    Asset packs, tutorials, references — say where it came from.

  2. Bring the detail

    Versions, error text, what you already tried. "It does not work" is not a question anyone can answer.

AI upscaling will not save your frame budget (if you are CPU bound)

No, so, every second performance discussion now ends with "just turn on DLSS". Players say it, okay. Producers say it, less okay. Last month a producer said it in a meeting about our game thread at 21 ms. I almost had a stroke. What upscaling actually does Temporal upscalers (DLSS Super Resolution, FSR, XeSS, Unreal's own TSR) render the frame at a lower internal resolution and reconstruct a higher resolution image…

    A sensible post. The phrase 'very expensive placebo' applies to most of the graphics industry since 2018. Regards.

shader graph outline for sprites, how do you stop the edges getting cut off?

trying to do a simple 1px outline on sprites when you hover them, to show you can interact. shader graph in URP 2D. my approach: sample the main texture alpha 4 times with the UV offset by one texel up, down, left and right, add them up, subtract the original alpha, use that as the outline mask it works... except the outline is cut off at the edges of the sprite. like the top of the characters head has no outline at…

    solved, posting for future me: 1. sprite import settings, Mesh Type: Full Rect instead of Tight. tight hugs the visible pixels so there are no fragments outside the art to draw the outline on 2. the sprite needs at least 1px of transparent padding in the texture. mine were cropped exactly to the art 3. if you use a sprite atlas, set padding to 2 or more or the neighbour sprite bleeds into your outline thanks tunde, rubber duck of the day

How do you stop designers from putting logic on Tick in every Blueprint?

No, so. New project, Unreal 5, small team (6 programmers, 9 designers). Designers are great, they build fast. Problem: every Blueprint they make has Event Tick with something on it. Checking distance to player. Rotating a coin. Updating UI text every frame. We have 400+ actors in the level, game thread is 19 ms on target, and I measured 6 ms of it is Blueprint Tick. I tried: Talking about it in the meeting. Worked…

    same in Godot for my solo game, but I am the designer and the programmer so I can only shout at myself (´・ω・`) jake's manager-for-common-behaviours idea is good, I will steal it
  • Ondřej Hrubý
    in Bevy this is a system with a query filter, designer cannot accidentally make every entity tick 🦀
