Since for my proyect I need octane to do flythrough animation I created a python script for blender that saves the camera position on each frame and then runs octane for each position.
Usage:
- Export your .obj file as you would normally do.
- Import into octane, change all settings you need to render your scene and save into a .ocs file.
- Open your blender original scene, copy the script below and paste it into blender's text editor, change all necessary Variables (fully explained in script).
- Hit Alt + p over the text editor.
- Check the console, the last line should read "export finished", if not, it will show where the error is.
- Run the .bat file
- Return a couple of hour later to see your results
.The script:
- Code: Select all
#Octane export camera script, writes a bat that launches octane several times for animations
#Thanks to Dave Jarvis, for the inspiration
#Made by CGgap in blendeartist, Curious Guy in Octane forums
#Known issues:
# -The export bat is generated in the disk root
# -octane has to close every time a image is rendered
# -Camera and camera target cant be parented

Limitations:
- The export bat is generated in the disk root
- Octane has to close every time a image is rendered (Radiance: There is a way to avoid this?)
- Camera and camera target can't be parented (actually i'm not sure of this)
Maybe I will also add blender to octane conversion lens and changing .obj file between frames.
Here is a little example:

Ok, it's staring to get late here, must go to bed
Cheers
