I've updated my Designer Editor Mode plugin for UE 4.25. It's also (finally) out of beta. New features include a proper UI and a preview actor is shown before spawning! It's still free including source: unrealengineer.com/designer @UnrealEngine @UnrealDevs #ue4 #gamedev

Introducing FragCoord: My ultimate shader editing tool!

Hey I made a new thing - it's called Gradientspace Graph, and it's a C#-based NodeGraph Programming system that also supports inline C# and Python "Code Nodes". The NodeGraph Engine is MIT Open-Source and the Editor is Free. More details in thread...

@skx_doom That's really useful, can you explain how you did it? I was just thinking of hijacking one of the unused post process input texture slots and wrap that in a Material Node, but if there is a better way, I would love to know 😀

Made a new material node which samples custom "occlusion shadow" texture internally in Sky Creator, without any external assets. I never did this before, so are there any caveats to be aware of? Is this even safe?

Unreal Editor magnetism🧲 Annotate your meshes with connection points and they become magnetic. Also works with splines etc. Now on sale $9.90 (link in reply) #UE5

Funding: if your mid/large business uses Dear ImGui - and maybe you are approaching end of year budget/planning - please consider reaching out (PM/email) so I can help you help Dear ImGui !

Here's some cute bounding box functions for 2D shapes. A link to a longer list in the next post.

@skx_doom There is no way someone is making a game with volumetric fog but without your plugin. It is too good, really makes it look/feel more unified and coherent.

I think I can spot some SSFS there 👀

New update to Scythe, my Source 2 Hammer inspired level editor for Unreal Engine 5! New features below! 🧵(1/6)

@theredpix Why are the shadows so bad-looking? 1 cascade for the entire scene?

#UnrealEngine 5.6 Here is how one of my projects is performing. Tops at 1400fps with #Lumen on, 1080p native resolution. All my mats are on green and the whole logic is made on C++ (that allows for over 1000fps performance). Hardware: 4080S/9950X3D #gamedev #indiedev

I got tired of Unreal's debug drawing performance, so I made my own system today. Drawing +50M points just works now :) It's open source (link below)

Shipped yet another plugin today: the HDRI Browser hooks into the @polyhaven API to seamlessly bring browsing and downloading their CC0 HDRIs into unreal engine. #UnrealEngine5 #UnrealEngine #gamedev #indiedev

@AlanNoon Ahh, you need to have early access to play now, open beta starts tomorrow

@roelbartstra Mine all have locks

Doing an encore of my "Fast As Hell: idTech8 Global Illumination" lecture at Siggraph 2025 Advances in Real-Time Rendering in Games. Excited, haven't attended Siggraph in a while! advances.realtimerendering.com/s2025/index.ht…

MeshBlend is finally here! 🥳 So proud to finally release what I've been working on for 16 months! MeshBlend brings next generation blending to Unreal. Easy to use, fast and great quality! Available on @fab for @UnrealEngine now! #gamedev #unrealengine #ue5

UE5 physics simulation and instancing plugin will be available in a few hours! 5.4 5.5 and 5.6, website will also slowly come to live foliagetools.com

The slides from my Unreal Fest talk are now online! victorcareil.com/unreal-fest-ba…

The full code is available on github and shows how to hook into the Nanite visibility buffer from a plugin: github.com/Phyronnaz/Mate…
