Just to follow up, what Maxime suggested worked perfectly. No more cheating, basically just c4d.StopAllThreads() dialogThread.Start() dialogThread.Wait(True)

@r_gigante Thank you for your help. I used the maxon::String and it works fine.

@mp5gosu, that's true I didn't think about this possibility as well. Just for your information, an IcustomGui can only be done with C++ an implementation example can be found in customdata_customgui.cpp. Cheers, Maxime.

Thank you for the guidance. I'll dig into that info.

Hi @Ogers, a Dialog Layout can't be included within a Description Resource. With that's said, the only way to use GeDialog, GeUserArea into a Description Resource, is to create a CustomGUI (like the Gradient) then in your Description, you can include this CustomGUI. But CustomGui should not be used for a whole Layout, only part of it. An example of a iCustomGui implementation can be found in customdata_customgui.cpp. If you have any question, please let me know. Cheers, Maxime.

Hi @owen, thanks for following up. As @m_adam has already pointed out there's actually no difference in the values defininig a matrix representing a rotation on -30, -390, 330 or 690 on a certain axis. The lifesafer in this case is to use the already mentioned GetOptimalAngle which actually provides you with the HPB vector that would minimize the rotation given the previous HPB and the current HPB. For the sake of completeness let's assume that at frame 0 H = 0 whilst at frame 1 H = -5. Running the following code just returns the "expected" HPB vector def main(): # set the lastHPB to the previous frame value (in this case zero) lastHPB = c4d.Vector(0,0,0) # retrieve the current rotation order rotOrder = op.GetRotationOrder() # convert from matrix to HPB representation currentHPB = c4d.utils.MatrixToHPB(op.GetMg(), rotOrder) # get the optimal HPB vector optimalHPB = c4d.utils.GetOptimalAngle(lastHPB, currentHPB, rotOrder) print optimalHPB Now using this strategy and knowing the HPB of a clone at the previous frame, you are able to obtain a meaningful HPB representing of the matrix describing the rotation at the current frame of a certain clone (or object).

Hi @WickedP, actually all the drawing stuff is done in the main thread. In the next topic, you can find all the information about how the scene playback could be done in python https://developers.maxon.net/forum/topic/10292/13784_playpause-control-via-python/3. If you have any question please let me know, and be more specific about what you try to achieve. Cheers, Maxime.

Hello @m_adam, I wish you and all the members of the forum together with the staff Happy New Year. And thank you for your answer. It helped me a lot.

Congrats on the new forum! it is very informative About time

Hi Daniel, Thanks a lot, you are indeed right, SimpleMaterial.cpp has been fixed. Cheers, Maxime.

Seems I also forget to mention but please use About Tags and Tagging like so you can mark a specific version.

Hi, @m_adam Thank you for your kindness and the inspiring answer! It's a GREAT Christmas present for me! So sorry asking XPresso related questions in this forum. The problem I faced is a little bit complex than this: I need sample Effectors' total Output Strengths in the position from a Polygon Object's Points, and store the result into a Vertex Color Map attached for further use. This problem bothers me for months, and I didn't find any clue until your post. I have never think about using Python Node with global variable in XPresso Network can keep the data as I need and do the magic! From the bottom of my heart, I want to say THANK YOU. The answer you give not only solve this problem, but also inspire me re-thinking of ObjectList Node and Python Node, and how these nodes executed in an XPresso Network. Just let me THANK YOU AGAIN! Best wishes for you to have a wonderful holiday!

After a reboot, I'm able to reproduce it again... I will create a bug report and more testing after Season's Greetings & SDK Team Vacation. Anyway thanks a lot. Cheers, Maxime.

Hi again, It turns out that the issue was not related to Cinema 4d itself, but was caused by how I handled the connection to the 3rd party library. You can mark this as solved. Best regards /Filip

@s_bach Thank you so much for your help!

@m_adam wow! I did what you say,it works!! you are so cool!! thank you very much!!! yeah!!

I am still a C++ dinosaur, and particularly not experienced with the move operator. So thanks for pointing out the need for the manually written assignment operator. Together with the already implemented move constructor I had, I now more clearly see the point.

Hi arsen, I'm sorry but the bug is not fixed yet. I've pinged the group responsible for handling it and as soon as I received news about the fixing time frame, I'll report here. Best, Riccardo

Thanks for the confirmation SNHookClass still using the legacy String.

Hi @m_adam! Thank you for your response. I looked for a way to mark the post as a question while submitting, I didn't think to look at the submitted post again for that option. I'll remember next time. KillDocument and Exiting were never ment to run consecutively, they were just two things I wanted to try for different scenarios. I should have clarified that. StopAllThreads() unfortunately wasn't enough, but adding in a small message plugin to trigger the exit from the CoreMessage() did the trick. I'm now changing a global boolean for the CoreMessage() to look for. Is that what you had in mind? Thank you for your help, everything works now. I'll make sure and try and find the "mark as solved" button on my way out Edit: I can't actually mark your comment as the solution, only this one...
