  Shadow problem

  Posted by Ben Hartley on January 28, 2013 at 1:24 pm

  Ok this is a bit of a fiddly problem. On my timeline I have An image within a 3d space with a Particle layer below and a ‘floor’ layer below that. The shadow of the image is not showing up because the particle layer between is not selected as 3D (which you want as it does it itself). In order to fix the shadow problem I must put the particle layer above the image layer in the timeline but I want the particles to appear behind the logo.

  Also now the shadow is flashing as my particle layer appears.

  If anyone can help it would be lovely.

  Thanks

  

  If it looks good, look at it.

  One approach is to leave the particle layer above all of the layers but use a copy of the logo layer as a matte for the particle layer, so the particles don’t appear over the logo.

  Thanks Todd but i will be moving the camera up so the matte would not block the particles accordingly in the 3D space.

  You can use the Obscuration Layers feature in Particular. This will allow the particles to appear behind the logo even if the particular layer is above the logo layer.

  See the tutorial:
