Packed Automatic UVs Command in S22?
-
Hello, I'm struggling to figure out how to call the new Packed Automatic UV command from Python. I've found the BaseContainer where I can modify settings, but haven't figured out how to invoke the command.
Alternatively being able to invoke the Set UVW From Projection... command with the automatic packed option would be even more straightforward in this case. Is that possible?

I should mention that I can use
c4d.CallCommand(c4d.UV_SET_FROM_PROJECTION_CMD_ID)
but in that case I don't know how to set the options for the command via Python. -
Hi, I'm sorry I didn't get the time today to look more in detail, but you have CallUvCommand which accept one of the next flags (documentation is not yet correctly updated I will do next week):
- c4d.UVCOMMAND_PACK_UV
- c4d.UVCOMMAND_AUTOMATICUV
- c4d.UVCOMMAND_PACK_RASTERIZED
- c4d.UVCOMMAND_PACK_GEOMETRIC
- c4d.UVCOMMAND_PACK_BOUNDINGBOX
Next week I will provide examples about how to use them, in any case, you can find an example about CallUvCommand in the call_uv_command.py Example.
Cheers,
Maxime. -
@m_adam Thanks Maxime!
I'd found
UVCOMMAND_AUTOMATICUV
while perusing the depths of symbols.h yesterday but I couldn't find a way to make it work and I wasn't sure if it was what I needed... so I stopped looking into it. Your post renewed my enthusiasm and I went looking in the C++ SDK docs to find this:Which I believe will allow me to create my settings container for the command. I'll try this later today and let you know the results.
It would be nice to have the python documentation updated too

Well, it was a beautiful dream. The CallUVCommand to UVCOMMAND_AUTOMATICUV still fails when supplying a settings container based on the MDATA I found. In retrospect it does seem odd that these would be MDATA when the other UV command settings are not.
Looking forward to your examples. I'll keep stabbing blindly in the dark in the meantime.

Hi @wuzelwazel this command being part of the new command, that is supposed to work without bodypaint it needs to be called via SendModelingCommand.
Unfortunately for the moment, there is no symbols for this command ID.
But here you are:import c4d # Main function def main(): op = doc.GetActiveObject() settings = c4d.BaseContainer() settings[c4d.MDATA_AUTOMATICUV_TAGINDEX] = 0 settings[c4d.MDATA_AUTOMATICUV_FORCESEAMS] = False settings[c4d.MDATA_AUTOMATICUV_OVERLAPMIRRORED] = False settings[c4d.MDATA_AUTOMATICUV_OVERLAPIDENTICAL] = False settings[c4d.MDATA_AUTOMATICUV_SPACING] = 0.01 settings[c4d.MDATA_AUTOMATICUV_USENORMALS] = True settings[c4d.MDATA_AUTOMATICUV_SPACINGASPECT] = 1.0 res = c4d.utils.SendModelingCommand(command=1053624, list=[op], mode=c4d.MODELINGCOMMANDMODE_POLYGONSELECTION, bc=settings, doc=doc) c4d.EventAdd() # Execute main() if __name__=='__main__': main()

I never would've found the command id so thanks a ton for sharing that. Marking as solved.

This script did not work in S26.013(win),but work in R25. Is there any change between 26 and 25?
SDK seems not update UV mod
Please Help -
Hello @dunhou,
Thank you for reaching out to us. The script is working fine for me. Could you please describe more precisely what is not working for you?
@m_adam was a bit thin-lipped in his example, the example requires the user to select the object to unwrap. I have added a more verbose variant at the end of my posting.
Cheers,
FerdinandThe result:
The code:
"""Unwraps the active polygon object with MCOMMAND_AUTOMATICUV. """ import c4d # Main function def main(): """ """ # Bail when there is either no selection or the selection is not a polygon object. if not isinstance(op, c4d.PolygonObject): return c4d.gui.MessageDialog("Please select a polygon object to unwrap.") # Run MCOMMAND_AUTOMATICUV settings = c4d.BaseContainer() settings[c4d.MDATA_AUTOMATICUV_TAGINDEX] = 0 settings[c4d.MDATA_AUTOMATICUV_FORCESEAMS] = False settings[c4d.MDATA_AUTOMATICUV_OVERLAPMIRRORED] = False settings[c4d.MDATA_AUTOMATICUV_OVERLAPIDENTICAL] = False settings[c4d.MDATA_AUTOMATICUV_SPACING] = 0.01 settings[c4d.MDATA_AUTOMATICUV_USENORMALS] = True settings[c4d.MDATA_AUTOMATICUV_SPACINGASPECT] = 1.0 res = c4d.utils.SendModelingCommand(command=1053624, list=[op], mode=c4d.MODELINGCOMMANDMODE_POLYGONSELECTION, bc=settings, doc=doc) # Push an update even to Cinema 4D. c4d.EventAdd() # Execute main() if __name__=='__main__': main()

@ferdinand Thanks for your example,I do select a op in the OM.Last time I try it ,it did not work ,but this time it works well,I think last time I use S26 preset python text, and Optional is not import probly, anyway It's work well right now . Great thanks for you
