Shade MAP - Correct usage

[peterguthrie]

It seems to be working in the latest nightly on max 2013 (x64) but not max 2011 (x64)

[vlado]

I can see one of our programmers committed a few fixes for this today, so it will go into the next nightly build tomorrow. If you still have issues in 3ds Max 2011, can you get us more specific reproduction steps and a scene, if possible?

Best regards,
Vlado

no real hurry from my point of view but it might help someone else.

I get a crash even if I do this:

create teapot
create vrayphysicalcamera
create vraystereoscopichelper
set helper to 'render shade map'
specify an output path
hit render

Hi Vlado,

Is the Distributed Rendering implimentation for the shademap very hard to do??? Would it take much work???
DR is an essential part of life for a lot of people & we could use the shademap all the time if I we had that option, especially for HR renders of say 5000px or bigger....as you can't render those on just one machine if you have serious time constraints.
We could then be using DOF & Mblur on EVERYTHING......now that woud be a dream turned into reality.

Also are there any plans to put Shademap into the globals & make it less set-up intensive..? [this was already mentioned in another post]

Thanks for your time
Jamie

small bug in the path directory of the shademap

I noticed that Peter had a few problems with the Saving Shademaps...this may be of the same problem....
Just working on a animation project & using the shademap to produce DOF & Mblur. [By the way IMHO the SHADEMAP is by far one of the BEST things to appear in Vray lately. It's completely amazing to finally get super fast rendering of ray traced DOF & Mblur] The more I use it the more the more I wonder why you are not telling the world of this world-changeing addition to vray.

I did however notice that there seems to a small bug in the path directory of the shademap. It seems to create the shademaps perfectly each time although it sometimes/randomly fails to load up the same file when set to USE the shademap at render time.
-If I move the shade maps to a new folder & re-target the path & it loads it fine.
- If I then move the files back again to the original folder & re-target it loads OK ....now that's wierd?
This has happened 4-5 times & I tested it with the following
-only a single local machine
-through BackBurner using single machine
-DR Local
-DR through BackBurner.

Other than that the Shademap it just too awesome for words.. thanks so mach for that addition...now if only you could Create shademaps in DR ....

Thanks for your time
Jamie

I still can't get it to work without crashing even with the latest nightly build as of today.. max 2011 x64

[peterguthrie]

seems to be working OK for me now using max 2013 at least, just not at all on max 2011.




pretty useful speed up huh? (it took 18s to calc shademap)

[vlado]

Hmpf, ok - still looking into it.

Best regards,

Can you send us a scene, because everything here seems fine ?

Following this thread because I'm interested in using the Shademap for DOF effects more often... But as a side note (Don't wish to hijack the thread) I have to say well done to Vlado & everyone at chaosgroup for being on the forums all the time to help people out, it really is fantastic. If only Autodesk would do the same!

[peterguthrie]

Thanks to some hard work by the chaosgroup support team I'm now up and running and can test it properly. Just wondering what the minimum requirements are for creating the shademap? ie. how can I make the shademap creation stage as fast as possible?

[vasil.minkov]

You can create vraystereoscopic helper with suitable settings using the following script:

stereo=VRayStereoscopic()
stereo.enabled=true
stereo.eye_distance=0.0
stereo.specify_focus=false
stereo.focus_method=0       -- 0=None
stereo.interocular_method=0 -- 0=Shift both
stereo.view=1               -- 1=Left
stereo.adjust_resolution=false
stereo.shademap_mode=1      -- 0=Disabled, 1=Render shademap, 2=Use shademap
stereo.shademap_file="c:\MyFolder\MyFile.vrst"
stereo.position.x=100 -- move to the 
stereo.position.y=100 --  corner

[peterguthrie]

Thanks Vasil. I actually meant more along the lines of: Do we need to calculate GI when it is calculating the shademap? What paramaters can we tweak to speed up the shademap calculation?

[peterguthrie]

Just wanted to share some 'real world' results:

These are done with BF + LC, all settings the same for each render apart from turning on/off DOF, and setting the parameters for creating and then using the shademap.



So pretty much getting nice Vray DOF for free. yay!
