  Hi Sebastian, Thank you for your response. I found the identifiers of the different VRay materials in the file c4d_symbol.h. Everything works.

  Hi @bentraje, I came across this problem some time ago. Have a look at: https://www.lasselauch.com/c4d-quicktip-shift-tags/ import c4d def main(): doc.StartUndo() sel = doc.GetActiveTags() for tag in sel: obj = tag.GetMain() taglist = obj.GetTags() for i, t in enumerate(taglist): if t in sel: index = i+1 if index == len(taglist): return #print """Tag: %s || Index: %s""" % (t.GetName(), i) doc.AddUndo(c4d.UNDOTYPE_CHANGE, obj) obj.InsertTag(t, taglist[index]) doc.EndUndo() c4d.EventAdd() if __name__=='__main__': main() This was essentially my approach, it’s not bulletproof but it works if you want to send multiple tags from one index to the next. Cheers, Lasse

  Hi @blastframe, Thanks for reporting the issue. Actually it's very similar to R21 GeUserArea in docked GeDialog behaves differently but as stated to the other topic, I don't have any news on that, I will bump development team again. So not the safest but as a workaround ignore the x,y, x2, y2 passed and draw with the data you defined in GetMinSize. Of course, this has the limitation that scroll groups are not anymore supported, but its the only workaround I see for the moment. Cheers, Maxime.

  Hi @bentraje can you share your code? I will say it really probably that you call ShowPopupDialog on any BFM_INPUT event and not to an enough specific one. Cheers, Maxime.

  hello, thanks @PluginStudent for the answer here :) if (obj != nullptr) // If I'm checking for nullptr could I just use if(obj) as in Python? The correct way is to check against nullptr, that's a c++11 standard. if (obj) could lead to false positive and bugs. String is not the same thing as maxon::String. String is the classic API while maxon::String is the Maxon API. You can read more about that in the manual about strings Error handling is super eady to use, we got every thing to do so, you should definitely use it. Check Our manual about Error Handling Last but not least you can probably use our Url class to handle file or filename. Give it a look Cheers, Manuel

  Manuel, thanks for taking the time and posting some links. Last night I was reading up on the Matrix and trying wrapping my head around it. I think I was stuck in the wrong area, I was trying to convert a baseObject to a pointObject to do the transformations.I would perfer not to have to open the axis window, but instead handle all this in a Python Function. I will look over the docs and samples to get a better idea of what I need to do. Thanks again for taking the time to respond to my post!

  @m_adam Thanks for the reply, Maxime! That fixed the issue with the slider, however the issue remains when the group is scrolled. I tried this in the Command method, but it didn't work: if id == self.ID_SCROLLGRP: self.ua.LayoutChanged() self.LayoutChanged(self.ID_SCROLLGRP) There doesn't seem to be any id or data passed to the Command method when the group is scrolled. I also tried listening for the BFM_SCROLLGROUP_SCROLLED message: def Message(self, msg, result): if msg.GetId() == c4d.BFM_SCROLLGROUP_SCROLLED: self.ua.LayoutChanged() self.LayoutChanged(self.ID_SCROLLGRP) return c4d.gui.GeDialog.Message(self, msg, result) This created a loop and froze Cinema 4D (I believe because self.LayoutChanged(self.ID_SCROLLGRP) may also be sending this Message?). Can you please help me understand how to redraw the Scrollgroup & GeUserArea on scroll? Thank you!

  @wen I was trying to do the same the past days. I could'nt figure out how to detect if Redshift IPR is enabled, but I found some relevant RS Ids. The 1038666 command opens the IPR window, but as far as I know there's no way to get the dialog instance to call IsOpen() The 1036752 CoreMessage is sent during IPR renders, but without any additional parameters (PAR1/PAR2). Not sure if there's something else we can extract from that message. What I ended up doing is adding a bool to my plugin to enable IPR features, but would be good to enable automatically.

  @fwilleke80 Yes or the RenderData but that means the data needs to be there before the token evaluation which is done before any scene execution render wise. Cheers, Maxime

  @r_gigante Thanks for this info. In two of my plugins I am already handling the TagData::Message to check for point and polygon changes (and other things as well). To my understanding, all this would be performed on the object remaining after the merge. What happens to the objects being merged "into" the remaining object, and especially the tags assigned to them. I am still wondering how to actually be able to merge the data from the other tags. Say you have 3 objects: cube. sphere, cylinder. Each has a custom tag assigned. To keep it simple let's say that the tag stores a user specified value. User has entered value 10 for the cube, 15 for the sphere, 12 for the cylinder. Now, when the 3 objects get merged (via connect or connect + delete or SendModelingCommand(MCOMMAND_JOIN ..., ...) the end result is the cube object receiving all the polygons and points, etc ... from all 3 objects. Internally the UVW tag is merged, etc ... The custom tag from the original cube remains as is, with value 10, and could react to i.e. MSG_POLYGONS_CHANGED in the TagData::Message. But ... how and where would I be able to handle the merging of values 15 and 12 into the custom tag ? Only when perform a SendModelingCommand(MCOMMAND_JOIN ... am I able to actively merge the values, as I know which objects will be merged, and thus can obtain the values from their tags before the joining is performed. With a connect or connect + delete, how to know about the other objects, and especially their custom tags? I don't expect this to be available inside a TagData::Message
