Triplanar Projection Improvements - Shader Graph Basics - Episode 29

In this shader tutorial, we add the finishing touches to our triplanar projection shader in Unreal 5 and Unity - including ensuring that the projection is flipped and rotated correctly, and that it doesn't invert on the backside of each projection. We also turn it into a material function in Unreal and a subgraph in Unity - so we can use it as a single node in future shaders.

Here are each of the previous videos in our triplanar series so far:

And here's the playlist for the whole series:

Godlike and still ther best library for me when it comes to shader functions. Thanks Ben!

Happy New Year Ben. Great series. I made a Project file where I replicate all your shaders. In combination with the Tharlevfx Channel I could create wonderfull stuff.

Hi Ben, Thanks for the video ! I was wondering, In Unreal what are the main advantages in using this method instead of the WorldAlignTexture/Normal nodes ? Also, is using triplanar projection is viable to use in a game project in terms of performances ?

Hello, would it be reasonable to use this method to break the tiling of a landscape coupled with rvt?

[mazfrans]

HI Ben, Thank you as always for the videos. Can we move into other shading model in depth content like Translucency, Hair, SSS etc too? Cheers :D

When flipping the orientations using the sign node, I found I also had to Transform the World Position to Local Position, otherwise some sides go back to being flipped in the wrong direction when moving the actor in the scene

[MonkokD]

Is there a way to keep it all in uv by dithering the blend between projections? A tried to accomplish it, but my results are not usable

Could you explain UE landscape triplana? I have tried this but I cannot figure out how to get it to work on a landscape

Hi. I'm using the unreal sea and I want to have foam on the shore part, the beach part. How is this done? Can you suggest sources from your videos or you tube?

[Twentyand]

Was testing this material on the default FPS project in Unreal and noticed theres an issue when applying the material to anything with a ramp. Any solutions for things that are at an angle?

[codyalday]

Same method to apply with a normalmap? Or is there extra math involved?

[Demnus]

Nice, but there is already premade nodes for that. But how about doing the same thing but with a single sampler? ^^
