Mental Ray Entialias

[Andrei2k]

I'm not really sure on how it works but i think that if its based on sampling maybe 8x8 sampling is the highest you can set it for.......:shrug:

[stunndman]

the recommended setting for high quality renderings is 1,3 - i think anything beyond that is pretty much useless - at least the documentation indicates so


Note that while this option offers simple control of rendering quality, it is recommended to control quality with the contrast option, which allows much finer control and deals more gracefully with high-contrast cases where the samples option can leave aliasing due to the hard cutoff.


a maximum sample rate of 8 means that one (1) pixel would be sampled a maximum of 65536 times - if this is correct than that sounds pretty insane

May be I´m using "force" instead of "mind", the reason why I´m trying to set maximum level at 8 is because I´m using DGS shader, and if I want blurry reflection to be smooth, I have to set up antialias in order to smooth the result. I would use "sampling overrides" in the atribute editor tab, but MR doesn´t seem to undertand it.
Is there a way to improve the antialiasing level for that shader only?

Thank´s in advance.

There is "max sampling" in the shader. Turn up that number. I think the highest it can go is 32.

Try lowering the contrast from default (0.100) to 0.050
This will increase the render time f**k loads

I suggest min/max samples 1 & 4

Cheers digger

Beaker, I think your answer must be right, but unfortunately, I can´t find that atribute.
In DGS material are Difusse, shiny, IOR and things like that, but no sampling in that shader, may be I´m searching for some hidden atribute?

Thank´s
