PBR never gets old! New renderer has a nice way to generate custom mips, so I can actually get good IBL this time around. Also, bloom!

This sounds familiar! I occasionally get to the higher levels of making a game, and I inevitably get struck by the idea "This is hard! I can build a tool to make this easier!" ...and then I have a neat tool but no game 😅

So uh, always be wary of caching! And threading.

I had a lot of different theories I chased! But ultimately it was a that the sprite aspect ratio got pre-calculated right after the image was loaded, (loading happens on a separate thread) and it would occasionally race fast enough to cache an aspect of 0/0 before the width and height got filled out

I had a bug where, occasionally, a Sprite would be invisible! It was never the same Sprite, and it would only happen rarely. I actually never even was able to witness this bug myself, though QA had a screenshot or two of it!

Probably shortly after Apple adds OpenXR support! 😅
But for real, I don't think I'll have the bandwidth for also maintaining a visionOS backend. If someone ever makes an OpenXR shim for visionOS, that might make the idea much more tempting!
I'd like to support SK's simulator running on Mac though.

I've considered Quest+Link to be legacy for a long time now. It's sad to imagine what could have been, but I'm a fan of what Virtual Desktop has been doing!
Epic has MegaGrants, I've seen them be rather generous there in the past!
Unity historically holds features/platforms hostage for money.

Even within the Unity ecosystem, Vendor SDKs aren't required, and working around them will make your app actually portable! See @openbrush.app and @mikesky.dev's work as an excellent example here.

IMO, everyone should try counting calories for a bit, even without a particular goal! At the very least to build or calibrate intuition about how much certain foods cost. Food portions can be absolutely wild!

Next time I need to diet, I'll probably aim for less than 90 days, perhaps with a deficit larger than 350. I didn't feel _very_ hungry except towards the end, so I expect I may still have some additional tolerance. But I _do_ think I'd want to avoid spending much time with my metabolism down so far!

What surprised me was how much my metabolism dropped while dieting! If MacroFactor is to be trusted, I started at 2.2k calories a day and went to 2k at the end! This would trip me up a lot if I wasn't aware, and I suspect it was responsible for a large drop in my general energy in the evenings.
