That's exactly right

I don't really have the time for this at the moment, perhaps later

As far as I can tell, nothing has been added relating to this recently. I don't quite understand why UV coordinates can't be used for this purpose. The OP talks about "seams" caused by the use of UVs but I don't quite understand why that would be the case unless we're talking about multiple objects ...

you're welcome

ooh, interesting, perhaps it's a bug or limitation.

I discovered a new trick btw : Using a procedural noise as uv coordinates gives really nice results, and no seams of course :p
It also work swith vertex displacement

Out of curiosity : why do you need to import uvs from an ...

Can you show me the shader tree ? Perhaps you're using that in the wrong type of osl shader ? It also looks like you're using the components of a color input to use as uvw coordinates so my first try would be to import the uvs as point also

shader proj
(
color pos = color(0, 0, 0),
output point ...

I assume you're trying this on the old displacement node ? That one is quite limited and I'm pretty sure anything but a simple texture input won't work unfortunately.

Another thing to try, which will only work with the vertex displacement node, is setting your uv in an osl projection shader. ( u ...

Hi and thanks WoutTgh,
Would anyone share a file or show me how to use the OSL in houdini octane 2022 please?
or did Octane already come up with solution to use @rest for triplanar

Thank you!

Ello !
Off the top of my head: add an OSL shader ( for uv/mapping/projection ), paste the code, link ...

hey ! you're very welcome, glad you found it helpful :p

ooooh, that's the first I've heard of it, sound very interesting ! Do you have a link ? :p
