Finished Expedition 33 and all the side content! I had tremendous amounts of fun throughout the 60 odd hours it took me to finish it (I did have to cheese Simon, I'm not built like that). Congrats to the development team, and thanks for all the chroma 👨🎨

Kamppi Chapel in Helsinki, looking very dark at grazing angles.
Something's wrong with the Fresnel term on the BRDF, may have forgotten to invert the cosine term 🤔

I've been meaning to do some write-ups that are hopefully useful, so this first one is about my approach to Order-Independent Transparency.

🙌Super excited to finally release this!🙌
I hope you enjoy it!
Super Mario 64 (1996, Nintendo 64) uses blob shadows for characters. Left: A blob shadow overlapping with tree shadows. Center: A blob shadow getting clipped using a hardware decal feature. Right: All moving characters and objects have their own shadow. The clipped shadow inside that transparent bubble shows the limitation of the Nintendo 64 decal feature. Screenshots taken in the ares emulator.
Left: Crash Bandicoot: Warped (1998, PlayStation) renders shadow textures at runtime. Right: Soldier of Fortune (2000, PC) also does but at a lower resolution.
I wrote about video game shadow techniques on my blog:

I've always liked different ways to draw shadows in games. I went and tried to find visually distinct examples and explain their differences. I hope you'll find it inspiring!
I feel like in the past few years I've unlearned how to tweet. The website kept getting worse and worse. I used to really enjoy sharing my thoughts, shiny pixels and random pictures. So far I'm enjoying Bluesky, so I'm going to force myself to be a bit more active for a while and see if it sticks :)
