Hello,
I am not sure if this has been asked before or it’s possible with magmaflow?
In a recent project, I wanted to use multiple object in PRT Loader for particles culling, some objects supposed to be input as invert culling node and some as normal culling node.
But I can choose only one selection set in culling mode. Is it possible to add multiple selection set and set them different for culling particles? (or maybe multiple objects list?)
Thanks,
Regards,

The PRT Loader supports only one selection set which can contain any number of objects, but all objects are used either as inside or outside test. That being said, since the test is based on normal direction, it is possible to add a Normal > Flip Normals modifier to some of the meshes to invert their inside-outside test!
Magma can surely do that too by using multiple meshes (you need one InputGeometry node for each mesh) and combining the results of multople InVolume nodes to a single logical value to pass to the Selection channel.
Thank you Bobo! I will check with “Normals” and also try out magmaflow.
