First of all, kudos to Emmanuel and SH3D co-developers for creating such an amazing software. I have been using it for last 2 months and I find it very useful.

In order to share my designs I am creating Q4 quality (Best) photo realistic renderings of the houses I have built in SH3D. Everything works fine but these rendering are very slow.

I would really like to speed up the Photo Realistic rendering process. I have tried extending the memory using the technique mentioned in http://www.sweethome3d.com/support/foru ... hread,1460, following are the results:

Windows 8.1

a. Created a text file named SweetHome3D.l4j.ini in the same directory as SweetHome3D.exe, and wrote the max memory Java option (-Xmx2048m) in that file - No effect on speed of photo realistic image renderings

b. Created a text file named SweetHome3D.l4j.ini in the same directory as SweetHome3D.exe, and wrote the max memory Java option (-Xmx4096m) in that file - No effect on speed of photo realistic image renderings

Linux(Ubuntu 14.04)

a. Edited SweetHome3D script and update the 1024 value in the option to -Xmx2048m - No effect on speed of photo realistic image renderings

b. Edited SweetHome3D script and update the 1024 value in the option to -Xmx4096m - No effect on speed of photo realistic image renderings

I even tried adding start memory Java option (-Xms2048m) independently as well as along with above mentioned changes but no luck.

Kindly let me know how to enable the extended memory changes and whether I am missing something.

Thanks in advance.
