Is it possible to delete a modifier though registerTimeCallback?

[Anonymous]

Hey there, just like the title asks, is possible to delete a modifier from the stack each time the timeline position is changed using a function called with registerTimeCallback?  I am using the script below to copy uvs from one object to another and this creates a new UVW Mapping Paste modifier each frame.  I would like to be able to clear the previous instances of the modifier at the beginning of each frame as part of the function which does the uv channel operations.  I am quite new to Maxscript, the standard deleteModifer command does not seem to be able touch the stack from within the function called by the registerTimeCallback event.

Here is the script so far:

fn UVUpdate = (
deleteModifier $ROADANIM 1 --<--Does Nothing
ChannelInfo.CopyChannel $ROADFREEZE 3 1
ChannelInfo.PasteChannel $ROADANIM 3 1
)
registerTimeCallback UVUpdate

Thanks in advance peeps! 

EDIT: I didn't realize that 3Ds does not keep an eye on changes made to a script at save time when that script is actively running in the app, had to hit ctrl+e to get it to update... -_-

Hi yamanashg,

I saw you edited your post, does it mean you found the issue ?

Just in case, it does work, it is that you cannot 'see' it as you re-add one just at the end.

As a test, just do not do the "ChannelInfo.PasteChannel" and you'll see that your modifier gets deleted.

Cheers!

Hello @Anonymous,

Thanks for updating the thread!  I'm going to move the thread to the Programming forum because I think it will be easier to find there for future users.  Thanks very much!
