[Closed] Anyone knows this MAXScript bug?

nope… try again.

Hmmm, very interesting. The invalidation has nothing to do with it. Regardless of the end result, this:

addModifier obj  (copy (Subdivide size:42))

is much faster than this:

addModifier obj  (Subdivide size:42)

care to tell us why?

I see.
Anyways, this one is faster than yours, but it is specific to the subdivide modifier

fn foo obj = 
(
	disableRefMsgs()
	local s = subdivide manualUpdate:0
	addModifier obj s
	enableRefMsgs()
	numPoints obj
	s.size = 42
	s.manualUpdate = 1
)

edit: actually my timing results are inconclusive.

for me the speed is the same. which makes sense.
also i don’t see the big difference with and without the disabling of ref-messages.

How are you benchmarking it? I get different results each time.

same issue with max2011 32bit , i try subdivideSpacewarpModifier() and the result is different
