I found a reply here.

I know this is quite an old topic, @m_magalhaes @Jmelon it would compile if you put c4d.h at the end of all other STL includes

@mp5gosu
This sounds like the solution I was looking for 😅
Thanks a lot!

Ps, yes im a noob...

Thank you.
I will look into it and try it.

Thanks for the answer.
And yes, you are fully correct. Things should not be done in DrawMsg()

Hi sean, thanks for reaching out us.

The broken forward compatibility between R20 and R21 is reported on Changes in R21.
With regard to backward binary compatibility, it has never been possible to run a plugin built against a more recent API and load on a previous Cinema 4D executable as reported on Portability and Compatibility.

Best, R.

Yes your code could be optimized but we agree with you here this is not really the point, a R20 code is expected to have the same performance with R21 and here this is not the case.

And @C4DS I agree using GeIsMainThread() == false I would say partially fix the issue (sometimes it works as R20, sometimes not) We keep investigating it.

Cheers,
Maxime.

@s_bach said in Plugin not found after switching layout:

The ID used with GeDialog::Open() and RestoreLayout() is typically the plugin ID of the CommandData plugin.

See e.g. activeobject.cpp

Thanks.
It had to be something so simple I kept missing when reviewing the code.

Thanks for the explanation. Works as expected.

@m_adam
Hi Maxime, thank you for the quick reply and insight into this. I look forward to trying this.

Correct, and I would say a CommandData id.

@r_gigante

Thanks for the response. Works as expected.

@m_magalhaes

Thanks for the confirmation.

@m_adam Thank you, Maxime, for going to this effort.

Hello,

please open a new thread for that question, we will probably need your code. You can send it to us using our email [email protected]

hello,

To retrieve the active object you have to iteration trough the hierarchy. (even GetActiveObject)
In Python, GetActiveObjects is calling a c++ function so with lots of object it will be faster than iterating the hierarchy with python functions.
We don't know what the limit is. To mesure that you have to make a bunch of tests with different scenarios and get the mean.

Cheers,
Manuel

@r_gigante Thank you, Riccardo! I don't know how I missed that in the documentation, but it is what I needed. 😄

Thanks! So will find some workaround.

Hi,

if I am not overlooking something here, the function recurse_hierarchy is neither recursive nor will it retrieve the layers for all objects in the scene. It will retrieve the layers for all siblings of the passed node, that were born after that node.

You probably made a mistake copying your code or misunderstood what is meant by recursive.

zipit

@r_gigante

Gotcha. Thanks for the warning.
