Mastering Procedural Open World Creation with PCG and Unreal Engine 5.2

[@januszkunowski2963]

In Unreal 5.3 "Density Noise" is "Attribute Noise"

[@CGDealers]

I'll pin your comment as I've got this question very often.

[@ArtemiseArt]

Thank you!

Thank you!))

[@alexanderiliev6398]

Thank you so much!!!!! You are a saviour! :)

[@qhhuetran]

Changes in UE5.3 To get "Mesh to Points", choose "execute blueprint" --> select Meshtopoints in the blueprint element type Great tutorial btw, very concise!

[@CGDealers]

Thanks for sharing those changes! PCG will keep changing in the future for sure.

[@Redvil01]

We'll be looking out for more nodes baked into other nodes for sure. xD

[@cookieClarke]

Unreal 5.3 "Get Actor Property" replaces "Property to Parameter" by the looks. Great tut btw:)

[@SmkAslt]

This dude is fucking incredible. Thanks man. Folks like me with limited resources and time need more people like you. I hope as many people as possible sign up for your patreon.

[@CGDealers]

Thank you so much for the kind words! I hope my videos will help you out in your game dev journey! Good luck!

Truly the best On YT. Patreon Supporter as of 2 days ago when I found you. You have helped speed up my project 10 fold. Great work.

[@RubenKP]

If anyone else had troubles debugging the Density Noise at 54:06 you gotta Open PCG_BasicSpline and Connect the Output of the last "difference" block to the output block there. After I did that it worked for me. :)

[@RubenKP]

I just saw at 55:46 that you didnt need to connect the outputs i guess? no idea why i have to do that

[@RubenKP]

Ahhhh okay i just followed along further, you are doing that as well now!! :D :D

Glad you like them!

[@ParikshitBhujbal]

@@CGDealers in PCG Forest creation overview , you have used nodes like Union, ApplyDensitytoheight and projectpointstolandscape, the last one is easy to understand but you never tell us what Union and ApplydensitytoHeight nodes do earlier in the video? I did not understand why you used them and what they do.

[@trendyourdays7382]

for those it can help if you stuck at 54:06 and cant see the debbug try to duplicate your PCG_basicspline and use the new one in the pcg subgraph plus dont forget to connect the Outpout to the last Difference node

[@Freg-ld2lo]

Wow, thank you. This is exactly what I was looking for.

[@CGDealers]

Hope it helps!

[@brodinskii]

For those who have the issue around 56:00 min in the video, where the boxes won't show up after you press Debug on the PCGI Scatter Graph. If you are running 5.3 or higher, go in to your Sub Graph and turn on and off debug or disable -> enable the "FILTER TO POINT" node which UE creates on auto between the Basic Spline PCG and the Attribute Noise. That did the trick for me!

[@renobrecords]

I'm teaching myself game dev and wanted to tackle progen bc I think it's so cool. This is easily one of the best tutorials on PCG. Subbed!

[@Sithrak]

Hi, awesome video even more so it's an amazing masterclass on PCG as a whole. Thank you! As I'm watching this after a few months, there's some slight changes that would be a great addition as comment overlays during the video :) 1. As @RubenKP mentioned, passed over the Output node for PCG_Spline 54:06 [Add the last PCG Spline "Difference" Out node to the Output] that time would work perfectly as its right before your debug 2. There is no more "PropertyToParamData" node in the Param section, but there is "Get Actor Property", which works the same 1:04:42 (it shows an error on the node, but seems to be working anyway)

[@CGDealers]

Thanks for the update. As PCG is still under development more stuff will change in the future :)

[@Kobraisten]

it most likely shows an error because you have more than 1 pcg instances placed on the map

Edit - I am incorrect, BP_Element_MeshToPointsWithColors seems to work! (I was originally using different meshes between nodes by mistake) I'm having trouble at 1:13:12 - I cannot find the "MeshToPoints" Node. I have tried both "MeshSocketsToPoints" Under "Spawner" list, and the "BP_Element_MeshToPointsWithColors" under the "Sampler" list, but neither seem to work (I have set debug on them as well).

It is duable but still PCG is experimental and not ready for shipping a game with it. In my opinion.

at 56:05, My points dont seem to be comming through when I debug the copy points node. In 5.3 it auto sets up a 'to point' node to change the input to point, when debugging the 'to point' node I can see the white boxes, but when debugging copy points, nothing is comming through and it seems to be breaking the subgraph as it cant come through, anyone else encountered this?

you might need to use lower quality textures and 3d assets. they can eat up a lot of VRAM and make the fps plummet. and possible make the nanites fall of in the amount of triangles they can use after a certain distance, there should be a setting for that in the blueprint for the material/asset.
