About generating Ambient Occlusion

[Wilzah]

Hey Zbrush Lovers.

A couple of questions…

I have been trying to generate a decent Ambient Occlusion map (UV layout version) for my model - but I find it’s taking forever - and the results are never as good as what I can get from TopoGun2 or XNormal. Any suggestions?

I’m using 4R7 - I have 16 GIG of RAM and a 6 core intel i7 5820 [i think] - Zbrush states in top left hand corner Zbrush 4R7 P3 (x64) - so it seems I’m not accidentally running 32 bit version, weirdly however - Zbrush installed into the (x86) program files - which to my knowledge is where 32 bit programs live … in the pixologic folder I can see both the 32 bit and 64 bit installers in same location - is this normal ?

I had the impression that being 64 bit meant Zbrush no longer was limited to only 4 GIG - and could be free to use much more…

Thanks in advance for any help

Will.

You can not run AO in Zbrush with high poly models, it will be so slow that will look Zbrush has crashed.
If you have subdivisions lower them until you have an acceptable speed.
You don’t have these limitation generating others as cavity etc. Because AO in general doesn’t need the detail of cavity it could be OK but I don’t think AO in Zbrush is brilliant, and not only because these motives.

I don’t think this is related to 32 or 64 bits.

Thanks Altea,

I’ll see what lower subdivs will do -

what I meant about 32 / 64 bit though - is why the .exe for both 32 and 64 bit versions are located in C:/Program Files (x86) - which, (at least to me) implies that its still a 32 bit program.

Surely the 64 bit version would run from C:/Program Files - without the (x86) extension on it. I thought all 64 bit program files ran from that folder … but hey, I’m probably thinking too much and should just get on and make more work hehe.
