About SP1

[Reaversword]

The first. All this feedback are product of use Vray for Maya 2011 linux 64, and like slave machine, Vray for Maya 2008 linux 32.

bug:
Distributed rendering FROM MAYA (not from standalone) keeps sending to the hosts the scene empty (or at least, in slave machines, will keep receiving the message: "Warning: Scene its empty"

bug:
Maya VFB remains to be unable to save the image in other format that not be .png, and besides, user still need write the ".png" after the name for take a success image saving. This with VFB of Standalone doesn't happens.


Really in Bulgaria the dawn happens at 4 at night?. In spain doesn't happens this (neither), but in Vray appears be as is. I don't know how much shadow mountains cast in the horizon, but I think the system its not all accurate we would expect yet.

I have seen you have fixed definitively the Vray for Maya 2008 bug that rendered different the bump/normal map. Good work!, Well done!.

And the glossy reflections now appears looking really really good. No more strange stretched dots. Good work again!.

I'll continue reporting finded problems in this thread.


....and please, remember publish SP1 documentation, its important for us.

Make sure to enter in the lattitude and longitude properly. Sun + Sky time in Vray for Maya matches up with SketchUp if you want to test objects.

I did it, but... try yourself over Bulgaria (42.450001 N, 23.200001 E) or Spain (38.080002 N, 1.520000 W)

By the way, we cannot choose North, South, East or West?. What are the predefined ones? North and East?

If We would have the documentation, this ridiculous things and stupid knowledge lagoons wont happens.

[snivlem]

Try downloading SketchUP (free) then compare the two. SketchUP is quite accurate.

By the way I tried Sofia @ 4 in the morning and it is still dark - what are your settings?

Lattitude: 42.667
Longitude: 23.300

2010/June/21 @ 4am GMT +2.00

Hi Sniviem, in first place, please, accept my apologizes for forget this issue.

The settings?. Lets go:

Lets start with a new scene, go to Render Settings and create Vray Sun & Vray Sky. Now go to GeoSun properties and unmark "manual position".

Latitude & Longitude are established directly in Bulgaria. 21/6/2010 its enough good for me. Now configure the hour in "4".

Now pick up the camera and add the Physical Camera parameters. Leave the Shutter Speed at 60 and the F-Stop to 2.8 (A configuration for Night, and very very probably still too much dark for take any shot at 4 am)

Render result in orange!


(And still without documentation we remains without know if Latitude&Longitude is North&West, or South&West, or North&East....). I think we should be able to choose it..


F*ck. I was created a 2.1Mb gif... impossible to upload. So, here some images

[snivlem]

No need to apologise.

Did you set the timezone to +2?

I tried your settings but get a blue render and the sun is where it should be, at night. See the attachment.



(In SketchUP those coordinates are NE) for other coordinates like SW do we enter in negative values?)

[Reaversword]

Im afraid you've mistaken my config. You've established Winter time (December, 6).

Try with my date, in Summer, (June, 21).


I've tested your configuration. For me appears blue too. The truth is that appears in Winter the system works fine now I tested it in your way. But Summers appears to need some retouch by side of ChaosGroup.

[snivlem]

Sorry that is true, my mistake! I have redone the settings and I'm getting an orange render too but I think the result is plausible.

According to Sketchup 7.1 with this date and longitude/latitude settings, the sun directly casts shadows at 4:55am in Sofia at this time of year. An early sunrise. I guess what we're seeing with the orange renders in Maya is just a sunrise effect in V-Ray.

I'm not sure what else. Maybe Vlado can confirm those early sunrises (if he gets up that early) :P

Well, then we need wait still a bit to know how is the dawn in Bulgaria.

In Spain, now in Summer, should dawn around 6 am, using the latitude/longitude system as you suggested (using negatives for South & West), and establishing GMT+1 in summer, appears the system start to behave correctly. At five o'clock there is a little dark yellow, and at six, dawn orange.

Sniviem, where are you from?. I mean, if you have some time, try to find the "dawn hour" for your county in summer in the vray sun & sky system, let's look if all happens more or less in correct hour..


And thanks for positive NE and negative SW suggestion. I'll add this to my particular mental documentation. Cool!.


P.D: Dawn at four o'clock!?. The world is getting crazy!.

I'm in Australia (GMT 10+), now in winter - it seems to behave correctly here. Before SP1 I think the system was way off but I'm sure Chaos Group now have it working right.

And thanks for positive NE and negative SW suggestion. I'll add this to my particular mental documentation. Cool!.

Not actually sure if this is correct. I hope Chaos write about this in documentation

[Reaversword]

Australia, winter now!. And I was telling you June was "Summer"... in my interior world, appears. I should leave the computer and travel a little bit more...

Thanks for explore this feature with me!.

Will develop Chaosgroup some day a "moon" simulator, with its four phases?. Reflecting with its albedo the sunlight in the correct angle?. Would be a point... any 3d software that had done it yet?. Mmmmm. Add Vray Sun, add Vray Sky... add Vray Moon... add fake stars!.
