SetSelectFilter by obj.name

[Light]

Hi,

How about freezing everything except the objects with the specified name? Frozen objects can also be made to look like they are not frozen, so I think this should do it.

Good idea, I'll have to test to see what kind of a hit it has on a large scene.

Likely better than any callback.

You can also use the isFrozen property on an array of objects, which would speed things up a little bit.

There's a callback mechanism available in maxscript which lets you add custom "Selection Filters" to the list in the main toolbar. Here's a simple example:
(

-- declare a global var for the callback function
global MySelectionFilterCallback

-- make sure any previous callback is removed
unregisterSelectFilterCallback MySelectionFilterCallback

-- the callback function (takes one argument containing the object to test)
-- a return value of true means the object may be selected
fn MySelectionFilterCallback obj =
(
-- returns true if the object's name begins with "Box"
matchPattern obj.name pattern:"Box*"

-- this callback function could virtually test against any object property.
-- the below for example would only allow objects with 100 or less faces to be selected

-- (getPolygonCount obj)[1] < 100
)

-- register the custom selection callback
registerSelectFilterCallback MySelectionFilterCallback "By Name"

-- activate the callback we've just created
local NumFilters = GetNumberSelectFilters()
for i = 1 to NumFilters do
(
if GetSelectFilterName i == "By Name" then
(
SetSelectFilter i
exit
)
)

)
I've been working on a script to add all sorts of custom filters some time ago, but never got around to finishing it. Maybe this is a good time to start working on it again :)

Yep did that :), made an array of objs frozen by the filter being enabled, so that when it was disabled only the array would be unfrozen.

Good simple solution, thanks light.

Thanks Martijn, I'm going to look into this tomorrow.

Thank you again Martijn, that was exactly what I was looking for.
