Exporter wont render more then 3 frames

[matej]

Hi yall!

I have this obscure problem when trying to render an animation (Blender 2.65.0, exporter 1.19.6). Right after finishing the second frame and starting the third frame (the third in sequence of any combination of start - end) this error pops up:

Code: Select all

....
OpenEXR-writeTile: ERROR: Failed to write pixel data to image file "/tmp/test2.blend_Scene_rnd_Main.exr". Attempt to write tile (0, 0, 0,0) more than once.
Octane plug-in v1.19.6 on 2.65.0 : Launching Octane: ....

The third frame is then renderer & saved correctly, but then the exporting process halts. I have absolutely no clue where this request of saving to .exr is coming from (is this some auto-save thing?). I have the compositing & sequencer disabled and in the Octane exporter I'm saving to .png

Has anyone encountered such a problem?

ah, nevermind, solved

In Cycles: Render -> Performance -> Save buffers must be disabled
