occlusion computation error

Unity Engine
1

I have just downloaded the evaluation version of Unity 3.2 Pro for Mac OS X.

I am just starting to evaluate the occlusion culling system.

But each time I try to bake the occlusion, i get the following error:

Error occurred in PVS computation. This is probably due to running out of memory or a problem with the graphics card. Try decreasing the near plane value or defining smaller PVS Volumes. Don’t lock the computer during PVS computation.

My first attempt was to rebuild the occlusion culling of the warehouse demo project. I got this error.

Then I tried to recreate the view and target areas but I obtained the same error.

Then I tried creating a very simple scene, basically a ground, a ceiling, four walls and a few cubes. But I am still getting this error.

What am I missing?

try lowering the resolution.
disable sleep mode stuff.
check if your object is marked as static.
on the importer generate lightmaps should be checked.
enable more VRAM, buy more RAM or another Graphics card?

Thanks a lot for your reply.

  • I am using the default settings of the iphone occlusion culling example. Shouldn’t this example work without changing anything?
  • The error occurs only 10 seconds after launching the calculation so the sleep mode is not involved in the problem
  • I shall verify that objects are marked as static but I imagine that this is the case in an occlusion culling example.
  • I shall verify that generate lightmaps is checked but what do lightmaps have to do with occlusion culling??
  • I am using a Mac Mini with a 2Ghz dual core intel CPU and 1.5Gb of Memory, the graphic card is an intel GMA 950 with 64Mb of memory. Will I have to buy a new Mac??
