    Ray Traced 3D GPU Final Quality




      I have a problem with the Ray Traced 3D renderer.

      When in a scene, I have made a 3D object - which I have extruded. When I turn on the RayTraced renderer (from the classic) the object dissapears in the scene - Its there, but it wont be seen.

      I can see my object when i highlight it, or when i switch on fast draft - but not when in Final Quality mode (or any other preview mode than Fast Draft).

      The scene will also render when in CPU-mode, but it renderes extremely slow.


      So the problem is the object simply wont appear at all in the render. Theres no error message - its just not there.


      Fast Draft:



      Final Quality:




      From what I gather my system meets the requirements for real-time CUDA rendering. So why isnt this working?


      I'm on a Mac Pro, Mav OS X 10.6.8.

      Creative Cloud Trial.

      Adobe After Effects V.


      Fast Draft:     Available

      Texture Memory:     768,00 MB

      Ray-tracing:     GPU

      OpenGL Vendor:     ATI Technologies Inc.

      Device:     ATI Radeon HD 5770

      OpenGL Engine Version:     2.1 ATI-1.6.36

      Total Memory:     1,00 GB

      Shader Model:     -


      CUDA Driver Version:     4.2

      Devices:     2 (Quadro 4000, Quadro 4000)

      Current Usable Memory:     1,84 GB (at application launch)

      Am I using some setting wrong? Is this a known issue? Or are any of my graphics card not compatible with this mode?

          ATI cards are not supported and since this seems to be your primary card, it may throw off AE. Perhaps consider getting rid of it, if this is realyl that important to you...

            So that means After Effects cant bypass one graphic card, and utilise only the CUDA cores on the other cards?

              I tried removing the ATI card - now I've got only the 2 quadro cards installed in the mac.

              I also upgraded the system to Mac Os X 10.7.4.


              Still the problem persist. Any ideas?

                So you have  3D extruded  text and you are in the Ray Trace Mode.


                Have you created a light so the object can be seen? Kind of crucial step I didnt see addressed in your posting.

                  I have created a light yes.


                  The weird thing is that the composition works in Fast Draft-mode. The falloff from the light is displayed and everything. But once i switch to any other mode, for instance Adaptive Resolution or Final Quality - the object dissapears.

                  Though I can still see the whole scene and the outlines if I hoover the mouse over the object.
