confused   Rendering speed is extremely slow comparing to a similar image.
Hey Everybody,

I'd really appreciate if someone might have some insights regarding this issue.

I can't understand why when i'm rendering 2 different models with a generally speaking similar size and content (both models are of art galleries, both have ceiling and floor textures)
One of them renders relatively fast Model A - 13m20s
The other one is for some reason much much slower - Model B - 1h33m5s
For both I am using the "Simple photo rendering 2.0" plugin with the same conditions and rendering settings:
1,500 x 1,000 px, Quality: 4, default lens, same time of day, no ceiling lights or sky lighting and SunFlow rendering engine (with exactly the same settings).

When I use the "Simple photo rendering 2.0" plugin and chose Yafaray as the rendering engine the difference is very similar.

I'v even tried to turn off textures for both ceiling and floor and even switched off the pillars but it feels quite the same.

Any idea why would the difference in rendering time with the same method for a similarly empty space would be so dramatic ??

When I use "Yafaray Rendering-1.3" it does appear to render faster but as it is impossible to render with it multiple photos
it is not useful for me because I can't leave a batch of points of view to render over night..


Many many thanks,

Elis
