Hey, I'm curious, did you end up trying it out? :)

Thanks a lot for that. That's some really good input. I'll experiment with that, might follow up with a DM some point in the future if it's ok :)

I tried blending only the x-axis in the camera's local space, which eliminates the flipping problem, but as soon as I include the `dot(playerVel, camForward)` somewhere in the blend process it gets super disorienting.

Thanks! How do you blend the positions?
When I blend in world space I get issues with the player running straight into the camera and that in turn affecting the movement direction (i.e. causing flipping like in the video if unhandled).

Any tips for avoiding/reducing motion sickness with the lookahead functionality? I'm trying to figure out what's wrong with mine 😬

Oh how cool!! Thanks a lot and for writing the article in the first place :)
Big fan of your gameart breakdowns!

feel free to replicate, this is what I used to compress the hdr map: husong.me/ktx2-encoder...
this is what I used to measure VRAM (in WebGL) github.com/greggman/web...

~ 200k triangles

I'm not sure tbh, I'm new to these formats as well and just looking at the reported numbers, though it would be good to dig into it. My measurements might have been off by sth as well, not sure if I subtracted the framebuffer VRAM correctly. But they were > 100mb for sure. Maybe bc it's UASTC HDR?

I measured this with github.com/greggman/web..., so only an estimate, but the order of magnitude should be right.

But roughly checks out, doesn't it?
(2048 * 4096 * 25) / (1024 * 1024) = 200

inspiration came from this excellent breakdown of the technique by @simonschreibt.bsky.social

Yup, +1 for the audio book.
The craft sequence series by Max Gladstone is so good as well.
