Quote - dpi?!
it has NO meaning in digital output, WTH would they ask for 300 dpi and a pixel size?!

DPI is only for print

Pixel is ONLY for screens

(unless some expert knows better, that's way it works far as I am aware)

WHen making an image or video, you set it for EITHER:

pixel size

OR

a real world unit (like A4) and DPI for print

never both.

 

anway, it's a huge render size, so unles you have a lot of RAM or a simple scene, you'll have problems

 

Yeah, I actually know this. And yes, that's for printing (didn't i mention it's for an editorial project?), the size of each image must be 47x35 cm which corresponds to a little bit more than 5500x3500 pixels wide. (5616x3744 if including the bleed area of the book). I'm not only doing the 3D but also the book graphic project and stuff related.

No simple scene and not a lot of RAM either. lol. And the budget is down low if you really wanna know, which makes the option given by thd777 not available at the moment.

Thanks anyway man!
