Issues w/ CoronaAO upstream of Mapping Randomizer/TriPlanar

[John.McWaters]

Before Corona 10, I seemed to be able to have CoronaAO components upstream or downstream of MappingRandomizers and Triplanars, but in 10, CoronaAO's are not behaving correctly for me when they are upstream. Is this expected behavior?

For example, this is the result when I have the following material setup...Checker map>CoronaAO (w/ a red occluded color)>Mapping Randomizer>CoronaTriplanar. Is the Mapping Randomizer acting on the upstream Corona AO component? If so, I don't think that was the case in previous versions.

edit: after a little more research, it looks like it behaves correctly in the CoronaAO is placed between the Mapping Randomizer and CoronaTriplanar...you just can't put it upstream of both.

Hi,

I can confirm that using CoronaAO before CoronaMappingRandomizer gives unexpected results.
But that is not the expected setup, the CoronaAO should be used after MappingRandomizer (and/or Triplanar).

Because you want to randomize and scale/map the texture, and then add CoronaAO to it, which is geometry based and not texture related.

Setting up CoronaAO after MappingRandomizer should give the expected results.
Or you can use it the other way around to get some "interesting" results, optionally with another CoronaAO after mapping randomizer for correct AO.

Hi,

This should be fixed in v11. You can grab the latest daily build here: https://forum.corona-renderer.com/index.php?topic=40442.0
