quality AO bake not working

So i got a model i want to bake a 4k AO texture to, but for some reason it doesnt work.... When i try to bake a smaller pixel texture + less rays it works all fine but as soon as i try with 1024 rays + 4092 pixel texture it all is just messing up for me ...

for example, if i bake ao with 512 pixels and about 128 rays i get a nice texture image, with the right name, and it creates a new lambert for me with the AO linked, this lambert is connected to the object. All good. But once i try to do the same process with 4k pixels instead of 512 and about 1k rays i get to wait about 3 hours and all i get is a black image/part of texture baked/no texture at all/an odd image file, it doesnt create a new lambert with the ao assigned to it etc. its just messing with me. i dont know how to create this high definition AO that im looking for .... user added imageuser added imageuser added imageuser added image

Im doing Batch bake (mental ray) btw.

any suggestions?

thanks - skalman

What I have done in the past is create a file 1024x1024 with 256 ray with worked in about 10 minute then I increase size (4096) and blur a little in photoshop..............dave

Filter>Blur>Gaussian Blur.


Imagination is more important than knowledge.
