  Trapcode Particular and Obscuration Layers

  Posted by Mamuka Kavtelishvili on April 14, 2015 at 2:59 pm

  I have a rendered 3D Scene which i imported from Cinema 4D in After effects also i’m using Trapcode Particular and want to twist particles around the planet *see the pic but i cant activate abscuration layer in particular, because obscuration layer must be 3D but i cant’t turn it 3D because of my camera which i imported from cinema. how can i solve this? thank you!

  Make the layer 3D and parent it to the camera. It won’t move.

  When i make it 3D it’s changing the position, because it was imported from cinema 4d.

  What exactly are you trying to use as an obscuration layer? Because I don’t think it works the way you’re thinking it does.

  You’ll need a circular masked 3d solid, with auto orient positioned at your planet’s position with the same radius as your planet.

  i’m trying to use my 3d rendered footage with alpha as an obscuration layer. i never had a problem with that but this time 3d camera is imported from 3d program with my rendered files.

  Then you don’t use it as a particular obscuration layer…just use the alpha to set the matte of the particular layer.

  Thats how it should be done, but it wont solve your problem…since you need 3d data to obscure…and not a 2d alpha information. You’re approaching this the wrong way

  I always use abscuration layer when i’m working with particular and animating camera inside after effects but this time i think cinema 4d generated kind of different parameters for the camera.

  anyways guys, thank you so much for your response and time 🙂
