Write a documentation page on creating good-looking 3D scenes

Looking at various social media, I keep seeing a lot of 3D scenes that don't look great and could easily be made to look significantly better with a little more work. For instance, when anisotropic filtering on textures isn't enabled in a desktop game (when it should almost always be in 2021).

In the long term, this relatively "amateur" appearance tends to give a bad image of Godot's 3D capabilities. This image may persist after 4.0 if people don't step up their 3D scene setup skills 🙂

However, I'm worried about this page not being general-purpose enough for the Godot documentation. There's a lot of engine-agnostic resources on creating good-looking 3D scenes, but also a lot of good Unity/Unreal Engine-oriented resources that Godot users may shy away from.

This would be similar to the Performance section we have, except that it'd be focusing on improving visuals instead. Sometimes, there would be performance tradeoffs involved in improving the visuals, but not always.

I wonder if this would suit a series of blog posts better. Visual appearance is highly subjective and varies dramatically from game-to-game. Plus as issues are resolved and new features are added, the doc would quickly become out of date and would be a nightmare to maintain.

If people aren't already looking over the various pages to see how lighting and materials should be setup, I doubt they're going to bother looking at this new page. That said, the 3D pages do need to be gone through and cleaned up. I think that would help creators significantly.

@skyace65 I disagree. If you have an article on better lighting with a specific demo project, I think it would help a lot of people to get more familiar with adjusting their scenes. Also having an article instead of the docs would still help a lot since it could still be parsed by search engines when searching "How do I improve lighting?" or "How do I make my game look good?"

I think with an appropriate setup and good SEO this is a very good addition.
Perhaps we can consider adding a way to directly "download preset" from this page?
