Dazed And Confused

Looking great!

Valerostudio,
Thank you, almost getting that 'Eureka' moment
-
Yes, looking much much better.
You might want to increase the hsph and samples (in LC) to get a cleaner render - but render times will increase so take it easy.David

How do folks feel about the "Universal Method"? I like using it on interiors. I find that I get extremely clean renders with this method.
-
What is the 'Universal Method'? is this something else I need to learn?
-
OK, I'll take the bait! What is the 'universal method'?
All I can see in the Vray presets is - 'test quality, low, medium, high and very high quality'

I have posted a series of 'internal' renders on the Chaos site, to compare the 'internal' render presets offered in Vray. The differences in quality are maybe not as great as you might expect, but the render times sure are.

Are saw those David, very interesting...especially the times taken...handy to know when you've got a client banging on your door

Found the Universal Method settings - gonna have to try it now......
The "universal" settings comprise a set of settings that we have found to work very well for still images in many situations. Please note that these settings are not optimal, in the sense that with enough tweaking, you can probably get similar quality with faster render times. The beauty of these settings though, is that they require almost no tweaking and you are guaranteed to get a good result in the end.
The advantages of these settings are:
very little parameters for controlling render quality vs speed (essentially, only the Noise threshold);
they work for a very large number of scenes;
they typically produce high-quality results.Of course, there is a disadvantage: the scene may render quite slow. With tweaking, you may get faster results.
These settings work, because the high AA subdivs essentially cause all the sampling to be performed by the image sampler. It will take as many samples per pixel as required to achieve the specified noise threshold. In many ways, this is similar to PPT (progressive path tracing), but is done on a per-bucket basis and the number of samples is adaptive for each pixel.
Setting the V-Ray renderer-
Set V-Ray as the current rendering engine (with the default V-Ray settings).
-
In the Image sampler rollout, switch the image sampler Type to Adaptive DMC. Set the Max. subdivs to 100 (one hundred). Leave the Min. subdivs to 1.
-
In the Indirect illumination rollout, Turn GI on, set the Primary GI engine to Brute force. Do not change the Subdivs. Set the Secondary GI engine to Light cache.
-
In the Light cache rollout, set the light cache Interpolation samples to 5.
-
In the Color mapping rollout, make sure that the Clamp output and Sub-pixel mapping options are off.
-
In the DMC sampler rollout, set the Adaptive amount parameter to 1.0. Typically you will also need to adjust the Noise threshold as the default may produce too much noise. A good value is, for example, 0.005.
-
You can also controll the noise directly from the Image sampler rollout, if you uncheck the Use DMC sample thresh. parameter, and adjust the Clr. thresh instead (e.g. to 0.005).

You don't say where these came from, but I googled them and I see they came from here:
http://help.chaosgroup.com/vray/help/150SP1/tutorials_unisettings.htm
I'll give them a try with my test scene and see what comes out!
(My guess is that these are superseded by the pre-sets - but we'll see!)
(mmmm - looks like a long job - will render overnight to test the time - but I can see now that this is not for me!)David

I gave the 'universal settings' a go, and they took 2hrs 45mins to render my test scene as compared to the new internal 'presets', which when on the highest setting (v.high) only took 26mins.
