago ↗

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

vicioussquid 3mo ago ↗

Nope, all done real-time using Frustum culling.

`Baking` of lightmaps is supported but not currently necessary

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
