Hey everyone, I posted a similar question, but I wasn't specific about the kind of
TileMap I was using. Basically I want to transform the result of
get_used_rect() into a result I can use to stretch a
TextureRect over the entirety of my
I've been learning about matrix transformations in order to solve this problem, but It'd be nice if anyone can give a solution.
I'm trying to create a fog of war shader. I have almost everything figured out, but I can't get the
TextureRect (which is rendering the shader) to stretch accross my isometric
TileMap. Does this sound like the right approach? I'll post a repo of the project soon.

Edit 2: figured out how to the get the correct size. I erroneously thought that the size of the TextureRect should be multiplied by the
cell_size, not the case. The actual number to multiply the TextureRect before the transform is made is by what the tile size side would be if you made the inverse transform on it (basically flattening it). In the demo that number is something like
