URP particle-based screen distortion. 🖥️ Particles are in the 3D world, but use screen coordinates to distort what's behind them. Excellent for shockwaves! ⭕️ A bit more work + polish, and I can throw the shader on GitHub. #unity3d #gamedev #realtimevfx

During the debug view, you'll see what's basically this.

Aaaand, I've gone too far.

Progress.

Remake and cleanup :)

Amazing! The distortion also affects transparent materials?

Mirza Beig3 years ago

There are very few transparent materials in the scene. I think maybe only two, and one of them is the distortion. The other one is behind it, as a soft glow for when the particles strike the cube. 💥

One of the features I find lacking in Unity's trail renderer is something like 'Noise over Lifetime' to add wispy, fluid-like motion along the length of the trail mesh. ✨ Shaders to the rescue: Below is a particle system emitting trails with my caustic noise fire shader. I'm masking the 3D vertex offsets by the UV axis. #unity3d #gamedev #realtimevfx

$🧑‍🏫 How to make a glass/refraction shader: 🍷 Refraction will ultimately have the effect that whatever is behind your mesh should appear distorted by the surface of the mesh itself. We're not going for external caustics projection, just modelling glass-like, distorting "transparency". 🌆 In Unity, you can sample the *global* _CameraOpaqueTexture (make sure it's enabled in your URP asset settings), which is what your scene looks like rendered without any transparent objects. In Shader Graph, you can simply use the Scene Colour node. 🔢 The UVs required for this texture are the normalized screen coordinates, so if we offset/warp/distort these coordinates and sample the texture, we ultimately produce a distorted image. We can offset the UVs by some normal map, as well as a refraction vector based on the direction from the camera -> the vertex/fragment (flip viewDir, which is otherwise vertex/fragment -> camera) and normals of the object. 📸 Input the (reversed) world space view direction and normal into HLSL refract. **Convert the refraction direction vector to tangent space before adding it to the screen UV.** Use the result to sample _CameraOpaqueTexture. refract(-worldViewDirection, worldNormal, eta); eta -> refraction ratio (from_IOR / to_IOR), > for air, 1.0 / indexOfRefraction (IOR). IOR of water = 1.33, glass = 1.54... 💡 You can also do naive "looks about right" hacks: fresnel -> normal from grayscale, which can be used for distortion. Or distort it any other way (without even specifically using refract at all), really... 🧠 Thus, even if your object is rendered as a transparent type (and vanilla Unity URP will require that it is), it is fully 'opaque' (max alpha), but it renders on its surface what is behind it, using the screen UV. If you distort those UVs by the camera view and normals of the surface it will be rendered on, it then appears like refractive glass on that surface. > Transparent render queue, but alpha = 1.0.$

And it works!!!!!!! 😍👌 Made a whole computer room from 1995 with Three.js on the web using Claude Code (on the server) in just a few hours I can connect to the internet and surf the web, play DOOM and mIRC and read the news, all in 3d now I like going super close to the screen and see the pixels I can't get blended occlusion to work yet though (so screen still shows as a perpetual overlay), maybe mrdoob knows how to fix And I have to figure out how to add that border-radius/distortion to the screen too But very nice progress for today 😊

Game juice isn't just about particles and postprocessing, Your UI should react to what happens on screen too! In this example, the UI gets various VFX effects reacting to what happens. There are also shader animations to make it feel alive. #Gamedev #indiedev #GodotEngine

I wanted to see if making N 3D would be fun! experimenting with an xray shader that hides walls based on whether their plane intersects the center of the screen in front of the player. was a headache but I think it should make exploring interiors more interesting #godot

Nobody asked for it… literally NOBODY But I still went ahead and brought back that glorious old-school Duke Nukem 3D / Build Engine screen distortion when you look up/down in #UE5 (can switched with just a click) #UnrealEngine #UnrealEngine5 #gamedev #retro #UE5RFX

Fully realtime 3D inflation shader in Figma. Pretty hyped about this one! Need to polish it up and make the UI a bit easier to use but will share in a couple of days. Soooo much fun to play with!

Thank you Figma for building the best 3D software ever! Jokes aside, this is probably the first and only 3D engine built in Figma. It uses mathematical transformations to project 3D coordinates on a 2D plane (your screen) Check it here:

I was interviewed by 80 LEVEL, where I had the opportunity to share my journey and insights over the past ~14 years in motion graphics, tech. art, medical communications, and game development. Lots of pictures and videos, especially from my work in #realtimevfx. Although the oldest two are from a text-based adventure and retro CGI of an ocean being vaporized. #gamedev #unity3d #aftereffects

What's y'alls thoughts on Starting Soon Screens? I see some folk go 5, 10, even 20mins on them, but I have yet to make/use one myself 😅 I just throw Clucks (TTS pet) in the middle of the screen for ~1-2mins & yap while I get situated. Then go straight into w/e we're gonna do

One last(?) tweak to the automap shader - switched to using the screen position vs world position for determining which parts of the map to fade out, so you can always see your player/focal point no matter the angle, which is a huge help on vertically stacked maps #gamedev

More C64 LittleBigPlanet 8-bit Coding! - Did some work on interactions with Physics Ball, can now go behind and in front of it (That was more pain than I thought it would be!), can stand on it and get a high bounce by holding jump button when you land on it and can also walk on the ball for some clown action! The ball also kind of rolls down 'slopes', (or rather falls off corners), and it also has a proper world position now so can actually be moved from screen to screen - should be able to make some gameplay with this...in theory! #LittleBigPlanet #Sackboy #C64 #8bitart #football

$I am having a lot of fun with this ThreeJS game. Will probably be spending more time on this cosy flyer game for #vibejam And btw, shaders are awesome! I highly recommend anyone building a 3D game to add some shaders to make your game look good. Here's a quick primer on the different types of shaders you can tell your AI to level up your game's graphics: - Noise-based shader for water refractions or shimmer - Fresnel shader for a nice rim lighting effect on your 3D game objects - Post-processing shader to change your game's color scheme dynamically - Post-processing shaders like the VHS effect that @levelsio use for the Drone flyer game - Shader effect to make the trees sway or objects wobble - and many more uses Shaders are incredibly versatile and useful. I would recommend you to go YT to check out some shader basics videos and come up with more creative uses for them!$

🤯 with OpenAI Whisper + TTS + GPT4V, you can just permanently share your screen with an AI and talk to it to get help on anything on screen. a generally intelligent assistant for your digital life. with a bit more engineering you could probably feed it extra docs and context based on the currently active tab/app.
