yes, that’s crashing… As you might find already out, alternatively avoid the VrayNormalMap.

A little suggestion: check out Tyflow if possible and you should not know already. In Beta already a very stable and very good tool, AUTODESK can only dream of.
It´s even also faster and technically in all concerns way more progressive than good OLD Pflow.

You can also simulate perfect grinding with Coffebeans… =)

Hellom caypiranha Thank you for your reply.

I have already found a bug report.

This may be a problem on the Autodesk (PFlow) side.

Tyflow. Yes it is the best choice. I love Tyflow myself.

I’m a Chaos reseller in Japan and this issue was reported by my customer.
Therefore, it is unknown whether the customer will use Tyflow.

hello flat,

ah, I get the picture.
Thought a little similar on that, by visiting your given link and gathering - apparently only purely visual information… =) A good way for gathering bugs.

@flat
FYI. The issue is already under developer investigation.
