Objective

Improve lighting; especially reflections.
Closes Image Based Lighting and HDRI Support #4581.

Solution

Implement environment maps, providing better ambient light.
Add microfacet multibounce approximation for specular highlights from Filament.
Occlusion is no longer incorrectly applied to direct lighting. It now only applies to diffuse indirect light. Unsure if it's also supposed to apply to specular indirect light - the glTF specification just says "indirect light". In the case of ambient occlusion, for instance, that's usually only calculated as diffuse though. For now, I'm choosing to apply this just to indirect diffuse light, and not specular.
Modified the PBR example to use an environment map, and have labels.
Added FallbackImageCubemap.

Implementation

IBL technique references can be found in environment_map.wgsl.
It's more accurate to use a LUT for the scale/bias. Filament has a good reference on generating this LUT. For now, I just used an analytic approximation.
For now, environment maps must first be prefiltered outside of bevy using a 3rd party tool. See the EnvironmentMap documentation.
Eventually, we should have our own prefiltering code, so that we can have dynamically changing environment maps, as well as let users drop in an HDR image and use asset preprocessing to create the needed textures using only bevy.

Changelog

Added an EnvironmentMapLight camera component that adds additional ambient light to a scene.
StandardMaterials will now appear brighter and more saturated at high roughness, due to internal material changes. This is more physically correct.
Fixed StandardMaterial occlusion being incorrectly applied to direct lighting.
Added FallbackImageCubemap.

Can you link the scene you used in the second screenshot? I know it was one of the gltf samples, but just to make it easier for people to reproduce

Overall, code looks good, I can't comment on the math in the shader though. I'll try to go over the reference material at some point.

Can you link the scene you used in the second screenshot? I know it was one of the gltf samples, but just to make it easier for people to reproduce

The scene is at the following link. If you want to reproduce the screenshot exactly, make sure to turn off all direct lighting, ambient lighting, and tonemapping, and enable hdr. https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/MetalRoughSpheres.

Overall, code looks good, I can't comment on the math in the shader though. I'll try to go over the reference material at some point.

Shader math is exactly taken from the multiscattering paper, and unreal's mobile rendering blog post. I've changed basically nothing from them. Should be entirely correct, assuming I didn't make any more copy paste errors :) (and assuming using perceptual roughness in the places I did is ok, which I believe it is, depending on how the environment map is generated).

For the most part I'm happy enough with the Rust code, except for the DrawFunction thing. Having to make a second DrawFunction, and have an ugly if statement to decide between them is kinda gross. Doesn't seem like a great way to do it, and I'm open to ideas on how to improve it. This was sadly the best I could come up with.

I would also love suggestions to improve the docs. I don't think I did a particularly good job explaining environment map lighting.

JMS55 · 2022-12-30T17:38:15Z

I'm probably going to rename EnvironmentMap to EnvironmentMapLight, to indicate it's a lighting component.

I'm going to prepare a different texture setup with a lower resolution (and so fewer mip level) diffuse texture which doesn't need the resolution, and use the space saved to have a higher resolution specular texture where it is needed, plus try to make the specular texture rgb9e5 to trade some precision for resolution, with @DGriffin91 's help. I'll make a PR against your branch or send you the files asap.

I like this renaming. :)

@JMS55 for the CI look at what the skybox example does in the top level Cargo.toml. You should be able to specify required features for an example.

I did that already, it doesn't seem like enough for the CI :/

## How This Works For the Bevy 0.10 release blog post (and for the first time ever), I'm publicly opening the doors to other people writing blog post sections. Specifically, if you worked on a feature in a substantial way and are interested in presenting it, you can now ask to claim a section by leaving a comment in this PR. If you claim a section, submit a pull request to the `release-0.10.0` branch in this repo. For the next week, we will be filling in sections (the release target is Saturday March 4th). Please don't claim a section if you don't plan on completing it within that timeline. Also don't claim a section if you weren't an active participant in the design and implementation of the change (unless you are a Maintainer or SME). I will claim any unclaimed sections. Try to match the style of previous release blog posts as much as possible. 1. Show, don't tell. Don't bombard people with information. Avoid large walls of text _and_ large walls of code. Prefer the pattern "byte sized description of one thing" -> "example code/picture/video contextualizing that one thing" -> repeat. Take readers on a journey step by simple step. 2. Don't use up reader's "mental bandwidth" without good reason. We can't afford page-long descriptions of minor bug fixes. If it isn't a "headliner change", keep the description short and sweet. If a change is self describing, let it do that (ex: We now support this new mesh shape primitive ... this is what it looks like). If it is a "headliner change", still try to keep it reasonable. We always have a lot to cover. 3. In slight competition with point (2), don't omit interesting technical information when it is truly fun and engaging. A good chunk of our users are highly technical and enjoy learning how the sausage is made. Try to strike a balance between "terse and simple" and "nerdy details". 4. When relevant, briefly describe the problem being solved first, then describe the solution we chose. This contextualizes the change and gives the feature value and purpose. 5. When possible, provide visuals. They create interest / keep people hooked / break up the monotony. 6. Record images and videos at the default bevy resolution (1280x720) 7. Provide an accurate listing of authors that meaningfully contributed to the feature. Try to sort in order of "contribution scale". This is hard to define, but try to be fair. When in doubt, ask other contributors, SMEs, and/or maintainers. 8. Provide numbers and graphs where possible. If something is faster, use numbers to back it up. We don't (yet) have automated graph generation in blog post style, so send data / info to me (@cart) if you want a graph made. ## Headliners Headliners are our "big ticket high importance / high profile" changes. They are listed briefly at the beginning of the blog post, their entries are roughly sorted "to the top", and they are given priority when it comes to "space in the blog post". If you think we missed something (or didn't prioritize something appropriately), let us know. * ECS Schedule v3 (previously known as "stageless") * Partial Android Support * Depth and Normal Prepass * Environment Map Lighting * Cascaded Shadow Maps * Distance and Atmospheric Fog * Smooth Skeletal Animation Transitions * Enable Parallel Pipelined Rendering * Windows as Entities * Renderer Optimizations * ECS Optimizations ## Sections These are the sections we will cover in the blog post. If a section has been claimed, it will have `(claimed by X)` in the title. If it is unclaimed it will have `(unclaimed)` in the title. Let us know if we missed a section. We don't cover every feature, but we should cover pretty much everything that would be interesting to users. Note that what is interesting or challenging to implement is not necessarily something that is relevant to our blog post readers. And sometimes the reverse is true!
