Screen Space Ambient Occlusion Crashing

[markarjun]

Hi all,

 

I've been using screen space ambient occlusion and it keeps crashing on me. I have an Nvidia gt540m graphics card on my toshiba core i7 laptop. I try to use just the cpu to render the screen space ambient occlusion but it still fails. Any ideas or setting I might be able to use? Does anyone else have this issue?I have a deadline coming up, so any help would be greatly appreciated.

 

Thanks

 

Mark

First, is it sure that the SSAO is the problem? If you turn SSAO OFF, the scene will render?

 

I'm not sure about CPU-only SSAO. How are you turning that on?

Hi Robcat! Yes it seems to crash when I turn the SSAO on, and renders fine when I don't, which is frustrating because it looks great when it does work. By right clicking on start-up i can choose whether i want the nvidia or the on-board graphics card, if i choose the latter it will use the CPU based SSAO when rendering, this is slightly more stable but still crashes.

If you can post a PRJ that crashes or want to send it to me privately in a PM i'll take a look at it.

 

IF SSAO is the problem perhaps a work around for now would be to drop back to v16 and use the FakeAOGPU plugin which is free for VGA resolution.

How many frames do you have to render?
