Triplanar bump mapping - weird issue

I’ve been trying to update my personal material library with triplanar nodes, and something i’ve noticed is that whenever i connect a triplanar node to a bump slot, it completely screws up the amount / type of bump effect.

This object is unwrapped, and i tried to have a similar scale with and without triplanar, and indeed something is wrong. With a bump amount of 10, the regular bitmap without triplanar works as expected. With triplanar, it’s like the effect is scaled by 1000%. For a similar effect i have to put the bump amount to something like 0.01 which is completely unusual. But even at that bump amount the bump effect is very weird too…

Others slots works normally, but in the bump slot i have this issue.

Any ideas?

Max 2015 SP3, Win 10, Vray 3.45.02 (26837)

Would it be possible to send us one of those scenes for investigation?
Thanks in advance.

I sent the scene to support@chaosgroup.com

Meanwhile you may use the latest official 3.40.02 versions, it looks like the issue doesn’t exist in it.
