(Webgl2 / WebGPU support) A better outline shader than the one that already exists on the C3 addon stack exchange.
That's fair. My own personal goal is to use something more reliable than the built in emboss effect, as I find it prety limiting. Where if one could control each edge of a rectange in terms of color and thickness of outline, I think that could have a tonne of applications and possibilities.
On a side note, any advice for someone to get started making their own fx plugins? I've been thinking I should start looking into it, but haven't found much on how to get started.
I wrote a short blog post about that a while ago:
construct.net/en/blogs/skymen-13/write-effects-construct-1538
It's a little outdated since now the SDK has changed a lot, including WebGPU and WebGL2 shaders, but still I'd say it's a good starting point.
I would also use c3IDE2 to set up a new dev environment for making shaders
