SSAO not working in IOS Safari

[Kesshi]

Somebody has an idea why SSAO is not working in Ipad? (tested with IOS 9.1)

I can't see any effect if i enable SSAO. ... only a huge performance drop but this was expected

On my desktop the same test works correctly.

 

The ssao example on babylonjs.com also doesn't work on Ipad.

Hi Kesshi,

 

Happy to see that you are a SSAO user !

 

These problems can happen if one of these features isn' supported on the device:

    - Floating point & render target textures (have to check if iPads support it but I think yes)

    - The SSAO shader: contains some features that are not necessary allowed/supported in all devices. Things such as a "for loop" with non-uniform flow controls.

 

For the performances, don't forget to compute SSAO in a lower resolution by passing a ratio object in the constructor like:

var ssao = new BABYLON.SSAORenderingPipeline("ssao", scene, { ssaoRatio: 0.25 /* or 0.5 */, combineRatio: 1.0 });

I'll try to find a moment later if I can update the shader and try to make it working everywhere, but not sure to success =S
