I already knew most of this, but I like watching concise and efficient tutorials, YT is so full of "tutorials" that are poorly produced, non-narrated, and often just timelapses with no clear instruction. Your teaching style and content are perfect for this type of subject. Looking forward to more tutorials from you.

Subscribed. Love the attention to detail and the speed you cut a path through the subjects. feedback - as a UE5 noob, at 1:58 you say "We're going to double click it to open it". Wiggling the mouse where I'm supposed to click would have helped, the mouse pointer had disappeared. It took a while to figure out you were talking about clicking the Graph section. I tried double clicking the element in the viewport, the item in the outliner, the line items in the details pane. What I finally found was I could click the PCG component line just below the instance line and the graph attribute was right there to double click.

So should I be using Procedural Foliage like in the Save Hours! video or do I use the PCG framework here? Is PCG more up-to-date or does the other one have foliage-specific features not shown here?

@azielarts 4 ай бұрын

Hey! Great question. I would personally go with PCG at this point. Both are valid for sure. Procedural foliage will spawn foliage and PCG will spawn actual meshes, so there might be some technical reason why you would go with one or the other. I personally use PCG because it is the newer tool and has more power in what you can achieve with the system. Up to you though:)

@user-im5hm2ty6d 11 ай бұрын

Hello I have seen your other video which is slightly older about the old procedural foliage object and I love it mainly because of the nature logic it uses. Things like seed spread and stuff. I now would like to use pcg as it is more versatile in the stuff I can spawn (villages, houses, Rocks, etc) but I didn't think about the nature logic aspect. I then found out how important it actually is. my pcg graph just basically had a surface sampler a transform points and a static mesh spawner it works but looks like the grass is placed in a grid. Do you know any way to simulate seed spread and stuff like that?

@azielarts 11 ай бұрын

Hey, yeah great question. You can achieve a similar result with PCG, it just takes a bit more set up. For example you can spawn a bunch of points, then you can use the position of those points to spawn a second grid of points that gradually get smaller based on their distance from that first point. With a bit of randomness thrown in, you will get something similar. PCG is indeed more versatile as you said, but because of these you need to build that nature logic from scratch as opposed to having it built in. Does that make sense?

So glad you found it helpful!! For me it runs smoothly, but that will really depend on your computer. The actual sim part is not heavy, and when you have something you like you can bake it in. It more just comes down to standard optimization of meshes and textures.

sorry for the question. it may sounds strange but why to use density if you already have a "point per square meter" if you want to lower number of meshes?

@azielarts 10 ай бұрын

I love questions! you are right you can use both, using the density filter lets you sample the same stream of points for multiple types of meshes instead of resampling the landscape every time. It is more of an efficiency thing. As you get more in depth with pcg you will start to look for ways to simplify the graph and reuse points. Does that makes sense ?

I finally bit and tried PCG with this video and holy crap it's cool! But performance sucks! When I was done with this video I was getting 30-40 fps. When I recreated it with foliage painter next to the PCG volume, my fps (when the PCG wasn't on screen) was 120. I run a 12900KF, 3080ti with 32Gb RAM. Am I missing some optimization, or is this made with beefier rigs in mind?
