When converting all standard mats to vray ones trace reflection option is off. Is there a script to turn it on in all selected materials?
theMats=getclassinstances VRayMtl
for i in themats do i.option_traceReflection = on
Copy the two lines of script and paste them into the maxscript listener pink area.
Select them, and press shift+Enter (not the one on the keypad, the normal enter) to execute them.
This will turn the option on.
If you want to know what each option and spinner is, in the vray material, replace the second line with this line, and rerun.
showproperties theMats[1]
It will print out each option, so you’ll be able to quickly change them en masse.
Alternatively, turn the macrorecorder (Macrorecorder->Enable in the listener menus) and change the option in one material, to see printed out what you did.
