Iray preview not working on 1 char

Loony

Hi,

I am building a new Scenario and I have now the problem, that my iray preview dont wanna work if I wanna check my boy.

I had a idea what the problem could be... and yepp now I found it, its one decal.

So... why is the one decal making problems to give a irray preview?

I changed now one decal priority to 1, both hat it to 0, so maybe the engine get problems when 2 decals have the same priority?

It is still not 100% working :/

Here is a video:

(no longer)

(i didnt disabled the decal in the video), I got the idea with the decal after making the clip

But in attachment you see with/without decal on the slip (which is not even active, only the decal is active because its not a group and I have to disable it invidiual and forgot it).

 

The decals are from "Make me itsy bitsy".
