Game engine developer from Australia, I’m keen to share what I’ve learned about optimising games. youtube.com/vercidiumhttps://bsky.app/profile/vercidium.comhttps://bsky.app/profile/vercidium.com/post/3loq7ligjk22zI was lucky enough to help playtest Rift Riff and I loved it. It releases tomorrow, I’m keen for my third playthrough!

Before the world was going completely dark at the same time the sun set, when in reality that doesn't happen until after sunset. #gamedev14 Jan 2025 10:28 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lfp24nqjwc2hhttps://bsky.app/profile/vercidium.com/post/3lf33nfly7s24I fixed grass shadows recently and the difference is night and day.

If a colour is 300 or brighter, it is extracted into a separate buffer, then downsampled 8 times and upsampled 8 times When applied to the scene at 10% strength, metal surfaces are nice and shiny:07 Dec 2024 12:12 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lcpoaa7qgk2ghttps://bsky.app/profile/vercidium.com/post/3lcmwetw34k26After spending 7 years learning OpenGL, I finally have stable shadows. No more flickering! Shadows and clip/light/view space have always confused me. And they still do. #gamedev06 Dec 2024 10:00 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lcmwetw34k26https://bsky.app/profile/vercidium.com/post/3lce5qdszzk2xBlock select is so useful. Use Shift + Alt to select multiple lines, then Home, End and Ctrl + Arrow Keys to navigate left and right. This refactor would take so long without it! #gamedev02 Dec 2024 22:18 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lce5qdszzk2xhttps://bsky.app/profile/vercidium.com/post/3lccxbuibcc27Hundreds of errors in Visual Studio, we meet again! After refactoring shaders to support hot reloading (which is awesome) I realised the way textures were bound to shaders wasn't great. So now, I'm refactoring shaders... again...02 Dec 2024 10:50 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lccxbuibcc27https://bsky.app/profile/vercidium.com/post/3lca6kmxqhs2tShader Hot Reloading is working! If the current shader string is different to the last, the shader gets recreated and its uniforms are reconnected. Also if the shader string is invalid (e.g. syntax error), it will revert to the last working shader. #gamedev01 Dec 2024 08:22 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lca6kmxqhs2thttps://bsky.app/profile/vercidium.com/post/3lc62aqdzns2fThe shader refactor is complete and the project is building again. Now it's time to fix all the runtime bugs 😅 The codebase is much leaner though: 157 files changed 4860 insertions 8485 deletions Net: 3625 lines deleted #gamedev30 Nov 2024 11:59 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lc62aqdzns2fhttps://bsky.app/profile/vercidium.com/post/3lc2u6fr5t22tWorking on a huge shader refactor today, with the goal of being able to hot reload shaders. Each shader used to be two large strings (one for the fragment shader and one for the vertex shader), but now they are constructed from these 5 strings. This keeps uniform and varying names consistent too!29 Nov 2024 05:33 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lc2u6fr5t22thttps://bsky.app/profile/vercidium.com/post/3lbz46xkjos2fWhy can you hear sounds above + below you in games, when your headphones only have speakers on the left + right?28 Nov 2024 12:51 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lbz46xkjos2fhttps://bsky.app/profile/vercidium.com/post/3lbwlqgrpwc2kFor every polished animation, there are countless attempts that didn't work 😅 #gamedev27 Nov 2024 12:51 +0000at://did:plc:bwgdw24xskc44thpvc77aw7f/app.bsky.feed.post/3lbwlqgrpwc2khttps://bsky.app/profile/vercidium.com/post/3lbvt7uzptk25What do you think of these "Dissolving Triangle" animations?
