Hey,
I tried both sandard projection and triplanar, with a Transform 3D node, I have not success to move texture with translation. it stay in same place with differents values, I dont understand.
Using Octane 2020 RC2
Windows 10 - GTX 1060 6GB
Houdini DCC
Texture translation

I found the issue the Transform node need a Y rotation > 0 else not the texture translation no work. I setup to a very small rotation (0,001), and translation work.

With this rotation tip Iam unable to move the Z Translation by an attribute in houdini. I think its broken. When I move Z attribute translation, the texture move fine, except with a Attribut import. Its very tricky with octane (In arnold or redshift every things is supported 
)

Thanks for the test from your side, I think I have different configuration because I want a Box projection :

When rotation are to zero, the translation no work except if you set Y Rotation to 0,01

Hmm, what Octane version are you using? Here the translation works fine. In your scene, I can use the transform node, X and Z translation to move the texture over the plane.
Be aware that the translation is a float value with a 0.0 to 1.0 range to move the texture over the whole UV space. That means that a translation of 200 is the same as 0, or 1 or 10 ... try for example 200.2

Technically is it possible to move this translation data by any attribute ?
I tried with a color attribute called translation (vector) and connected to translation transform, it doesn't work.
v@translation = set(0.5,0,0);
I connected translation to albedo, I can see the data, but is work on a vector data in any node ???

Nope, sorry. I'm afraid that the transformation parameters can't be managed by attributes currently. The attributes only work for shading, but not to drive other parameters. I'll raise this feature request to the core devs.
