1 year ago I saw about hextiling in BGFX demos, it's a neat technique. It's however more expensive than what I'm doing currently, I use only 2 texture samples, while hextiling seems to use 3 + computes a lot more stuff (so with PBR textures: x2, using 4-channel splatmap: x4, so 24 fetches. And with triplanar: 72 fetches, not even counting heightmap fetches and internal Godot fetches)
Many options were asked for in shaders of this plugin, and I wish to expose options. Just like Godot exposes myriads of options in its materials. But Godot 3 achieves this by dynamically changing preprocessor macros, which isn't a thing for user shaders. That means if I wanted to have options, either I have to litter shaders with if inside (which is very bad for performance when there are many) or I have to copy/paste all the shaders for every combination of options, which is unmaintainable.
It might be easier in Godot with preprocessor support, but macros can't be toggled from the inspector so it would still require many shader variants. Or it would have to be global to the entire game by writing the symbol in project settings to enable it.
(I said this many times in about every issue asking for shading options but I repeat it anyways^^")
This would be a cool enhancement still.

Is your feature request related to a problem? Please describe. The existing way for tiling reduction still gives rather noticeable tile seams.
Describe the solution you'd like Use hex tiling mechanism instead, like in this C code https://github.com/mmikk/hextile-demo
