Another question about the trench I’m making (sorry!).
The current file renders a 640*480, oversampling 5 jpeg picture (no motion blur) in under 2 minutes. Fine.
Then I added some tower-mounted cannons to the main surface of the death star, in a line running along one side of the trench.
Rendering time still under 2 minutes (probably, in any case not noticeably increased) - fine.
Then all I did was I duplicated the line of towers, and placed them along the opposite side of the trench.
Rendering time is now over 12 minutes ! (I haven’t actually timed it because I’m too impatient to render anything that takes longer than it takes me to eat my dinner! ). The picture doesn’t even begin to appear in this time. The black picture screen appears, and the computer’s thinking light flickers constantly, but that’s it.
This sudden increase should not happen, because :
- The new meshes aren’t that complicated.
- Compared to the number of meshes making up the death star surface itself, the number of tower-mounted cannons is negligible.
- Just to see if there was a limit on the number of renderable meshes or something, I duplicated the entire side of the trench several times (making several hundred new meshes), and there though rendering time was increased, it was not by much.
I am at a loss. I seem to be doing more wrestling than rendering with Blender lately. Can anyone help ??
