@mjp123.bsky.social you’re gonna have to carry the Britney Spears torch

Sure. It's not specific to foliage. You'll be able to enable it on anything. Probably won't work great for everything though.

The Witcher 4 logo is printed in the bottom left corner alongside text that reads, “Technical Presentation — Not Actual Gameplay.”

Really enjoyed this talk. Thank you!

Wow. This image brought back memories. Wrote my very first exporter for Milkshape in university. It could only handle a single material 😆

where are all my programming language developers at

“Lord Validation, the fleet has reviewed our bindings and have determined tha… unggggggg”

And if I’m being honest, especially with DX going Spir-v as an IR, just choosing one language is great but syntactically I like where HLSL 2021 is headed more than Slang in some very specific ways

The prospect of Slang being the new multi-platform standard shading language is very interesting to me, especially in terms of bridging the gap between Vulkan and DX, but I’d really love to see these both come together syntactically wrt templates and struct member func behavior

ISP see what you did there

New site, new you. Time to upgrade to an AVX pun?

Sometimes retroactively. I’ve gotten validation errors on code that’s been checked in for months. It’s not fair if they keep moving the goal posts!
