Unreal Engine 5.7 just released and tomorrow I'll be part of the cast to talk a bit about new features in this version! Excited to show some of the new features of PCG the team has been working on :D See you there :) https://www.youtube.com/live/3PQga-2vLm4?si=9tHdOqibze1oXHFY12 Nov 2025 22:24 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3m5hoxnj7ps2xhttps://bsky.app/profile/amathlog.bsky.social/post/3m556bghjgc2uMy #PCG presentation at @everythingproc is finally out :) Focusing on PCG at runtime, impacted by gameplay, with a revisited Snake. It also shows that it is possible to have it at runtime on Mobile. https://www.youtube.com/watch?v=5YR-xUwNRiI #UnrealEngine08 Nov 2025 17:59 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3m556bghjgc2uhttps://bsky.app/profile/amathlog.bsky.social/post/3m4vh2ldozs2gReturn of #UE5 #PCG tip of the day! If you ever tried to use Transform Points and were sad that you can't provide a Rotation Min/Max for each point, here is a solution! The gist is to generate a random value for each point, then apply Lerp between max and min provided as attributes!05 Nov 2025 16:15 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3m4vh2ldozs2ghttps://bsky.app/profile/amathlog.bsky.social/post/3m46hmxxgnk2hHey there!

New #UE5 #PCG tip of the day! You can send data from PCG to the material for each instance. For example I can read $Color.RGB on each point and send it to my custom "ColorMaterial". Static attributes (with $) only work in 5.5, but dynamic attributes work in previous versions.10 Jan 2025 16:17 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lfflrrkvkc2khttps://bsky.app/profile/amathlog.bsky.social/post/3lek5wh25ic2cCome come 👀 [contains quote post or other embedded content]30 Dec 2024 18:27 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lek5wh25ic2chttps://bsky.app/profile/amathlog.bsky.social/post/3lcyqumpdwk2d#UETips #PCG Let's see how we can combine the material override with the spawn actor! On Spawn Actor, you have the option to specify Post Spawn functions. If I create a custom BP, inheriting from StaticMeshActor, with 2 materials variables, I can have a Post Spawn function that will set them. 1/211 Dec 2024 02:53 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lcyqumpdwk2dhttps://bsky.app/profile/amathlog.bsky.social/post/3lcq7eqoi5s2sJust finished Until Then, definitely one of my GOTY!

On the Static Mesh Spawner you can specify multiple material overrides, one per material slot on your mesh. In this example, I select randomly materials for the leaves (Material ID 0) and trunk (Material ID 1)! 🌈28 Nov 2024 15:18 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lbzegqyhxk2ohttps://bsky.app/profile/amathlog.bsky.social/post/3lbxpjhcx2k2t#UETips #PCG In the tutorials I've shown how we can parameterize the spawning of meshes, to allocate them randomly. But we can also use that technique to spawn static mesh actors with this mesh! You can use the "Spawned Actor Property Override Descriptions" on the Spawn Actor node (1/2)27 Nov 2024 23:31 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lbxpjhcx2k2thttps://bsky.app/profile/amathlog.bsky.social/post/3lbklhc3mj22i#UE5 #PCG Another tip of the day! If you have another system that generates a list of positions and you want to import it in PCG and convert it to points, you can do it like this! I have a simple BP that generate random positions and a PCG that spawn cube at those locations.22 Nov 2024 18:14 +0000at://did:plc:yj4wd7xav5o7rlwl64jniz3t/app.bsky.feed.post/3lbklhc3mj22i
