Rotating the input texture in triplanar node?

[hard scaffold]

Hi, is there a way to rotate an input texture for a Triplanar Node without having to just use a second texture? I was trying to see if I could use the same texture with two instances and rotate one of them to feed into the Triplanar Node so that I can lerp between the regular and rotated texture to get rid of visible texture tiling. However, the Triplanar Node only seems to take in a Texture file. Is there a way to do this in Shader Graph?

Triplanar projection is just math
There's an old but I think still functional pack with many nodes including triplanar projections
https://github.com/RemyUnity/sg-node-library/tree/master/Runtime/Nodes
Additionally with modern versions of the editor you can import shader graph samples from the package manager, they include some different triplanar projections too iirc
Also I think there's a sample that has the math of every SG node broken down into math nodes which also allows for customization and learning

I think I need to update my nodes pack 😅

the Triplanar node takes in a position to sample with

you just need to rotate the input position

note that this rotation will cause dramatic changes in the resulting texture depending on how far you are from the origin (in whatever coordinate space you're using)

you can use https://docs.unity3d.com/Packages/com.unity.shadergraph@6.9/manual/Rotate-About-Axis-Node.html for this

Yea you have to decide what point to rotate around, and relative to what

Thanks, I'll give this a look!
