VRAY render time increases

[jakobhallsson]

Hi. I am having trouble figuring out what my problem is here.

I'm doing a render of a light going in a circle. The entire render is basically the same. Nothing really changes except the intensity of the light and the position.

The first frames take less than a minute to render, but the last frames take almost eight minutes per frame. I don't understand it

Waiting through a frame I notice that after it does the prepasses it takes ages before it starts the actual rendering. In the beginning of the render, this happens almost instantly.

What's going on here?

Maybe the data is written to the hard disk, so it takes longer to write-read than using the ram memory.

Try lowering (or raising) the dynamic memory limit, maybe it will fasten up the rendering.
