Virtual Textures in the Browser. This is a WebGL 2.0 implementation I did in 2023. The car model is from Sketchfab by Pavel Matoušek. It's a worst-case for virtual textures because the texture is generated from photogrametry software and has pathologically bad UV layout. The texture is 16,384 x...

"Assassin’s Creed: Odyssey" map of Greece on a single 32,768 x 32,768 texture in the Browser. Virtual Texture tech in WebGL 2.0 The source is a 804 Mb PNG. Without Virtual Texture tech you'd need to download that and wait for a few seconds for your browser to decode it before you could use it. Your browser would then crash when it tries to upload it to the GPU :) If we imagine that the upload to the GPU would succeed - it would take 4Gb of VRAM. Virtual Texture loads immediately, because the image is split into small fixed-sized tiles with full LoD chain (mips) and uses 2048x2048, which is just 16 Mb of VRAM. Article:

I’m trying to re-texture my avatar in #EmoteLab it’s very cute! > Texture Cache > CoffeeBean > Custom Textures - Go back to EmoteLab and click Reload Textures. Method 2: Easier Way to Edit Textures Directly - Go to Settings → Open Character Folder. - Find the version you are using, then open your character folder. - Click Regions. - You will find the textures used by the character there. You can edit these textures directly as well. 💡Tip: I recommend editing the WeightTransfer folder first, then Click Unload Current Model and Load the model again to refresh the textures. Finally, You will get your own EmoteLab texture!!

Testing a method to blend objects into the terrain surface. This allows the terrain virtual texture and height to be sampled at pixels' world position and blended in to the object's texture. The terrain normal is computed from the height and also blended with the object normal.

#VRChat guide on how to reduce download size and texture memory by optimizing textures. Super easy to do by literally anyone, with minimal effort. The jist is, REDUCE TEXTURE SIZES! most of your textures are probably wayyyy larger than is needed. Part 1/2

Here's another little showcase of the pitches. The problematic thing is that the pitches for the lower settings use a very different texture style, which is a bit of a thorn in my side. Aside from that, the lighting is way overtuned. I'll post a screenshot in the next post.

Finally implemented texture blending on the terrain. The tile textures still need some work but it looks much better up close and gives me a lot more options than the giant single texture I was using for so long

Unity includes a tool for baking SDF textures: 🧊 I made this experimental shader for fully volumetric glass shaped to any object using a 3D distance texture. Handles layered self-refraction in a single pass (look at the ears, when the model is rotated), + explicit backface rendering via another camera -> texture pass. I don't have clear plans to add this to PRISM, but it's something I wanted to try out as a morning experiment (R&D, rendering/optics, performance -- for later).

Keep showing the process. So, the add-on is Ucupaint. Free add-on which makes texture painting in Blender much more interesting and maybe easier. #blender

Working on sparse volumetric light maps for WebGPU. Got generation part sorted. The resolution is adaptive, refining near geometry and skipping through most of the empty space. The video is question uses a map that's only 10MB in size, including everything. That's less the amount of GPU memory that a single leaf takes up on one of threes in the scene, or texture on one of the sign-posts. We get about 1 sample every 30 centimeters in the world space. As a side note: gave my renderer quite the workout, rendering each probe as a separate non-instanced mesh for debugging.

Jesus Christ, jnmartin has officially implemented his first big improvement over the N64 original for the Sega Dreamcast port of Mario Kart 64! Now the jumpotron monitor screens in Wario Stadium and and Luigi Raceway are updating at a full 30FPS, or 6x the framerate of the N64! ...and he's doing this entirely in software with the DC's SH4 CPU performing slow, direct VRAM reads from the framebuffer into a temporary buffer in system RAM which is later passed to OpenGL which transfers it back into VRAM to update the jumpotron texture with... and the freaking Dreamcast doesn't drop a frame doing all this shit! Might want to keep that in mind, as a community... That accessing texture memory or the framebuffer directly from the SH4 via the "uint16_t vram_s[]" symbol that the video API within KallistiOS exposes, while comparatively slow, is not actually so slow as to be unrealistic for a well-optimized game to do anything useful with... very interesting!

#UEFN Material tips 🗣️🔥 Use Bump Offset to create fake depth for textures. In this example, I used it to add a darker secondary fence texture that feels behind the main one, like in the 3D world, while remaining a 2D texture applied to the mesh.

Is it just me or does look the FINAL FANTASY VII rebirth demo really bad. Texture Quality is very bad , pop ins all the time and a lot of shimmering on very fine details. Apparently this game was built for the PS5 and it's not just a "remake". Is this correct?

Here's a progress update on my recreation of the Simpsons landscape material! I created a post process material that outlines edges of surfaces, I drew a cliff texture for slopes as well as a bush texture and its masks so I have full control over its outline and shadowing, and I improved the variation of colors and patterns on the ground. I'm so proud on how this is turning out so far! #UEFN #Fortnite

Great question! 🤔 How do you simulate *multiple* layers of glass/refraction in video games? In the last breakdown, I discussed how to create a glass shader in Unity URP. In essence, we were taking the render of the scene from the camera without any transparent objects. This is available in URP as the global _CameraOpaqueTexture. This is good enough for most use-cases, and more or less the classic way of doing it. 🔍 What is _CameraOpaqueTexture? As the name implies, there are no transparent objects rendered into this texture, so it's not possible by default to have something like a transparent-type ocean material/shader rendered through a refractive glass shader (which samples and distorts this texture to render on its surface, as if it's transparent). ⚠️ Why it’s tricky: It's much easier to sort without much further setup if you don't have refraction, and only a transparent material, because in that case you're not simulating the transparency yourself via sampling the rendered scene texture. But for refraction, it's required-- unless you want to go down the ray/path tracing route. You could simulate accurate, real dispersion... and that's about as expensive as it sounds, and it requires a rework of your entire rendering. --> 🚫 It's not a viable suggestion to offer. 📚 There are well-known terms regarding transparency sorting you can search up, but as you've specifically asked for refractive boxes, I'll discuss briefly about that. 🧱 Simulating layers of refraction: For this kind of rendering, you need some way to render the backfaces before rendering the front. And the backfaces that are rendered may contain whatever data you'd like for additional processing in the layer front-facing mesh render. 🧪 Examples: You could render the back face as a glass shader of its own, as an intermediate step after _CameraOpaqueTexture. Then you sample this texture instead and you end up with multi-layered refraction, "just like that". You can also render the back normals only, via a fully opaque shader, and use that to manually account for that during the front render. You could even bake in data needed for thickness in realtime. 🛠️ Without making it complicated for yourself, the most straightforward method is via render textures, and you can easily set some fractional resolution. Cameras in Unity have an open slot for target textures to render to. You can use custom render textures to process _SelfTexture2D. ⏱️ It's great to do low-resolution processing for more complex tasks, like blurring and caustics. You can get massive performance boosts, considering the square law and number of pixels/fragments that need calculations (quadratic scaling). 🚧 I've not fully exploited the possibilities myself, but research/development with PRISM is ongoing!
