Vray 3.0 Setting, viropt Heellpp
-
Hello there! I'm currently on SU 2017 & Vray 3.0 and have been working on the setting for the past two days and the result is still..
Can anyone share me any visopt or viropt vray setting for interior render vray 3.0 please?
Your help is very much appreciated!!! -
Settings highly depends on the scene. If you can share your result with setting screenshots, we can help and give some advice.

Hi. Thanks. Giving myself more time to try.
the rushy ones i had them done with loading su2015, vray 2 viropt settings, still presentable but the render is super slow. Will come back with the printscreen soon. -
Hi there.
attached pictures below are the settings for vray3 (which i had not get the hang of it yet)

Your scene is dark, because sunlight doesn't seem to be coming through from your window. Check Solar North plugin and position your sun direction properly (And tweak your daytime inside SU). Also make sure that window itself or glass material doesn't block sunlight (Hide windows and test render).
Brute Force is slower but more accurate. Irradience Map + Light Cache combination is best in most case (a lot faster and result doesn't change much). I don't know why this give you bug splat, i suggest asking in both official forums of SketchUp and ChaosGroup (Vray) to get a proper response.
Your Light Cache sample size looks unnecessarily low, change it to 0.03 (maybe this fix your crash). See this official manual for more info: https://docs.chaosgroup.com/display/VRAYSKETCHUP/Light+Cache+Settings (See left section for other settings or search)
Also your Noise Limit under Raytrace looks too low, change it to 0.05 . Let Denoiser handle noise problems, it's a lot faster!

Hi Filibis, currently testing out the settings. Thanks for the fast reply! Will come back for some further details.

Hi there. Thanks for the comments last round, the renders have been running well. There is only one thing which is still bothering is that it takes hours to finish a render. Below attached the print screen of my settings. Please comment!

Oh, and I'd definitely turn ambient occlusion OFF. If you think you really need AO, try adding it through a render element. ExtraTex render element with Vray Dirt as the texture. Then add the pass in photoshop set to multiply and adjust opacity. Gives you more control and doesnt add heaps of render time. The actual ambient occlusion setting you are using adds render time and on top of that adds a lot of noise....that you have to then try to turn up quality setting to get rid of...which makes your renders even longer. A viscous cycle.... (long story short: turn off ambient occlusion.)

Hey Angevin,
Something seems wrong, a 1000px render shouldnt be taking hours to finish. I run my test renders that size and they generally take from 30 seconds to 5 minutes to complete...(this is relative to scene and your pc, of course.) Your settings seem cranked up pretty high...in some places...not very balanced either.
I don't think there is any reason to ever have a minimum of 2 subdivs if you're using an adaptive sampler. And 24 subdivs is really high....and .05 is really low (not very balanced). Denoiser can steal a lot of detail, so it isnt a good idea to make it do too much work...specially if you're using irradiance map as you primary bounce. I find Light Cache of 1500 tends to be low for our interior scenes, although .05 sample size is a pretty high one. Usually don't go over -1 for Irr max rate...Anyway, its a good idea to start with the built in quality presets, (the 'quality' slider under 'Renderer') Medium is a good start, try high if you think it needs it. Then only change one setting at a time and render a small region with the region render window to see if it helps quality without effecting time too adversely. If you're having crashes and long render times, good to try copying and pasting in place the whole scene into a new SU file. Sometimes there is just something corrupted in the file and this is the only/easiest fix. Since Vray 3.4, I'd say this happens to 1 out of every 4 files!!...yeah 3.4 is still pretty buggy...
If you want me to take a look, you can PM me with link to download file and I'll see how it runs on our machines...I'll even hone in some fast quality settings for you. Could give you a good place to start with your settings in the future.
Cheers,
GD
