Create a Puddle Decal Generator for Unreal Engine 4 with Substance Designer

In this tutorial we create a puddle texture in Substance Designer and export the maps into Unreal Engine 4 so that we can apply them as a decal. We talk about what decals are, why they are useful, and how to set them up in UE4. Once you create the generator, change the random seed of either the full graph or the different grunge maps to create an unlimited number of puddle textures that you can stamp on your environments.

5:03 All grunge maps and noise generators in designer always tile by default. You wouldn't be able to use them very well to make tileables if they didn't. Also, a thing to note about decals, if you look at 15:26 you can see the decal is projecting on the wall. If you don't want that to happen, as quite often it looks strange and isn't what you're going for, you can click on the mesh, go to its details on the right, and type in "decal". You then uncheck the "Receives Decals" button which makes it so that specific mesh won't let any decals get projected on it Thanks for the tutorial :)

Another great video thanks!

[@JeremySeiner]

Thanks!

[@00walid]

Beautiful, and for better performance while compiling, you could pack all 3 maps into one map and call it NRO. One decal with one map, easy to recognize if you have dozens of it in your project...

[@JeremySeiner]

Absolutely! Great idea!

[@3DWithLairdWT]

This was a great tutorial. Out of curiosity, how performant are translucent decals? Generally I've been taught to avoid translucent materials unless absolutely necessary.

[@JeremySeiner]

Glad you liked it! Personally I haven’t tested the two so I don’t have the answer. But if anyone else here does they can chime in.

[@gerardorojas3856]

thanks for the tutorial, is it possible to animate this decals? i would like to replicate the silent hill corroed walls effects.

[@JeremySeiner]

Animation is possible but it’s not very straightforward on how to achieve it. I would say do a search for the “time” variable in substance designer to get an idea of how to approach it. You could also keyframe an exposed parameter from an SBSAR file in unreal that is going through the substance plug-in.

[@gerardorojas3856]

@@JeremySeiner thanks for ur anwer!

[@arespin35]

Thanx more for usefull videos again. Create patreon account.

[@JeremySeiner]

Thanks! I’ve been thinking about Patreon. Just want to make sure I do it right before make one. Happy to hear you’re interested! 😊

[@cgmax7]

why not use SBSAR File ?

[@JeremySeiner]

I suppose that’s possible as well ☺️

[@mjaada]

Could this work for Unity?

[@JeremySeiner]

Yes I believe so as long as they are set up for transparency.
