Do You Want to Access PCG Points In Blueprints?

[@rvakato]

I really like your PCG series video. Very useful always. Advanced tricks but easy to understand. Thanks!

[@Procedural_Minds]

You're very welcome! :)

Thank so so much for this video, you can't imagine how helpful that was to me, I've spent the whole afternoon looking for a way to set a dynamic material instance for my PCG spawned meshes, and I believed that you simply couldn't, Now you've restored my faith in my project, Thanks again

[@Procedural_Minds]

You're welcome. Glad you found what you were looking for. :)

[@aronforsure]

good stuff! love the PCG tutorials

[@Procedural_Minds]

Thank you, glad you like them! :)

Thank you soo much very helpful :D

You're very welcome :)

Your PCG tutorials are amazing, love them! At 2:25 you say that `actual blueprint gets the information after the generation has completed, if you want to gain access to the points at the middle, you woulnd't be able to do that quite easily` - It's actually what I need, what's the other way to get also points before end (before Density Filter)? I was thinking about subgraphs

[@Procedural_Minds]

You can get the information at any point as long as you're using them inside the PCG graph itself. But the BP won't get the information until completion unfortunately.

Thanks a lot, a really useful and unique info

You're welcome, glad you found it useful. :)

nice as always :)

Thank you very much! :)

What about in PCG Blueprint Elements? I can't get them to print

[@Procedural_Minds]

It's because they're not children. You'd need to use something like Get All Actors of class. Or on creation they can use an event to send their info to something like the game mode that'll gather all of them in a single array.

[@SOPHIE.BRAMLEY]

ahah got it, would you be able to show how we take this into sequencer to modify there

[@Procedural_Minds]

I don't personally ever use sequencer, sorry.

I need help. If I have two landscapes. How do I pick which landscape my PCG graph would sample. It seems to favor the first landscape I added in the level, and it ignores the second one? How do I force it to use the second one or both if possible. For anyone that can give me an answer, thank you in advance.

[@Procedural_Minds]

I believe it's designed to use the first landscape. I would check the Get Landscape node in PCG to see if it has an option to select a different landscape there. It's possible it only supports the one.

[@sonic55193]

@@Procedural_Minds Thank you for your answer. Much appreciated.

[@Анон-к4я]

I will be grateful if you can answer. How can I pass some parameters from PCG to spawned actor so that it takes this parameter into account in its logic in construction script (I hope it's clear)

[@Procedural_Minds]

You can pass variables to and from it using the PCG Parameters, which are just variables. In the first episode of the building series I use them, as well as in the somewhat recent tutorials as well.

[@Анон-к4я]

@@Procedural_Minds I wanted to find out something else, the video shows a way to pass parameters to the root actor. I would like to find a way to pass any variables to the actor that was created through the PCG node spawn actor

[@Procedural_Minds]

@@Анон-к4я If by root actor you mean the original blueprint, then that's exactly what I was referring to.

[@SOPHIE.BRAMLEY]

the get instance count isn't appearing for me...

[@Procedural_Minds]

Are you dragging out of the same node as I am with context sensitive on?

[@saharyousefi7128]

make sure you are using "Get components by class" node and not "Get component by class".

[@THAblackful]

The title is wrong. You are not accessing any PCG point in the blueprint. You spawn the meshes as ISM and then get the child ISM and run a process for every instanced mesh. That is totally different to get the actual PCG points, which is what I'm trying to do and has nothing to do with the process in the video. Is a good video though, but it leads to confusion. If there's any way to actually access the PCG points and access thins like attributes once the graph has been executed that would be handy. If you found a way I will very thankful if you share it. Is still missing a lot of documentation I edit myself, using the PCGData you set as input of you function. then breaking it into PCGDataCOllection, running a for each tagged data and then casting to PCGPointData. you can actually do it :D

[@Procedural_Minds]

Yeah, you have a good point about the title. Unfortunately I don't think there's any way to access the attributes mid construction in the blueprint. But you can use custom nodes in the PCG graph itself to trigger BP functions. Depending on what you need, that might get you the result.
