Linear interpolation (mix, blend, interp) is one of those obvious functions you end up using everywhere. Do you know, however, why we can't simply blend between UV projections? 🙂 This and more explained in my in-depth video on Lerp www.patreon.com/techartaid/p... #UE5 #gamedev #gameart #techart

📚 I recommend: Cory Doctorow's "The Reverse Centaur's Guide to Life after AI". My short review: www.patreon.com/posts/169328... His stance isn't against the tech per se. It's about control and purpose. AI feels different when we *can* use it ourselves at will, vs when we're forced into it at work.

Huh! So it shows what the ceiling of engine business may be worth, right? Not much, with little space for growth... Then even if they add tremendous value, engine makers capped by customers' business limits too. And raise the costs a little too much, they will consider building own engine

Didn't get to participate in GGJ this year (or the past several years tbh) but, given the theme was "Bubble" I thought I'd reshare my anime bubble shader I made a while back, inspired by the amazing "Bubble" anime film I said "bubble" way too much in this post, it stopped sounding like a real word

Do you know the PBR "issue" when a shader blends between 2 materials, like concrete and water? The white banding on the transition? 🧐 Well, here's a concerning photo from Warsaw. Apparently Poland runs on cheaper quality settings. We do a classic lerp instead of clear-coat compositing 🫠

Also @codekitten.me I've been arguing in the studio for years that distance-based shader optimization isn't worth it imo :D Because... it's small. So it optimizes itself. And after few dozen meters you have proxies (HLOD) anyway. But maybe I'm wrong?

POM decals were one of tech art's fav inventions in the project! Thx for putting a spotlight on them☺️ Using it on just decals amortized the cost, making it viable on XB1/PS4 We made the number of steps dependent on the angle. What you see here is probably an artifact of that (or interpolation)

We're highly social creatures, we want to belong to a community, & want to care for each other. It's far more effective for us to feel that we've let someone down, than to be punished, but we need to have a sense of responsibility first. Then we get the rewards & security from that community

In my times™ we didn't even have shaders! Kids were going barefoot to the nearest village, hands frostbitten from a real winter, to bring a chunk of fresh T&L for supper. Combiners, maybe, if you were lucky. Despite, we were full of awe – and gratitude! hmph
