Vray Sky? - background problems

[pshupe68]

I was just viewing the tutorial again and nioticed that and was about to delete my post when you replied! Sorry - I will test again.

I guess "you", is it you in the video??, were using the standard camera when going between vraysun and direct to show the difference in intensity. Correct??

Regards Peter.

Yes, the drunken sailor speaking in the videos it's me

I used the standard camera to show unexposed values, but i could have used the Physcam with "exposure" unticked.

Wow - very cool thanks for the input.

My background is now white, not black as show in the tutorial?? I have the vraysky put in the environment slot and it seems to show white whether I have affect background or exposure under the camera settings checked or not??

Thanks.

Peter.

sorry, i don't quite get what you meant...

My background is not black but white for the vraysky?? You show putting an output map to increase the intensity of the Vraysky with a multiplier of 10 but I have to add an output map with a multiplier of 0.017 to get a value close to 1 , for blue, for the sky. I'm not sure why this is happening.

Also my value for the 255 or white plane was 31 so I used a vraycolor map with a rgb multiplier set to 0.255 as suggested and then I set my ISO to 50 to get the desired output, a value close to 1.

Could it have something to do with scale? Are these numbers scale indepependant?? I have my plane at 30m x 40m, with a photon emit radius of 50000mm to encompass my plane.

Thanks

Regards Peter.

You might have missed some setting here and there.
Make sure you watch it through before experimenting.
I recorded it live (never paused it), so if all other things are equal, you should get the same results by repeating the same operations

Yeah - Possibly - Is there anyway that you can supply that max file, with the gargoyle??

I am still having to add an output map at 0.025 or so to my Vraysky environment. Also there is loads of noise.

I'll take another look and post my scene settings again. Thanks for all the help.

Regards Peter.

Well - back to Maxwell - I guess!

Cheers Peter.

Lol man, a bit skippy
There's a whole thread on my tut, with many people getting what they wanted off it.
I didn't share a scene as it's really basic stuff i do in the tut.
What is it you want, a scene with colors at a quarter brightness and a camera exposed so that they look "white"?
It ain't a hard job in itself, by any means, but from a FLEXIBLE engine like vray it may require some attention (not much, tbh).
If maxwell ticks you off (instead of 25 sec renderings for the sameish results), it's entirely your choice.
No love loss, tbh

back to drawing board nothin to see here

Lele - I just needed to get something out, so I slipped back to Maxwell while I figured it out in Vray. I must have spent too much time in front of the monitor or something. I haven't really been back to it but will take a quick look again.

It is very frustrating when I know it can do what I am trying to do in a fraction of the time as Maxwell but I just couldn't spend anymore time on it without getting something done.

I agree it should be easy and I must be missing something that is staring me in the face. That is why I wanted to look at that Max file.

I covered most of the tutorials 3 parts at least 3x each and I am obviously still missing something. I will try on a project and see what happens. My projects are large file sizes and take a long time to render so adjusting settings at nauseum (sp?) is really tedious.

Cheers Peter.

It's here.
From your reply i thought you "abandoned" the ship entirely, so i didn't upload.
And i didn't upload it before as i was under some pressure from other stuff.
Also, read through the tutorial thread (mind the flames ), as people asked good questions and elaborated on it.
And there's a script lying around in it which helps with things (get version 1.1b. the first link won't work anymore as it had a bug).

In any case, welcome back aboard, dude

LOL - That's funny - Sorry! I was just frustrated I had to go back to the molassas approach for this one image I had to get out!

Thanks for all the help. As a lot of people, I find it increasingly difficult to find time to learn new things. My clients are happy with the status quo of my renders but I find them really bad in comparison to stuff I see here. I'm trying to learn in my spare time, which there is very little of.

Thanks again. I really appreciate all the help I am receiving. Especially from people so knowledgeable.

P.S. - Maxwell has it's place but, IMHO, will never come close to Vray for what is possible related to time to produce.

Cheers Peter.
