Vray-Animation-Quality..

[shikodesign2000]

Hi Friends,

 

I'm making now some interior vray walkthroughs, I'm using the famous tutorial of vray animation for http://www.spot3d.com

 

I calculated: Light Cache by "Flythrough" mode.

Irradiance map by "Multiframe incremental" mode.

 

Then use "from file" option and select the two maps: light cache&iradiance

map.

 

Then I make the final animation by using the 2 maps.

 

My question is: why the quality of the image is not high, I don't know? it's somehow low quality.

 

I'm using for the light cache: subdivisions=1000

sample size = 4

 

I don't know why the image is saturated. though I make the saturation=.5

I have had mixed results with those same tutorials myself. It does seem LC +IR is the best for interiors, however, I have found I generally get much better results when I use a sample size of 0.01 with the scale set to screen. I then turn down the saturation in the Indirect Illumination tab - I find 0.6 to 0.8 gives a good result.

In the tutorial, you can see that "world" mode is better than "screen" in interior walkthroughs, but for exterior flybys, screen is better.

Anyhow, I'll try your method, and get back again.

I tried your advice and I got better result, but do you know other settings or tips to make the quality more higher??

I think "subdivision" is one of these setings, meaning: higher values gives higer quality but increaing render time.

Cool - Im glad that helped even if just a little. Honestly I have found that most Vray settings are fairly generic.. I basically use the same settings for interiors every time. You might want to try a different anti-aliasing filter too - I like Catmull-Rom personaly.

 

You are right that subdivisions will usually increase render time, but that mostly comes into play when dealing with area shadows and glossy reflections.. You could try upping the samples in the LC and IR to get sharper GI, but sometimes the increase in quality isnt worth the render times it produces.

 

Looking at the tests you posted, I would say that some clever lighting would probably be the thing that would make the biggest difference at this point... Just as an observation, you have a good ammount of light in your scenes, but not many light sources (lamps, ceiling lights, windows, etc). Maybe have some sun coming thru the window, making nice hot-spots on the furniture.

Thanks for your advice, It will help me a lot, by the way; your site is very professional and I like it very much.

 

I'm with you about making some additional light source to make things interesting, but I think these light sources will increase render time also??

another question please: is there any way to reduce shadows??
