Unreal Engine 5.3 - Sticky Triplanar Projection/Mapping

Unreal Engine 5.3 - Sticky Triplanar Projection/Mapping Tutorial
Topic: Triplanar Mapping In Unreal - Step By Step Tutorial
In this video we take a look at setting up Triplanar Mapping/Projection, the ability to project textures on to surfaces regardless of UVs in Top, Front and Side angles. This can be useful for Landscapes, Environment Pieces, or Masking Snow or Dirt and Grunge on top of UVs.
This video also explores how you can make these Projections stick for simple Translate or Movement of the objects as well.
For Object Based Triplanar Which Will Support Rotations Make The Following Modifications:
1. Connect Absolute World Position Node to a Transform Position Node (World Space To Local Space)
2. Connect the VertexNormalWS Node to a Transform Vector Node (World Space To Local Space).

I LOVE triplanar mapping, it was especially useful for a quick visualisation and decal splatting. This tutorial is incredibly valuable man thank you

[@mariansuran2426]

For simplification, you can use WorldAlignedTexture and WorldAlignedNormal nodes and also some other variants, which are already there since UE4, so no need for creating a custom triplanar mapping. Those nodes have input values for texture scaling and custom position and normal inputs so you can provide world space to local space transformed vectors as well, if you need your texture to stick on moving objects.

[@rzaman-gg6en]

So would this do the same thing but also follow the object's rotation? Because that's what I'd need.

[@-SL]

Absolutely brilliant. Finally a clear explanation of the nodes and what they do and why . A great tutorial! Keep it up! New fan here :)

[@AfterGlowCameras]

Amazing! I tried this on a landscape and it worked great, thanks so much

[@NeonFraction]

Thanks! This is very useful!

[@sergeykoshelev4566]

Many kudos to You. Looks like it's relatively cheap on resources too. I made it in to material function and added second conversion to local on object position.

[@redsnow936]

Maan thank you, your tutorials are the best! i love ur style, i love the efficeincy of ur workflow, this helps a lot! i am more then 4 years in 3d graphics and i really apreciate what u do, very usefull info as technical artist!

[@wottop4943]

Thank you for this!!!! This is very cool!!!

[@snookofficial7211]

Great video, well explained! Thanks

[@EddyNewhope]

Very helpful! Thanks much. For the sticky rotation to work properly, it looks like the Transform (WS to LS) needs to go after the scale multiply and before the BreakOutFloat3 rather than after the AbsoluteWP. I could be confused but that's how I got it to work on my end. Thanks again! Great stuff.

[@galiafvelikiy4615]

just WOW!!! Thanks a LOT!!!!!!

[@rzaman-gg6en]

Is there any way to make it match the object rotation as well? (Like the position compensation you did at the end) I've been looking everywhere for a solution to that.

[@ninadruzhkova4341]

you are superstar, thank you

[@ali.3d]

Amazing video as always! I've found when using the Sticky Rotation method - the blending seams of textures on curved surfaces are very stretched and much more apparent. Anyone have any idea why using the TransformPosition node causes this? Those stretch artifacts don't seem to appear on the regular triplanar setup.

[@RohanGulig]

what about Z axis ?? will it work for Z axis also ??

[@lasereyes5720]

at the 13 minute mark , coudn't we use 2 'Max' instead of 2 'add' to avoid the bleedover brightness ? Am to lazy to check.

[@fleity]

"Sticky" or static mapping by subtracting by object position is only helpful if you want to have scaling and rotation still act as if in world space. The easier way (which includes those too parameters into the projection) is to just use object space positions instead of world positions.

[@AlexandrosDemetriades67]

can you be more specific as I would like to lock both pos and rot at the same time? thx

[@fleity]

@@AlexandrosDemetriades67 instead of Absolute World Pos - Object Pos (Absolute) use the local space vertex position, not sure about the node name from the top of my head, something like object space, or local space position. It's important that this position is per vertex and not from the entire objects transform position

[@AlexandrosDemetriades67]

@@fleity Thank you

Thanks@@fleity

[@davidratajczak8408]

That's crazy to have to do all these steps for a simple triplanar texturing hahaha

[@williamlacrosse9389]

Do not consider UE5 like maya, 3dsmax, C4D, blender or something else. Create a tool and use it several times, share it, enhance it.

[@providencevfx_official]

@@williamlacrosse9389 Lol

[@AlexisSanchez-ss3il]

What about using this feature with an skeletal mesh using an animation? I've tried replacing the object position with the Pre-Skinned location trough a vertex interpolator but does not work. How I should approach this?

[@renderbucket]

For deforming meshes like characters and rigged assets UV coordinates and proper unwrapping are most suited for those situations.

[@quantumdeconstructor]

Nice! What about sticky rotation?

[@renderbucket]

Check the description. It has Instructions for object based triplanar with sticky rotation. 🙂

[@carlosrivadulla8903]

16:30 using a "transform position" node after AWP would fix the projection onto the obj as well?

[@renderbucket]

Yep! Exactly. Added the instructions for this in the description it just requires a couple modifications to the network to make it object based triplanar with sticky rotations.

[@AlexandrosDemetriades67]

but can you do both rotation and position at the same time? @@renderbucket
