Hi @m_adam
Thank you for your reply. It works perfectly!

Hi there, I'm trying to mirror object via SendModelingCommand(c4d.MCOMMAND_MIRROR, ..)
But I cann't understand how to change a coordinate system.
According to the documentation this options is called MDATA_MIRROR_SYSTEM and it's int type.
Its description says Coordinate system. (See dialog.)
I believe it is the dialog:

It seems like 0 means Object, 1 - World, 2 - Screen.
I tried different values from 0 to 30, but it didn't take any effect.

The code I'm using:

settings = c4d.BaseContainer()
settings[c4d.MDATA_MIRROR_SYSTEM] = 0

res = utils.SendModelingCommand(c4d.MCOMMAND_MIRROR,
                          [obj],
                          c4d.MODELINGCOMMANDMODE_ALL,
                          settings,
                          doc)

I cannot change MDATA_MIRROR_PLANE either.
There is no additional information in the documentation.
Drag'n'drop for these fields doesn't work. It's strange, because it works perfectly for other tools.

I found this post (from 2011) https://plugincafe.maxon.net/topic/5497/5516_mirror-tool-bug
It seems that bug is still alive :(

Version: R20
Platform: Windows

Cheers

Hi everyone!

When C4D is in Polygon mode Grow selection can be done using SendModelingCommand e.g.

utils.SendModelingCommand(
        c4d.MCOMMAND_SELECTGROW,
        [op],
        c4d.MODELINGCOMMANDMODE_POLYGONSELECTION,
        c4d.BaseContainer(),
        doc
    )

After that, selection grows to neighbour polygons. Everithing is ok.
However, when active mode is UV Polygon then code above select neighbour polygons the same way how it was in previous case. Sometime it's ok, but not always.

The second way to grow selection is to use CallCommand

c4d.CallCommand(12558, 12558) # Grow Selection

In this case selection grows correctly in both modes.
I'll show an example. There is a simple sphere that separated by UVs in the middle. So it has 2 UV islands.

From 1 selected polygon (the first image) I want to get the result which is shown on the last image.
But I don't know how to get it without CallCommand
Sorry for mistakes. English is not my szcznek language

Thank you very much guys!
I think that plugin will be better solution then script in this case.
Cheers

Hi @mp5gosu, thank you for your feedback!
Yep, it has Undo problem. I assume, it's because the script uses CallCommand. And there are 2 places where I still don't understand how to avoid this :(

the selection should be restored after the process
Thank you for this remark. I'm gonna fix it asap.
Cheers.

EDIT: I've fixed the script. Now it restores the selection after the process.

I've wrote it by myself :)
Its presentation is here: https://plugincafe.maxon.net/topic/11336/script-harden-edges-of-all-uv-borders-break-phong-shading
May be it'll be useful for someone
Cheers

Hi, I'd like to present you a simple script.
It let you automatically select all UV borders and break their Phong shading, that might be useful for game modeling, especially with hardsurface props.
More info about hard edges - http://www.polycount.com/forum/showthread.php?t=107196

Unfortunately, the 'Texture View' window must be opened at least once for properly work :(
Just close 'Texture View' and continue work.

I've wrote a script which must make some calculations only once and then use these values until C4D is closed.
After C4D is opened again the script must recalculate values again, but only once.
It's not a plugin, but only python script.
Is it possible to realize?
Cheers

Hi, guys!
For Maya and 3ds max there are super useful scripts to harden all edges that are attached to UV borders. But I cannot find something like this for C4D. Does it exist?

Example MEL script:

I hope posted this question in right sub-forum.
Sorry for ma poor Englisch.

Hi @m_adam, thank you for your answer! I'll try command line.
Cheers
