hi im having trouble writing a maxscript :banghead: using vray 3 and its new trace sets,
Looking at the vray 3 maxscript commands i have found:
vrayAddTraceSets <node>
vrayRemoveTraceSets <node>
vrayGetTraceSets <node>
http://docs.chaosgroup.com/display/VRAY3/MaxScript
What im trying to do is write two scripts but i dont really understand how to do this :
Script one
Select the 鈥渢arget object鈥? (object you want reflections/refractions to be excluded from) and add all scene objects into the exclude reflection/ refraction list.
The exclude reflection/ refraction sets can be found in the vray properties
Script two
Select all objects you want to be reflected/ refracted into the 鈥渢arget object鈥? Then select last the 鈥渢arget object鈥? Run this script and it would remove the selected objects from the exclude reflection refraction list. So this objects may reflect in the target object.
Thanks in advance
Ravi
Ok getting closer, i found this on chaos group forum, about creating trace sets with maxscript.
But cant seem to get this script to work? any ideas?
If you read my post above im after two scripts, i think its all in this script but i cant seem to execute it. :banghead:
Thanks in advance
