Triplanar Shader ( Feature Request )

[MarcusGT076]

Dear Khronos Team,

i would like to make an feature request. Is it possible that you can implement a triplanar shader for the PBR-Graph and Unlit ?
This would be awesome to have those shaders.

Cheers,
Marcus

Could you explain a bit more what you mean? I'm not aware of glTF having an extension for triplanar shading at the moment.

Hi hybridherbst,

so in shadergraph its possible to use a triplanar node for the textures. The object will be mapped from three sides and the textures are blend together. Shadergraph has it out of the box. I mean i can modify youre shadergraph to get this done, but it would be cool to have something in youre package already for that.

Cheers,
Marcus

Hi, I know what triplanar is :)

UnityGLTF is a plugin to bring glTF import/export support to Unity. What's not supported in glTF isn't really in scope for UnityGLTF, unfortunately.

One way to get this done is: proposing a glTF extension for triplanar shading, defining how it works, and then support for that extension could be added to UnityGLTF's shader graphs as well. Are you aware of the process for that? I'm not against it, but we usually can't spearhead such efforts solely from a "would be nice to have" perspective :)
