Unreal Engine 5.2 PCG Tutorial - Extrude Logos From 2D Images

[@tehwayniac]

Does the initial texture imported need to have alpha? I've tried png both with and without and keep getting either nothing or a big white square rather than my logo. Have also tried using the both options suggested in the texture compression dropdown netting the same results.

[@MichaelRoyalty]

Sorry, I forgot to mention this in the tutorial! In my example image, the color channels exactly match the alpha channel, so it doesn't matter which channel I sample. In your case you may want to update the Get Texture Data node to sample from a different color channel. The color channel selection is directly below where you select the image.

Thanks for the Lesson, at the end I was expecting HI ,but it was Enjoy Text . really enjoyed.

[@MichaelRoyalty]

I'm glad you liked that bit of silliness! It was a fun trick to put into the video

[@scottcourtney8878]

Nice! Now I know what you were doing with all those texture format experiments. :)

[@MichaelRoyalty]

Now you see my master plan! :D

[@lukegordonharris]

Great stuff, you’re putting out so many of these recently! Very much appreciated. This one has so many valuable techniques!!!

[@MichaelRoyalty]

Thanks! It was nice doing a less involved video after the longer pixels one, that's for sure!

[@getschwifty864]

Loving these PCG lessons!

[@AIMingMusic]

Super helpful. To the point. Earned a follow!

[@Drahoslav_Lysak]

Awesome :)

Amazing tutorial :) I also had problems with the texture image. It was too big (1024 x 1024, Number of Mips: 11), I reduced it to 200 x 200. The Number of Mips was then 1. The "Density Noise" note no longer exists in 5.3. But it also works without connecting the "Static Mesh Spawner" directly to "Density Filter".

[@MichaelRoyalty]

Interesting! I didn't have a problem with a larger texture, so maybe it's the number of mips? At any rate, I'm glad you found a fix! I want to say "Density Noise" is now "Noise" in 5.3, and you just point it at $Density. I had to stop using 5.3 preview after a couple crashes that made my scenes unopenable, so I'm not 100% certain on that.

[@unrealopenworld]

@@MichaelRoyalty It's bad if you can't load the project anymore. I've had it many times too, I always make a copy, of the copy, of the copy ;) In 5.3 there is only "Attribute Noise" and "Spatial Noise", no "Noise". But it also works without "density noise".

Thank you for this awesome tutorial! Concerning the PCG Buildings: I extended the graph to provide more variance but I don't know how I can make it so the buildings have different colors. I was thinking about getting the color attribute of the initial points but I would have to create a material instance for the static meshes per each building and somehow drive the material through the point attribute. Do you happen to know anything about this?

[@lukegordonharris]

Yup you can do it through per instance custom data. It’s a bit complicated to explain in a comment but on a static mesh spawned if you set the instance packer to the one that has ‘attribute’ in the title, a new section down the bottom appears where you can pick attributes in to each instance and access them in the material

[@pinsandneedles8562]

​@@lukegordonharrisThank you so much! I was looking at the instance packer but I must have missed this. Been thinking about this issue the past couple days haha

[@MichaelRoyalty]

@@pinsandneedles8562 I'm just learning about passing attributes along myself thanks to Luke! Make sure you set the attribute before you copy the points upwards -- Since the buildings are just a single point at that point, setting it there will make the attribute carry on down to all of the other points on the building.

[@pinsandneedles8562]

@@MichaelRoyalty Yeah, works like a charm now :D

[@pinsandneedles8562]

I don't know if you guys could help me again with this, but: I tried to make a pcg for spawning these japanese alley houses (the ones lined up without any space between them) and for this I needed an accurate bounding box for each point. When I try to calculate it (because the lengths are random) at the beginning using the bounds modifier I always get errors or it's just not working. Now I made a Custom Node to set the bounds to the calculated values and it's kind of accurate but there are some little discrepencies (5-30 cm on some houses, others are fine). Does anyone know why this could be the case?

[@SmartMoneyRyan]

any idea what resolution the image should be? ta make it clear and high res?

[@TommyLUTommyLingL]

hi great tutorials my man, but i am having issues with the texture data failed to initialize error, i have tried both compression method but the error still exists, i have no idea what is wrong wonder if u could help me, many thanks

[@MichaelRoyalty]

What's the base format of your texture? I've had luck with PNG and JPG. You can also try the "UI" texture compression option, another commenter had luck with that format.

[@TommyLUTommyLingL]

@@MichaelRoyalty hi, the UI texture group works! thanks for the info, keep up the great contents~

[@SmartMoneyRyan]

my submenu has nothing called PCG lol step 1 stuck, goign to be tough i guess lol
