I am having a code like this:
m=$.mesh
setnumverts m (2*m.numverts)
for v in m.verts do ...
When triing to execute this code geting this mesage:
I tried to insert “update m” befor the for loop, but it was of no use.
When you create with .mesh it’s only a mesh in memory. It can be more stable to create a node and work on that. Note that I delete the node when done, but you can do whatever you like.
(
m = mesh mesh:$.mesh
setnumverts m (2*m.numverts)
for v in m.verts do
(print v)
delete m
)But I would like to avoid creating node since it have to be manually deleted. I mean when this code is executed many times it´s a performance isue and since I am using old PC with an old max version, performance play a role. I still have acces to the most trimesh values after changing the number of verts exept that verts property.
What exactly do you need to do?
Can you show a complete useful and working code as well as a simple test scene?
Just then someone here might be able to give you a useful tip.
After reading your answer in the other thread it is posibly beter to change
for v in m.verts do ...
to :
for i=1 to m.numverts do
(
v=getvert m i
...
)OK, after I have changed
for v in m.verts do ...
to :
for i=1 to m.numverts do
(
v=getvert m i
...
)
everithing worcks fine.
