Help with artifacts and bluring

[jgray]

If someone could help me with these 2 issues, I would greatly appreciate it.

A. What could be causing the aliasing in this metal reflection/highlight?
B. Why do maps seen at a glancing angle appear smeared or blurred? And how can I correct this?

Settings... Vray 1.5

Adaptive QMC
Area Filter 1.5

Irradiance Map High 50/30

Light Cache 1500 Subdivs.
Sample Size .01
Scale:Screen

Color Mapping: Exponential 1,1,1

The maps problem is usually due to the buttugly pyramid filtering max applies by default. Just turn off Filtering in the bitmaps (set either the blur amount to 0.01 or select "none" for filtering)...or at least use not pyramid mode but area.

The highlight problem looks like reflections >1 with too low sampling. Try setting "clamp output" and "subpixel mapping" in the color mapping dialogue.

If not that, it could be the smoothing on those faces, you might try clearing the smoothing and see if it changes.

Thank you. Both recommendations worked perfectly. Send me your bill

lol watch what you say to those two...
Should they send you one, you'd better be ready to afford it

Some days I wish I could just throw money at the problems to make them go away. I'd be broke in a few days though

Interesting, should we just switch off max default filtering altogether for all maps? If so, through the maps individually or through the render dialog?

Well, yes and no. No filtering at all can lead to a lot of noise. So it stays a case by case decision i'm afraid. Esp with the additional memory requirements of Summed Area

yeah, i have no examples to show, but I've had some times when turning off the filtering caused bad/odd/ugly things to happen in the material...sometimes just lowering the amount to .2 or .5 helps.

When I know I can spare the rendertime, I turn off filtering for all of my maps and crank the AA right up to deal with it. I find it hard going back to filtered maps now, I can spot them a mile off...
