Hi, i have a slot where the user can drag materials which are used by my plugin. however, when the user hits delete unused materials the materials which are used in the plugin are deleted as well...

maybe someone has a solution? in the docs i found MatAssignData and MatAssignData which sounds like what i am after, but how do i use it?

thanks for any help, cheers,
ello

Hi,

Your plugin should respond to MSG_MULTI_MARKMATERIALS and mark (mat->SetBit(BIT_MATMARK)) your linked material.
See the code in this post: https://developers.maxon.net/forum/topic/5051/4975_question&PID=20321#20321
You can also refer to the class MarkMaterials documentation's page.
