 | | | Reference model question | Reference model question 2005-05-10 - By Guillaume Laforge
Back
I did exactly the same setup some times ago. Then I needed to put some
instances in a partition but it doesn't work, so I used the net view script
to convert instances in model ( 200 instances to convert...slow...and I lost
the instance advantage).
I found some "manipulation" pb with instances during this project. If you
need to edit the material on instance, it could be hard to find the original
object in the master model as render tree doesn't work with instances( a
drop down menu "a la Ptype" could be used...), however the getmaster script
help a bit. You must select an instance and run to select the original model
:
var oMaster = GetMaster(Selection(0))
SelectObj(oMaster)
(maybe it's in the GUI but I don't know where ? ).
Instance are nice for mentalray memory optimisation but could be difficult
to use.
