Hey there, we got a new pre-compiled release of the Flow Graph plugin for Unreal Engine!
It's the first release for UE 5.8.
The changelist isn't that big, but you should resave your Flow Graphs! The next release will remove old Data Pins code.

Unreal Engine 5.8 performance highlights article is live! Focusing on the most interesting changes affecting performance, profiling, and optimization.
New features for profiling with Unreal Insights, tons of shader permutations improvements, and many useful new CVARs and changes that a buried in the full release notes. Find all highlights below:

UE 5.8 finally fixes the default texture issue in your master materials!
Until now, any referenced texture in the base (material) material would still be loaded for Material Instances, even if overwritten in all instances. Fixed in 5.8 and can be controlled using r.Material.StripUnusedDefaultTextures
Here's the link to the Release Notes. You'll also find links to download the pre-compiled plugin.

Epic Gamesの言語「Verse」の公式ドキュメント“Book of Verse”、読んでみると発見が多い。気になったところを少しずつ紹介していきます。
まず面白かったのが「すべてが式」という考え方。
普通の言語の if は値を持たないけど、Verseは if も for も"答え"を返す。
だから言語まるごと算数みたいに、答えを部品として組み合わせて書ける。

A number we've seen in our dreams 🥹
This studio was the dream of specialists who left leading studios to settle near the Beskidy Mountains. Many called it foolish, but look at us now! What started as a small collective of industry professionals grew beyond our imagination.
Since then, we have created Seven: The Days Long Gone and our magnum opus, The Thaumaturge. The latter is averaging Very Positive reviews on Steam ❤️ Proving it’s possible to create great entertainment in a supportive work environment.
Thank you, Fool's Theory team! Your drive and talent made this growth possible. Here’s to the next chapter 🥂
A compact summary on how useful will be these new tools and DX12 updates.
Especially worth to read if rendering isn't your specialization and you couldn't review new tools on your own.
New plugin added to the Unreal main branch. Enables one of the productive ways of working with AI-assisted coding.

There's a new pre-compiled release of the Flow Graph plugin for UE5! It's the first release for UE 5.7.
As usual, this is a community-driven release. You will find a lot of improvements introduced by teams using Flow in production.
Big kudos to Riot Games! <3

I can’t believe I only just now found out about this four years late while trawling through settings, but windows terminal has (literally!) “Quake Mode”, where win+backtick/tilde opens/closes a terminal at the top of your screen.

When writing shaders in HLSL, be it in Unreal Engine 5, Unity, or any other engine for that matter, it is useful to remember about two intrinsic functions: 𝗿𝗰𝗽 and 𝗿𝘀𝗾𝗿𝘁.
Function 𝗿𝗰𝗽(𝘅), short for "reciprocal", simply calculates a reciprocal, that is the expression: 𝟭 / 𝘅.
Calling rcp in your shaders will generally be faster than calculating 1/x directly. So if you do a lot of divisions this might make a performance difference.
A sister function to rcp is 𝗿𝘀𝗾𝗿𝘁(𝘅), short of "reciprocal square root". It calculates exactly that - the reciprocal of the square root: 𝟭 / 𝘀𝗾𝗿𝘁(𝘅).
Same logic applies here as with rcp, that is calling rsqrt will in general be more performant than calculating 1/sqrt(x).
These two functions in general will result in faster code although this can happen at the expense of precision, so when using them always profile and examine the outputs closely.
Now have a look at the example in the attached image. It shows two ways of normalizing a vector in a UE5 material. One is via the standard 𝗡𝗼𝗿𝗺𝗮𝗹𝗶𝘇𝗲 function, which under the hood calls the standard HLSL full-fledged 𝗻𝗼𝗿𝗺𝗮𝗹𝗶𝘇𝗲 function.
Then, below that, is an alternative which normalizes a vector by:
- calculating the squared length of a vector
- multiplying the vector by 𝟭 / 𝘀𝗾𝗿𝘁(𝘀𝗾𝘂𝗮𝗿𝗲𝗱 𝗹𝗲𝗻𝗴𝘁𝗵)
Why this works?
Because the expression 𝟭 / 𝘀𝗾𝗿𝘁(𝘀𝗾𝘂𝗮𝗿𝗲𝗱 𝗹𝗲𝗻𝗴𝘁𝗵) is equal to 𝟭 / 𝗹𝗲𝗻𝗴𝘁𝗵, and when we multiply the vector by the inverse of its length we are normalizing it.
To sum up: if precision is important for your case, use standard normalization (𝗻𝗼𝗿𝗺𝗮𝗹𝗶𝘇𝗲 function in HLSL).
If precision can be sacrificed a bit then use 𝗿𝘀𝗾𝗿𝘁.
Always profile and inspect the outputs carefully.
