Higher settings does not = higher quality.

Hello everyone

 

I want to get some tips on how to improve this image.

I have changed a lot of settings around but i don't seem to get consistent quality. if you had to make a change to improve this render what would you do.

This was done with Rhino 5 + vary 1.5.

First I would just change the adaptive subdivision min/max rate to maybe 1-2 and (depending on your config) 3-5 (or more, but I dont think you need that high quality right now)

[Nic H]

what higher setting are you setting anyway?

need some screencaptures

[mariosantana]

sorry to take so long. These are the settings a chnage

this image was done with these settings

[Krisztian Gulyas]

-Irradiance Min/Max rate could be a bit lower. For min you don't need more than 1 or 2, for max 3-4 is enough.

The clr tresh should be around 0.2-0.3, dist thres 0.2 (0.1-0.3), Nrm thres 0.1.

-For LC subdivs I dont use more than 2000. I think it's not necessary, but it doesn't affect rendertime that much so you can set it higher if you want.

For LC sample size I use 0.005-0.01.

-Noise threshold is around 0.002-0.005 for high quality (I think 0.001 is too small).

 

Try with these settings and see if it's good enough for you and enjoy the faster render

 

EDIT: For Irradiance map I use -1 to 0 for min and 1 or (rarely) 2 for max (maybe 0 if min is -1). The above settings are nonsene about the irradiance map Min/Max rate, too high numbers.

...and try changing the camera and/or exposure settings so the room becomes brighter. It's a bit dark.

Thanks. i'll try these setting and post new images. i might have to move to 3ds max, there is so much more info/tuts.

Half answer, half question, but shouldn't IR Map settings be in the negative? A value of 0 means the IR Map has the same resolution as the final image, a -1 is half the resolution, -2 is a quarter and so on. Do the above settings mean the IR Map has a range of 8 (min 3) to 32 (max 5) times the image resolution? Seems excessive.

VRay Rino is based on the same VRay Max, Maya, Softimage SKetchup and so on, no need to purchase other software to get better renderings, Ben Norkin is right, the values you post are on the overkill side, The help information that come with VRay explain this in detail and with simple examples.

Form your first image, all that noise can be mostly for the sample of your light source (Shadows samples default 8) and your camera exposure to dark, also if you place some lighting inside of your room it will help the whole GI.

You can read hundred of tutorial regarding interior illumination with V Ray and apply exactly the same concepts to your scene.

Ben Norkin, you're right. I don't know why I wrote that. I use -1 to 0 for min and 1 or (rarely) 2 for max (or maybe 0 if min is -1).

Hey im back. i Update my settings and here they are

and a render made with these settings

It looks better but i still see a lot of noise and now i have jagged edges. I really don't know what to change.

Make the Irradiance HSph something like 150.

Make the Irradiance HSph something like 150.

 

Here is what i got with those settings

 

lots of noise on the cabinet.

[Ismael]

You have had noise on the cabinet from the 1st image you posted. Chances are the cabinet's material need adjusting.

While you're at it increase the Max Subdivisions of the DMC Sampler to 8 or higher.

[mariosantana]

thanks Ismael. i think increasing the dmc max sub helped. these are at 8 and 32

8

32

i dont know how no one mention it before you did.
