I’m trying to render a pic 12000*9600 pixels and i get an
“unknown renderer error(initializing renderer)” when i send it through backburner
what do i have to do in order to render it at that size?
btw
this is an old project in we swiched back to vray 1.09.03.n on max 5.1
thx
Gili
First, what in the world are you going to do with an image that size?? :shock:
Are you using stripes in backburner? That should solve it.
Hi
my customers want to print it on 100*150 cm on a printer that does print 200 dpi.
I can’t use stripes because this project is on max 5.1
Only other thing that comes to mind is doing it manually. Try render regions and select a few (4? 9?) overlapping areas. Just make sure to render to TGA or something with alpha, and stitch them back up in PS.
FWIW, I used to do plots that size to 200 or 300dpi until I ran an experiment one day and plotted it 100dpi. The difference was barely noticable. Now I never do anything higher than 100dpi if the sheet is bigger than 12"x18" or so.
there´s a freeware plugin called bigrender from Tomas Cayuela Caudevilla that´s splitting the image in definable buckets, renders these and put´s it together…it´s working with vray

What is the maximum size that max render?
I remember some posts about much larger renders…
32768 pixel if you have enough memory…but use bigrender…you can render up to 99999 pixel and poster the world…

Hi thomes
thanks for the script
Its rendering now (5 of 25)
Hope it will turn out good , I’ll keep you posted
Do you know which order does it render or is it a puzzle work in ps?
hi gilicom
i hope you did a test render… i imagine that there is a checkbutton to save every bucket…or the whole frame put together…
good luck 
hope you took the right one
thomes
yes i did a test render ,it does save them as bmp sequence
:lol:
still renderenig…
ouch, why do you use bmp?
will be around 300mb in size
i’d stick to png/tif for something that large (esp. the lossless compression of png is quite effective on cg images)
hi gilicom
hope you precalculated the lightsolution first. :?
maybe you get problems with the edges of the buckets…every bucket calculates its own solution…
it´s like with backburner, if you stripe a picture without precalculated illuminationmap…every pc calculates its own gi-solution and you get a possible hard edge because of no continuity of the lightsamples…
tell me…

If you use the vray image type you can render just about any size output
check here: http://www.chaoticdimension.com/forums/phpBB2/viewtopic.php?t=9982&highlight=vray+image+size
well
Big render script didn’t finish the job
about vray image type, can’t find it under max 5.1 and vray 1.09.03n
Does it exist on that version?
don’t think so, only the newer builds have it
I’m trying to render a test scene using that vray raw image type
Can somone please post a simple walkthrough how to use it?
My max keep crushing when i try a 10000*8000 render
You might get away with rendering as large as you can and then rescaling the image in photoshop using a program called Genuine Fractals. link to software manufacturer below

first:
you’ll have to set the max framebuffer (image size) to something very small - say 100x80 pixels
this is the major reason for the crashes - seems max always allocates the memory for this buffer, even if the max vfb is off and you write to disk directly (dont know the bit depth it allocates but assuming that the rendering is taking place in 32bit you get 300mb for the buffer alone)
then you enable the vray vfb and set the output res to the value you want
render to memory: off (save mem)
render to vray image file: on
generate preview: depends on the question if you want to get a preview
later you can open the vray raw file in the vray buffer (best would be to restart max first) and save to a more common format
ps: most of this is documented in the updated help files in your download account
ps2: since the memory of your machine fragments, it would be advisable to reboot first and try to eliminate background tasks
hope this helps,
Mike
Hi mike
thx for the reply
I mannaged to render the pic into vray raw image file
How can i open it in the vray buffer?
i don’t see any load option on it.
hi gilicom
you can load it over 3dmax -file-view image file and save it what you want
thomes
btw…did you break rendering with bigrender?
