Title: Render resolution - cannot render larger images
Post by: Oltskul on 2012-12-27, 11:39:06

Very simple, corona with my PC cannot handle rendering images larger more than 3Kx3K

this problem is very common for me - even in most simple scenes with one box and one light


pc: Q6600
ram: 6GB - around 4GB free
win 7 x64

Does enyone have the same problem?

what does the error say? Do you use the default internal resolution (2)?

It seems to be a feature, because 3k frame buffer with internal resolution 2 has about 800MB by itself. You can render about 2 times bigger images by setting internal resolution to 1 though.

so.. I got from 3K² 4,5K²...

any way - solution is to use computer with more RAM?

ok, that confirms it was this error.

Yes. You need at least 20 bytes to store 1 pixel, so you can do the math ;)

gotcha:)

so, some simple math:
1px@40bit and 6700px² is cca 1,7GB...

why does not Corona alocate needed memory? is there any another restriction?


Bit simplier solution.. Can corona split render into few blocks?

It's 20 bytes, not 40bits.

Anyway, there were some (universal) scripts for splitting large renders, if I recall correctly

Tried this one Super Render : http://www.forsolloza.com.ar/scripts/  without success, anyway it's not so important right now since it's an alpha stage...

we are waiting for new stuff it's christmas :p :D

ok... it was little bit weird... but the trich was to shut down Photoshop, Illustrator and FullHD movie playing on background...
Now I am on 5K res with lots of mesh ;)

Crop rendering is implemented now, so it is possible to use a script for rendering ultra-high-res images (with PT+PT)
