V-Ray 3.5 Beta Feedback

[TutanMark]

Tried adaptive on a scene with lot of lights.

3.40.03: 52m33sec (probabilistic 16lights)
3.50.01: 53m (probabilistic 16lights)
3.50.01: 41m57sec (adaptive: 16lights)

Changing to adaptive shows lot of extra noise using the same number of lights (that maybe is not correct) ... and some kind of lighting changes that (for me ) is quite interesting.

NOTICE! Scene is not optimized and low quality gi and so on, just for testing purpose.

[Vizioen]

Both your images are the same.

[TutanMark]

Oops.. You're right. Now should be ok.

Quick test in preview quality

First one is with vray 3.40.03 and phoenixFD 3.00.01: 13m 51.1s
Second one is with V-Ray 3.55.01 : 10m 30s, but the GI on the scene is darker and noisier.


Third render: I increased a bit light intensity on scene in phoenixfd fire render settings to get a bit more light on the wall and render time was 11m 25s while still being darker on the wall.
I tried with adaptive light and render time and result were about the same.






Seems like the GI light attenuate faster in 3.55.

There was a bug in 3.4 that made matte objects receive a lot more GI than they should. Fix of it in 3.5 is probably related to this.

[jstrob]

Ok thanks for the info, it's on matte objects yes.

I keep getting the following error with a simple exterior scene using RT:

"error during initialization stage 9" (or something like that)

Any ideas?

[Teriander]

Where do I find documentation for 3.5? I have the beta installed but all the help sources I am finding are pointing to 3.4. Basically I want to test and learn how V-Ray works with the Vive via "Live VR Rendering".

Can someone point me in the right direction?

Thanks!

I added point 6

IPR
- When changing between buckets and progressive and pressing refresh, doesnt change. Idk why would someone wanna do this anyways, but might be useful to interactively change between those 2 modes as anything else
- Cant lock viewport in ipr. If i go on other viewports it starts rendering em.
- Color mapping changes do not affect ipr.
- Region doesnt work?
- Changing sampling/gi modes also doent work in ipr. Idk if it should, same as bucket thing.

RT GPU
- Low priority gpu should be on the fly on and off.
- Noise bump bug on vrayplane? (See image) Even if i get noise scale really low, doesnt respond proper.

RT CPU
- When i add noise at fog density rt stops working. And never opens again until i disable it.

ADV
- 0.99 reflection gives me wrong shadow reflections (see same image)

So far my feedback

Can you post that scene? It looks like something changed the default settings of your materials... do you use some "optimizer" script or something?

Is it safe for me to assume there isn't any documentation on 3.5? I don't mind continuing without it, just wanted to ask since it would speed up the process of finding everything new. A "yes" or "no" would suffice!

Thanks again!

UPDATE - Never mind, I figured out the Live VR issue I had. Thanks.

[vlado]

We do have a beta docs space which is in progress here:
https://docs.chaosgroup.com/display/VRAYMAXBETA

It does not contain information for the live VR rendering yet; I made a separate post about it here:

Hi short cirkuit,

I have too seen that same error in the past when using RT. I never did identify the cause and occasionally it comes back. I suspect it is something to do with another plug-in or script, and the use of a custom toolbar button.

If you like we can investigate by pm and compare a list of our used plug-ins/scripts?

Cheers,

John
