  Hi @pim, In Python, SpecialEventAdd can only pass integer value, so the sender part can store the data into the document BaseContainer send the SpecialEventAdd/ Process this event read back the data from the active document BaseContainer. You can find valuable information on this topic https://plugincafe.maxon.net/topic/8219/10712_pluginmessage-and-pycobject-solved/5. Cheers, Maxime.

  Hi, I'm sorry you are having issues with Cinema 4D. You have ended up in MAXON's support forum for 3rd party developers. This is actually not a good place for user support requests. Instead I suggest to use the support form on our website. Cheers, Andreas

  Yes - dragging session only occurs in a 2D space - I thought so. Thanks.

  Thanks for the answer. I just started with a command plugin. New requirements emerged and yes, perhaps I now change over to a tool plugin.

  Hi Merkvilson, thanks for reaching out us. If the final intent is to simply get BaseBitmapinformation to be returned by your shader, rather than sampling a Xbitmap shader I suggest instead to simply query the color information by using BaseBitmap::GetPixel and eventually apply color space transformation. def Output(self, sh, cd) : x = int(cd.p.x * self.bitmap.GetBw()) y = int(cd.p.y * self.bitmap.GetBh()) col = self.bitmap.GetPixel(x, y) return c4d.Vector(float(col[0]/256.0), float(col[1]/256.0), float(col[2]/256.0)) Best, Riccardo

  Hi, I'm glad you found something working for you. I just want to mention, this way of using the deform cache directly will only work for very specific setups, for arbitrary object configurations you will most likely need to iterate through the cache. So, I think, it's worth to give those manuals another read. Also Maxime has posted some snippets in Getting a polygonal version of an animated mesh, which might be useful for you. Cheers, Andreas

  Well, I do have a loop but I just pasted the code that would, hopefully, perform the calculation. And I did tried the GetDeformCache approach, but my mistake was, in fact the cloning of the object. Thank you so much for the code, Adam.

  Thanks a lot Daniel for following up here. Glad to listen that the update actually fixed it, although even on 20.030 I had no better luck to reproduce. Best, Riccardo

  What the customer failed to mention was that the Team Render Client he used is on the same physical machine as his main Cinema 4D. Since both share the same plugins folder, the plugins were obviously installed manually for the main Cinema 4D, and thus also available for the local Team Render Client. Case closed.

  @a_block No need for apologies. I thought the bearded guy had something to do with it ... Hence the reason I posted the message again. Luckily, JIT before the easter bunny was to blame.

  Hello, the "checked" state does not have any functionality. It is just a visual marker for your user. Or to put it differently: you don't need to read if an element is "checked" since you yourself set this "checked" state in the first place when you create the menu with ShowPopupDialog(). best wishes, Sebastian
