After long adventures and frustrations with UGUI, I can say with confidence that reading the source code helps better than official documentation. There are many "not a Bug, but rather a feature by design" things, won't be fixed in current HorizontalOrVerticalLayoutGroup

To avoid using ForceRebuildLayoutImmediate or/and some manual update workarounds, the following approach works well:

Both "child controls size" checkboxes must be enabled and "child force expand" disabled for all ILayoutController (Horizontal, Vertical, also for nested ones), then to control the dimension of the objects you simply use the LayoutElement component (min, pref, flex sizes). As a result, any dynamic content is correctly aligned, regardless of the activation/deactivation/addition/removal of neighbors.

Note 1: There is no need for ContentSizeFitter component for GameObjects, that are first level children of any LayoutGroup. The main thing is to correctly set the checkboxes, as described above. However ContentSizeFitter may be useful for top level container, or children of children that are not directly controlled by any LayoutGroup.

Note 2: Minimize LayoutGroup nesting when possible. Layout rebuild is very expensive. More info on topic:

float val = smoothstep(_Radius + _Blend, _Radius, UVDistance) * _CellBuffer[i].z;

Smoothstep работает следующим образом: если переменная «UVDistance» больше, чем "_Radius + _Blend", то она возвращает 0. Если переменная меньше, чем "_Radius", то она возвращает 1. Между ними значения плавно интерполируются от 0 до 1.

C# Delegates with IoC Containers and Dependency Injection

An interesting article on how to replace one method interfaces with delegates, how to use them inside DI containers and unit tests.

Span

tl;dr Use Span to work with ANY kind of memory in a safe and very efficient way. Simplify your APIs and use the full power of unmanaged memory!

Important notice: async and await are awesome C# features. They make our life easier by solving a lot of problems and hiding a lot complexity from us.

But whenever async & await are used, an AsyncMethodBuilder is created. The builder creates an asynchronous state machine. Which at some point of time might put the parameters of the method on the heap. This is why Span must not be an argument for an async method.

Sprite Glow/Outline Shader Breakdown in the Shader Graph

Using Unity’s ShaderVariantCollection

Typical use of ShaderVariantCollection is to record the shader variants used during a play session from the editor (under Graphics Settings), save them out as an asset, and add to the list of preloaded shaders (again in Graphics Settings). Additionally, you could call WarmUp on a ShaderVariantCollection object manually.

World space UVs & Triplanar Mapping

This post includes an introduction to using the Position node to sample textures rather than using mesh UV channels, which is also the basis of Triplanar mapping. It won’t be super in-depth but will provide some example graphs to (hopefully) help beginners understand how this could be used!

Triplanar Mapping Texturing Arbitrary Surfaces

More in-depth article about triplanar mapping using shaders instead of the shader graph.

The usual way to perform texture mapping is by using the UV coordinates stored per-vertex in a mesh. But this is not the only way to do it. Sometimes, there are no UV coordinates available. For example, when working with procedural geometry of arbitrary shapes. When creating a terrain or cave systems at run-time, it usually isn't feasible to generate UV coordinates for an appropriate texture unwrap.
