@s_bach Hi Sebastian, How exactly can I reject the file selected by the user? This is what I tried, I can see the message dialog when the user selects an unexpected file, but the value is always set, independent if I return true, false, or unset the flags. Bool AnimationModifier::SetDParameter( GeListNode* node, const DescID& id, const GeData& t_data, DESCFLAGS_SET& flags ) { auto paramId = id[0].id; if ( paramId == anm_FilePathAttribute ) { auto suffix = t_data.GetFilename().GetSuffix().ToLower(); if ( suffix != "abc"_s ) { MessageDialog( "Select an Alembic file with extension .abc"_s ); //flags &= ~DESCFLAGS_SET_PARAM_SET; //return true; return false; } } return SUPER::SetDParameter( node, id, t_data, flags ); }

It is so weird that it worked in versions pre R20. Well, I will have to find a new solution, then.

AFAIK, frame all requires the document to be displayed in the editor. With some maths and iteration over potentially a lot of vertices in the document, building a scene bounding box, you might be able to come up with your own.

Hi from my test here is it's working nicely either reacting to C4DPL_BUILDMENU or by overriding GetSubContainer in a CommandData plugin. Could you please share with us some code that doesn't work and in which context exactly? Thanks a lot. Cheers, Maxime.

Hi @merkvilson, this feedback has been communicated to our development team. Cheers, Maxime.

Yes, that's appropriate. Thanks

This is really weird but after getting this error (and everything all being Ok), the way that I found to get rid of this error is to delete the xcodeproj, the props, the vcxproj and the vcxproj.filters files from the project folder, leaving just the projectdefinition.txt file there, and running the Project Tool again. Then, opening the newly created xcodeproj file, I no longer get this error and it compiles fine.
