I don't know 'bout the tutorial, but can tell my workflow:
1. Create animated scene. Assign named materials. Setup UVs, cameras and assign dynamic textures if any (I use image sequences and not sure about the video files).
2. Use Render Image to load your scene 1st time in Octane — you can setup materials and environment there. If you gonna change dynamic textures — make sure that you use texture from Octane project's folder — Yoyoz's (God bless him!) exporter will replace it frame by frame during rendering animation. Notice that if you turned on "motion blur" for camera and "export camera" in exporter's settings tab any camera manipulation in Octane will hardly blur your scene due to... motion blur. )) Save Octane scene. Close Octane (choose Save again if it asks).
3. Switch to Blender and choose "Render Animation" check-button. Setup folder
— not filename
— to output image sequence, set samples amount to calculate, choose file format (1.12 version of Yoyoz's (God bless him!) exporter). Save Blender scene.
4. Click "Render animation" button and enjoy it goes. =)
I noticed that somewhy export process can stop at some frame — simply restert Blender and continue from the next frame after last rendered.
Also refer to this discussion about rendering .obj sequence
Feel free to ask any quesions concerning rendering animation with Blender + Octane if you'll have problems with the process. =)
