Normal Maps + Triplanar

[FranklinTre]

Hello there,

Seems to be a well know issue but can't find an explanation.

I use Vray Gpu last version.

When I put the Normal Map coordinated by a triplanar to an EditablePoly the normal is doing nothing. Strangely it's working perfectly with a new plane or a mesh.
If I apply a UVW to the object (the EditablePoly), the normal map start to behavioring correctly.

So it seems to work only if there is a clear UV in the object... The problem does not occur in VrayCpu.

Why ? Is it a know issue ? Is there a propper solution, because applying UVW to all the object of the scene only for the normal map to work is totaly stupid since it's the purpose of the triplanar to deal with that...

Thanks !

Could you attach (or send) the scene so we can take a look?

Hello there, I have send you the file.

The problem of Normal Map occurs all the time. Though I attached this specific file cause it produce another weird issue with the Distance Texture (and maybe it's related to coordinates). When plugged directly to the material it works fine. Through a Composite Map where there is another Distance Texture plugged it's not working anymore. Its like there is a "loop" in the coordinates system and everything is broken. This bug is not happening on another file.

I am having the same issue here, triplanar works on cpu. it works on GPU with a newly created sphere, but on my custom geo it does nothing. no amount of xform resetting or mapping seems to change this

Mind if you attach/send the scene? I can't seem to reproduce the error with a custom object of mine.

Otherwise, I don't remember what happened to FranklinTre , maybe a colleague took and solved it, but forgot to write here.
