After research, an AO map might be a good addition: - SSAO is costly and can be ugly (not so easy to get right) - the AO can be added as the blue channel of the MR map - with improved ambient/indirect lighting it becomes an essential effect - the lack of dynamic AO is probably less of an issue with ...

Performance/optimization is probably one of the most filled with misconceptions topic in programming (or other areas).

LÖVE is fine.

I don't know about an AO map, that would conflict with a potential SSAO; but it's possible. For now each material requires 4 textures, I don't want this number to grow (or the complexity), but there are slots to take for this kind of effects. Normal maps are transformed in the material pass to follo...

It's amazing right ? It's a peculiar workflow for 2D, it has some drawbacks that I'm trying to solve (like anti-aliasing/filtering). I love pre-rendered graphics and 2D is perfect for that; this is like another level of baking. I have found similar projects like this one . I can explain more how it ...

Hi, love-DPBR is a Deferred Physically Based Rendering library. The idea of using "3D" techniques for "2D" (ultimately the same on the screen) is not new, but I wanted to push this further and I can already see many possibilities. It's at the frontier between 2D and 3D, which exp...

I added compiled libraries for Windows: https://github.com/ImagicTheCat/love-we ... aster/dist

For other platforms, compiling WebP would probably be a part of the app building process.

It depends on each target, there is no (unfortunately) consistent cross-platform automated process to build binaries. There are more build systems than Lua OOP libraries and it's still a nightmare.

What are your OS/arch targets ?

This is the drawback of an external library with the FFI and why native support is important for LÖVE where users probably expect everything bundled with the engine. This is meant to be used in a project, but you need to compile/get the WebP shared libraries for each target, as you would compile/get...

Under a GNU/Linux distribution, you probably just need to install the WebP library on the system. It seems that only static libraries for Windows are given on the WebP website, so you need to compile the shared libraries. I could add the DLLs into the project, but I think it would be better to let p...

I created a pure Lua WebP library (using LuaJIT FFI) which implements the discussed features: topic
