![]() I think it's still worth it if it saves you megabytes of mesh-data. The only downside of this is that the decoder itself needs some resources: decoding isn't free and the decoder itself is another 320kB of data to be loaded by the browser. tDRACOLoader(new DRACOLoader()) Īfter that, you can use the GLTFLoader as before. Finally, you need to tell your GLTFLoader that you know how to handle DRACO-compression: tDecoderPath('path/to/draco-decoder') Now you have to go through some extra-steps to load the file, as the regular GLTFLoader doesn't support DRACO-compressed meshes.Įssentially, you need to import the THREE.DRACOLoader and the draco-decoder. ![]() If vertex-data was the reason for the file being that big, the compressed file should be considerably smaller than the original.

In that case you can use the DRACO compression-library to get the size down even further.įirst, to test the compressor, you can run npx gltf-pipeline -i original.glb -d pressionLevel 10 -o compressed.glb To adjust any of the denoiser settings, you can add them to the Console Variables so they only apply during a render.There might be, if it is the vertex-data that is causing the file to be that big. You may also want to consider disabling the following Denoisers entirely if you have a high enough sample count (64+): Setting these variables to 0 will help the denoiser converge better without temporal history. Want to learn how to lower and optimize your Unreal Engine project file sizes During one of my Twitch streams we investigated this. When using high-resolution tiling or when disabling Temporal anti-aliasing, you may need to adjust the following console variables for better results: Link official doc Unreal Engine makes real-time ray tracing possible through the use of denoising techniques that may rely on temporal history. The Level Blueprint now has instructions to play the desired Level Sequence when the level begins playing so a the animation we created plays when we hit play game in the editor:įorce All Ray Tracing Effects How To Load Levels in Game Play Render Lighting Only Play Level Sequence with Key Stroke
