Long pause between rendering frames

[jkontiola]

Im rendering an animation. The frames take like 10 secs to render. After that the renderer takes a long pause before starting to render the next frame. Why is that and can i make it start rendering the nex frame faster?

This is what console sais before and during the pause between frames:

Whats the export mode? It's it exporting new frame data?

[jkontiola]

Its

HEX

Global TMP directory

Separate files

[bdancer]

I mean "Animation" mode. If it's "Frame By Frame" then it's just a new frame export.

[bdancer]

I'll need full log and scene for further investigation.

[jkontiola]

Well I tried frame by frame and full range

[jkontiola]

here is the log

[bdancer]

I see only one frame rendered there, so I can't find any slowdown between frames...

Ups sorry, after the line:

I'll need a scene to reproduce that.
