RENDER PROBLEM BY SIZE

[SKYFLIGHT]

Hello, first of all I apologize for my English I used google translator.
I am doing the design of a passenger ferry, but when I do a render dining xopn furnishings (25m x 35m) or Show hall (25m x 20m ) or aft of swimming pools, is performed only at low quality. When I want to put me iluminaciony relizmo cross instead of the image.
My CPU is an AMD FX 8320 with 4GB RAM 500GB two discs one mother MSI 760GM-P23 FX.
I will appreciate any help

What operating system are you using?

If you're running a 32bit version of Windows, you may want to increase the maximum Java stack size. (The default is 640 Mbyte, but you can increase it to 1 Gbyte safely -- and possibly a little larger.) See the information here.

Thanks, I realized the file that told me, and I went modifcando to test the behavior. I managed to successfully increase up to 1.5Gb, noting instability. Therefore I reduce during 1024 and will raise the issue for rendering.

Here I leave the copy of the file SweetHome3D.l4j.ini
