Anyone got an idea how to animate DOF with Blender's exporter? Focal depth, camera and target objects are set, but octane doesn't change focus automatically. Every time I press the "select" button in the exporter, the focal depth values are taken from the target obj and focus is good, but when animating it doesn't use it even if I hit the curve implement button.

Yes it was a turntable animation. And yes of course I could turn off the AF, but again...that would give me a static DOF. If I want to have a dynamic DOF I either have to turn on the AF, or I have to actually animate it in Cinema. The problem with the first option is obvious. The second option takes a very long time as octane has to load the entire geometry between each frame. With this complex geometry that takes a very long time. This is why a rudimentary keyframer would make the entire process much more efficient. Another example, in one of my next animations I will have a light emmiting sphere enter the largest vessel, and have the camera fly after it, thus creating a a flythrough through the entire vessel. This can only be animated in Cinema and the rendered out in Octane, but as said it means each frame has to be loaded seperatly, costing an emense amount of time. If I could have a simple keyframer for position of the emmiter and the position of the cmera, I could render the whole thing in a third of the time.

Well, the main problem is that it takes a long time to load and voxelize the scene, not the missing keyframing. We may add some simple keyframing for camera animations, but if you for example have a light flying through the scene this approach doesn't help anymore.

As soon as we have the features for 1.0 final we will look into optimizing and speeding up things. Until then our main focus is at the moment to make things work, that need to work.

In my opinion, instead of a simple keyframing for camera it would be more interesting to have an exporter like fbx that store also the animation data. I prefer to animate in my host app (cinema 4d) ;)

p.s. great work cglittenberg, sorry for hijacking
