vray mat crash 3dsmax

Hello,

I am no more able to work on my on going scene. Max crash as soon as I try to open the material.
It works fine on the blank new scene, but not on this one.
I test with the original scene (never save with the nightly built), same result.
I switch to standard material editor, it finally came up after a long hangup (not responding) time (1minute).
I notice that I first need to open the material editor into a blank scene before opening my scene, otherwhise the material editor crash max.
Should I revert to old version instead of the nightly stable built?
Thanks

damn, I just started to have this problem ten minutes ago, all of a sudden. lost hours of time with it, now I’ll try your “fix.”

We will need a sample scene in order to find out what’s going on.
I remember that I had similar issue when all of my textures are loaded from a network location with a slow network speed - It seams that Max starts to load all the textures and until it reads them all it freezes and sometimes even crashes.
Which Vray/Max versions are you using ? And where are the texture located ?
