Hello,
I was wondering if there were any suggestions for rendering large image? I'm rendering an image at a scale of 9600 x 5400, but I don't know what settings are good or bad for a render like this.
I noticed the tile size is really small at the default settings, but not sure if something like that matters in terms of quality.
Is there a common work flow to follow?
thank you

Re: Large Print Rendering tips?
render settings are render settings, that shouldn't matter if they're set properly. It's just going to render for a long time ;)
if you have access to a renderfarm, you have options there to split up the frame into multiple parts, to be reassembled later on.
and, just guessing here it's for print, have a look if you really need the large size. e.g. print for abri's often is just 75dpi.
i can recall some tools to create multiple camera's of the scene and render parts on different machines for manual stitching later, but cannot seem to find it so far....

Re: Large Print Rendering tips?
For Print > 200 Dpi with an insane number of pixels you should also consider to drastically lower your renderer AA settings because the dots are so small you don't need them to be antialiased ;-)
Re: Large Print Rendering tips?
And in addition to that, you could try rendering in a lower resolution, and upres it in Photoshop. Often you can hardly tell the difference ;)

Re: Large Print Rendering tips?
you need to know your output size, there is a formula for that.
For example if you have to print an A4 which is 21x29.7cm you would have to produce a render like this: 21*300DPI/2.54 = 2480 pixels X 29.7*300DPI/2.54 = 3507 pixels
Your render then will be a 3507 x 2480 pixels to print an a4 at 300 dpi.
Many other prints like highway publicity and stuff like that are so huge that are made to be seen by far, you wont need 300 dpi. It depends what your client or you need to do with the output.
Basically you need to know at what DPI your output is and the measure. Then the formula is "dimension x dpi / 2.54" = your output pixels. you have to do it for both sides ofc

Re: Large Print Rendering tips?
the most valuable tip is to turn off the display when rendering in the preferences. you will not believe how much ram takes out of your graphics card just to hold and display a large format image from memory.
Gossip is what no one claims to like, but everybody enjoys.
Re: Large Print Rendering tips?
Sorry for the extremely late reply... But thanks for the help!!.. very useful, very helpful. Thank you so much for the help. Everything came out lovely.
Something I did to get the correct size and DPI was create the Canvas in Photoshop at the size and DPI needed, then test renders until it fits somewhat in the canvas setup, then upscale it to fit perfectly.
Again thanks for the help

Re: Large Print Rendering tips?
This works like a charm if you are rending XXL images, especially if you want a high DPI. I have used it multiple times.
