Hey all,
I’m trying to knock up a script to make use of the Effect ID function to use with the MultiMatteElement. All is going OK, but I cannot figure out why I am receiving an error when I test the script.
When I run the script I get –
–Unknown property: “material” in undefined.
and it highlights the line “if classof i.material == MultiMaterial do”
If I comment out either VrayMtl section, or the MultiMaterial section, then I no longer recieve this error.
This is a snippet of the code where I believe the error is happening. –
fn changechannel =
(
for i in selection do
if classof i.material == VrayMtl do
(
i.material.override_effect_id = on
i.material.effect_id = matidd
)
if classof i.material == MultiMaterial do
(
for ID = 1 to i.material.materialList.count do
i.material.materialList[ID].effect_id = matidd
i.material.materialList[ID].override_effect_id = on
)
)
Also on possibly an unrelated issue, when I try to test the MultiMaterial script, I recieve this error –
–Type error : array must be positive number, got: , got: undefined.
using this script on a multi sub material.
fn changechannel =
(
for i in selection do
--if classof i.material == VrayMtl do
--(
--i.material.override_effect_id = on
--i.material.effect_id = matidd
--)
if classof i.material == MultiMaterial do
(
--i.material.effect_id = matid
for ID = 1 to i.material.materialList.count do
i.material.materialList[ID].effect_id = matidd
i.material.materialList[ID].override_effect_id = on
)
)
Any help would be really appreciated, max script isn’t really my thing, but I try!
Cheers,
Dean
I think the problem with you first snippet is the lack of parentheses around the code in the for loop:
fn changechannel =
(
objs = getCurrentSelection()
for i in objs where isProperty i #material do
(
if classof i.material == VrayMtl do
(
i.material.override_effect_id = on
i.material.effect_id = matidd
)
if classof i.material == MultiMaterial do
(
for ID = 1 to i.material.materialList.count do
i.material.materialList[ID].effect_id = matidd
i.material.materialList[ID].override_effect_id = on
)
)
)
I’ve also added a check to test whether the object has the property material.
Here’s a way to find ALL VRay materials on selected objects. It should find those inside VRayBlend, VRayOverride, etc. not just multimaterial.
fn changechannel =
(
objs = getCurrentSelection()
for obj in objs do
(
vrmArr = getClassInstances vrayMtl target:obj
for vrm in vrmArr do
(
vrm.override_effect_id = on
vrm.effect_id = matidd
)
)
)
That’s amazing! Thanks a lot, that was going to be next on the task list, but you beat me to it! You’re definatley getting a mention in the script! It’s almost complete now, so will upload it to my site shortly and let you have a play!
Once again, thanks!!
Dean
Thanks.
I’ll definitely have a look when it’s finished. We use VRay mostly here.
Which company do you work for?
TSK group plc, it’s a design and build company.
Hello,
Me again! I have another querry, hopefully the last, before the script is ready.
I’m trying to select all objects where the effect id = 0
so far I have
selected_objects = $
for m in selected_objects do
(
vrmArr = getClassInstances vrayMtl target:obj
select (for vrm in vrmArr where vrm.effect_id ==0 collect vrm)
)
But when I run the script it says OK, but doesnt select the objects with ID = 0, any ideas?
EDIT: Also it would be great to collect where override_effect_id = off too.
Thanks,
Dean
Hi,
I not sure what you’re trying to do exactly. Scene objects themselves don’t have the property effect_id, they may have a material applied to them and the material might have the property effect_id. Do you want to select all objects that have a material applied that has effect_id set to 0?
Yes, I just want to select all objects that have vray materials applied, and that have an effect_id = 0
Thanks,
Dean
