Raytrace engine setup probelm

Good day mga master ask ko po how to fixed this problem, when i render with vray i got these problem RAYTRACED ENGINE SET UP PROGRESS BAR and the quickly followed by UNHANDLEd EXCEPTION ERROR DIALOG BOX and then in 3dmax/vray crashes. Pero pag ovewride ko po materials nagrerender naman siya. I have encountered this before and medyo masakit sa ulo. Panu kaya ito mga master my alam ba kayo na solusyon dito? thanks in advance.( still on the net to this baka my mahnap na solusyon)

use 64bit o.s.

- Switch back your renderer to scanline -->>go to raytracer -->>under Raytracer Global ParamEters, untick Show Messages, then switCh back again your render engine to Vray.

try this one... right click sa viewport mo sa max.. then click on vray scene converter.. it will force all non vray setups and non vray materials to become a vray material...

Thanks po mga master solve na po problem ko. It seems that there is a raytrace map applied on 1 materials of my scene. I simply convert that materials to vray mat and voila okey na po.. Thank for your suggestion mga master.. more power po
