Rendering 6810 x 4480 mm size banner!!!

[JayTee]

Hi,

 

My client wants a banner that is 6810 x 4480mm. Is it even possible to render this size image from 3ds max/v-ray? What DPI would be good enough?

Most print places would ask for between 100 and 150ppi at this scale. Which would mean rendering somewhere between 20,000 and 40,000 pixels wide in your case. There are lots of previous threads on here discussing how to handle large scale renders in max and vray if you do a search.

I had to do something even bigger. Best thing to do is find out how big they are printing it. There is a wall in which printing cannot add more detail no poiint doing it huge if the material it is being printed is not going to show a fine image. usually when cgis are being done for wall paper i do it 10,000 pixels by about 6000 pixels.

contact the printing company and ask them. 150dpi sounds too high to me.

for something that size i'd be surprised to find a printing company that used over 30dpi.

At 100-150 PPI you'd be in the gigapixels range. I wouldn't even attempt it. Figure out the most pixels you can reasonably do and contact the printing company.

region rendering, but include the whole frame, computer will embrace it as it was a smaller region, worked for me for 8000x4000 render, cheers

With all due respect I disagree. I strongly suggest you use strip rendering in backburner for rendering large static images.

I have earlier rendered 420x250mm 300dpi with 3ds max Blowup rendering. The render turned out fine, but there was always some problem with the lighting. The lighting was NOT even, when I stitched the four separate images into one in photoshop. The problem appeared close the seams of the images. The images had slightly different light/shadow darkness in those areas. I always had to do lots of Clone stamping to get it right.

 

I used these "official" instructions http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=5582404&linkID=9241177

 

What was i doing wrong? I used vray and I calculated global illumination for every individual image. Should I have calculated the global illuminations for the whole image first and then use that saved file in those four renderings?

When you submit a job to Backburner the network job assignment dialogue is going to pop up. In that dialogue is a check box that says "split scan lines". Click on that. You can then define the height of your strips etc. by clicking on the define button. Once you've done that hit submit and you should be good to go. Max/VRay will do all of the pre-calculation for the entire view (LC/IR) and send those pre-calcd. maps to you other machines on the Backburner server list. One each of the strips is rendered Backburner will stitch them all together automatically.

 

Hope this helps!
