Trying custom shaders in Godot 3.2, include Area light shaders

I made it as test project(another one ye). and can share it now

Holy moly!!!! That is amazing. One of the best I've seen in Godot, or maybe the best.

I'm definitely gonna have to look through your code and maybe steal something ;)

Cheers.

thanks some code is not my, like area-light shaders, all links in shader code, you can check files area_lights/floor.shader and area_lights2/floor_area.shader original links listed there.

some of used shaders can be under CC non commercial license, check it before use, my code can be used as you wish, feel free to use it.

This needs to be in Godot 4.0! ... It's plugin time! Haha, JK. I'm not going to make a plugin out of this. Not yet anyway

And one more thing. That tube light in the demo. Its shadows were baked, right?

When you say area lights you mean mesh lights, right?

yes those lights are backed, in Blender cycles orange textures in folder arc/orig_red

well I do not want make it plugin, you can feel free to do with it anything you want (if original shader license allow it, my code can be used as you wish)

It's fine if you don't want to make it a plugin. I was just saying that because that's what I did last time with your Volumetric Lights demo. I'm still very impressed with that demo by the way; especially since it's running in GLES2! You know it might be possible to increase the precision of the shadow map by packing 24-bit depth into the 3 8-bit color channels, but I haven't thought through that much.

if you mean Polygonal area light, no its not for Polygonal you can check this https://github.com/bad3p/PAL/blob/master/Docs/PolygonalAreaLights_09081016.pdf (obvious problem-it way too slow because it do literally raytracing for full-mesh geometry in every fragment of pixel shader on surface that it light.... this is not good for real production usage, I wont implement it, way too slow, no reason)

in my project only Sphere-light source, Tube light source and quad source. quad source light from https://eheitzresearch.wordpress.com/415-2/

That's really cool! I didn't even know it was possible to code your own lights in Godot.
