My render times for the same scene, using the same settings keeps increasing. I have a simple file of about 1.3 megs consisting of linked assets and characters from seven source files. When I render a distant camera show it took approx. 4:28 minutes. I set to slot 2 and render the same thing. It took about 5:03 minutes. Next slot 5:15 and fourth 5:28. Does anyone know why? When I first noticed times were going up, I reran the renders four times in different slots with only blender app running. I am processing on an I7-4790k with 16 gigs memory. This render is using everything it can find up to 14.7 gigs of memory. I decided to retry this with a simple 5 frame animation. changing nothing. Times are still increasing frame to frame.
I next ran a five frame animation to see what would happened. No animation data in file yet, just producing png files. They started at 5:40 for frame one and increased upward to 6:23.
I do have a lot of textures. I am using particle hair on the characters. One is quite heavy being a dog.
Any thoughts why it would keep expanding time. I haven’t tried to optimize the render times yet, but if each rendered frame keeps increasing, I’ll be dead before it finishes.
Has anyone else experienced this?
