Miku Fan-Made Free MikuMikuDacne Renderer

The repo still under positive developing, any community contribution is greeting and welcome.

​ flower engine is a vulkan starter friendly render engine.

​ There is not too much wrapper, so every beginner can easy to find out how it work.

​ The render passes are some isolated render functions, pretty easy and clean to build a renderer.

How to build

Just download the project, all dependency here is ready.(Maybe need install VulkanSDK 1.3 and update driver).

There exist three branch, dark branch is clean developing branch. Main branch include MMD features. Release branch is stable legacy branch.

Dark branch design UI and realtime rendering in 4k, so run in 1k or 2k, maybe need to change configs smaller:

r.ImGui.FontSize
r.ImGui.IconSize

The dark editor support FSR2, use command “r.viewport.screenpercentage” to downscale the render percentage to get better performace.

Some mesh art asset can download here:

https://drive.google.com/file/d/1aRkqTKuqAAmkOSmfe6BSnnycj6HnJaIi/view?usp=sharing

and unzip then import mesh. It need some time to cook asset.

When first time open the editor, need something to compile shader variants, and it will cache if next time reopen.

Current Features

1. Gpu dispatch mesh rendering pipeline.
2. Async texture uploading pipeline.
3. Physical-Based rendering and shading.
4. Ground-True approximate ambient occlusion.
5. Stochastic screen space reflection.
6. Precompute atmosphere.
7. Gpu dispatch sample-distribution cascade shadow map.
8. Temporal super sampling.
9. Postprocessing effects.

How to build

​ Exist two branch, main branch is developing and may exist some bug, release branch is stable branch.

License?

Hello,

I was wondering what the license of this repository is, as there doesn't seem to be a LICENSE file anywhere? Adding one would make the rules regarding how things can be used much clearer, and would also help with additional contributions.

Thank you for your work on this project.

Vulkan version?

I would like to know the vulkan version used? I used 1.2.176.1 compile error.

visual studio 2022 running failed

Hi, qiutang, I'm using Vulkan SDK 1.3.261.1, GPU RTX3080. Compilation is passed, but start in visual studio 2022 is failed. I've already updated GPU driver to newest, what can I do to solve this problem?

Compilation error (std::unordered_set<std::filesystem::path>)

Hi,

There is no standard std::hashstd::filesystem::path. (https://stackoverflow.com/questions/51065244/is-there-no-standard-hash-for-stdfilesystempath).

Project Plan, Roadmap, Reason.

Hi,

Glad to see you're working on a Vulkan high performance game/render engine.

We are currently looking to hire or fund development of such game/render engine and we wanted to learn more about your project and yourself.

1. What are your development goals or roadmap/features you plan to develop and if possible, approx. dates?
2. Why are you building your own game engine, in other words, what was lacking in other game engines, specifically Vulkan based engines or renderers?
3. Will this be made into a commercial project? Are you working full time on this?

These are just a few questions to get the ball rolling.

Cheers,
Einthusan
