Bevy Bistro Example

Note bevy 0.18 has an issue using compressed textures: https://github.com/bevyengine/bevy/issues/21490

Download scene from https://developer.nvidia.com/orca/amazon-lumberyard-bistro (or see link below for processed glTF files with instancing)

Reexport BistroExterior.fbx and BistroInterior_Wine.fbx as GLTF files (in .gltf + .bin + textures format). Move the files into the respective bistro_exterior and bistro_interior_wine folders.

• Press 1, 2 or 3 for various camera positions.
• Press B for benchmark.
• Press to animate camera along path.

To optionally convert the textures to KTX2 use: cargo run -- --convert. You need kram in your path to do this. It will convert all the textures to BC7 KTX2 zstd 0 using available_parallelism() and update the gltf files to use the KTX2 textures. Or use compress feature with --compress arg to generate compressed textures with mipmaps at runtime. --cache will additionally cache the compressed textures. So to run with cached runtime compression: cargo run --release --features compress -- --compress --cache

Alternate processed files with instancing (glTF files on discord):

• Fixed most of the metallic from fbx issue by using a script that makes everything dielectric unless it has metal in the name of the material
• Made the plants alpha clip instead of blend
• Setup the glassware/liquid materials correctly
• Mesh origins are at individual bounding box center instead of world origin
• Removed duplicate vertices (There were lots of odd cases, often making one instance not match another that would otherwise exactly match)
• Made the scene use instances (unique mesh count 3880 -> 1188)
• Removed 2 cases where duplicated meshes were overlapping
• Setup some of the interior/exterior lights with actual sources
• Setup some basic fake GI
• Use included scene HDRI for IBL
