Unreal Engine 5.2 PCG Tutorial - Skyscrapers and Flowers Using a Single Custom Blueprint

[@0xJarry]

Amazing! Note for those looking for "Density Noise" its "Attribute Noise" in 5.3 atm

[@antoniosuarez7881]

it took me 2 days but finally make it, I completed the fully blueprint with all the procedural thing but I used meshes what I imported from Fusion 360 with DataSmith, so then the blueprint isn´t only procedural it is parametrized too. thanks this is a really useful and grate tutorial. I hope you continue doing this kind of tutorials

[@MichaelRoyalty]

That's a great upgrade! I'm pretty new to 3D work and Unreal, so I'm learning about all of this as I go. I'm definitely going to keep sharing as I learn.

car flowers. love it!

[@MichaelRoyalty]

I'm not much a modeler so I make do with what I've got!

[@kthxbye1132]

@@MichaelRoyalty I have a question. Can you check wether the generated meshes are Nanite?

[@AlanGordieJr]

I too am a fan of the car flowers featured here ;) Nice work, make more please

[@MichaelRoyalty]

@@kthxbye1132 How do you mean? Are you looking to check within the PCG graph and not spawn them if they're not nanite?

[@kthxbye1132]

@@MichaelRoyalty Nono, if you change the view from lit to -> Nanite triangle visualization, you can see wether the meshes are nanite or not. I experimented with this and found out that if you use the landscape spline with a Nanite mesh, Nanite won't be enabled on the deformed mesh.

Great tutorials, I wish you can do some explanation on separate video for PCGDataCollection in general. It would be really helpful to see in details, but still this gives a good direction to learn in depth! Thanks for sharing!

I'm so excited to try this out! Thank you!

[@indira4435]

okay - tried it on 5.4 - can't get the models to show up at the 7:37 mark :( I know input > landscape data changed to just landscape data and you can check off the height... and some nodes are different colors / in slightly different categories, but i was able to find the same things roughly. Let me know if you're open to discussing this! Otherwise - beautiful tutorial and I'll check out your other work

[@indira4435]

omg it was just the spline !! haha okay im gonna keep trying. disregard this for now. im having fun w this tho :3

[@MichaelRoyalty]

Great! Be careful when using blueprint nodes like the one I demo here -- I didn't understand all the nuances of working with point data, so I probably do it a little wrong, which can lead to strange errors and crashes.

[@ashoakenfold]

Interesting use of PCG. Haven't checked it out yet, but I think it's possible do something similar using a custom cloner (BP) for the new mograph tools in 5.4

[@WORLDSTORY-yg7np]

In Unreal 5.3, spline sampler On Interior are create internally when unbounded is true.

[@MichaelRoyalty]

Thanks for pointing that out! Yeah if your spline isn't sampling in 5.3 you probably need to set unbounded on it.

[@wtbuser]

I am getting a "Error: Invalid input data in VariableLoop" for all of the Actor properties being piped into the Copy Points node. Can't figure it out.

[@alexrybin3798]

Awesome channel man! subscribed. Only thing i still can't get, how do you connect spline from Blueprint to PCG. What if i have 2 or 3 different BPs, how i can point PCG to desired BP?

[@MichaelRoyalty]

The easiest way is to have a single actor with your pcg component and your spline. Then you just get spline data, pointed at self. For splines not on your actor you can find actors by class or by tag and import their spline components. Make sure to check the option to import multiple, and on your sampler you'll either need to check unbounded, or make sure your pcg's bounding volume fully encompasses your splines. Hope that helps! Side note, I think I've figured out how to do this natively in 5.3 using loop subgraph, which should be more stable.

[@DmitrySinditskiy]

this is good! thank you

[@PeoplesGaming]

Brilliant 👍

[@Mr_Dee]

Supercool!! But going to return to this tutorial after I upgraded my base BP and PCG knowledge :)

[@MichaelRoyalty]

Yeah, this one gets a little technical, and you might not have run into the problems it's solving quite yet :)

[@andresca1985]

i cant see the node input landscape at start, no show more nodes in input, why? i am using 5.4

[@MarioCola]

But how to sample a single point from a landscape without custom blueprints?

[@oussamachobah5339]

Is it normal that i can only create one window wall and it is always on a splining point

[@MichaelRoyalty]

You might need to change your spline sampler to sample on distance. I'm guessing you're currently set to sample on subdivision?

[@oussamachobah5339]

@@MichaelRoyalty nop its on distance
