Hi @Ogers, unfortunately, there is no direct way to do so. The only working solution is to retrieves the host of the shader (using BaseList2D.GetMain) Then iterates the description of this element and all its children to see where the shader is used. Cheers, Maxime.

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://developers.maxon.net/forum/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

Solved. There is TREEVIEW_OUTSIDE_DROP option.

@C4DS said in Send message to tooldata: PrepareData Your first answer works great! Thank you.

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

@s_bach Ok, Thanks.

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.

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

Hi, good we got you going It is not wrong per se to use multiple plugin directories. Actually Cinema 4D R20 was specifically designed to have multiple ones. You just need to make sure not to have duplicate plugins in these directories. Cheers, Andreas

Hi Sebastian! Turns out my issues are two seperate, but equally self inflicted problems Inserting and activating works as expected, I am blocking the update with some custom UI stuff so I will have to find a solution for that. Calling EventAdd() in the closeEvent of the UI doesn't do anything. Is there another way to force Cinema to update everything? Killing the document not only doesn't update, but actually crashes Cinema, because I am trying to kill the document from within a callback that is reacting to MSG_DOCUMENTINFO_TYPE_LOAD. I am doing some more involved environment management and sometimes I have to close a document after loading. I have a workaround that will have to do for now. In the callback I change the document path to a string I can then look for in EVMSG_CHANGE. When I detect my string there, I can then kill the document. It's not very elegant and if anyone has a better solution I would be very happy, but otherwise consider this problem solved

Please do not delete topics once they are resolved, this topic may help other people that have the same issue. Instead, use the Q&A functionality to mark a topic as solved. Cheers, Maxime.

Hello, the Source Processor only checks for coding style violations and creates auxiliary code. It cannot check for valid C++ syntax (because C++ is quite an complex language). Coming back to the issue of return values, only the compiler can check that at compile time. And, yes, unfortunately Visual Studio and Xcode behave differently. best wishes, Sebastian
