I think you're getting confused by the rounding errors:

Code: Select all

****Event Started****
Scrubber Time - 0.03999999910593
I think this is frame # 0


The time in Octane is represented in floating point. For example if you have 25 fps, the frame duration is 0.04 seconds. In floating point this is represented as 0.03999... . If you then use math.floor(currentTime / frameTime), you will always underestimate the frame number. What you should do is have an epsilon and if you're close enough to the integer, clamp it to the integer. I know it's subtle but there's not much we can do here.

But octane.project.getSceneGraph() will always return the root graph of the original project. You can get around this by getting the parent graph of the scripted graph which is always the correct one.

cheers,

Code: Select all

graph:getProperties().graphOwner

Code: Select all

function getFrame(currentTime)
   local halfFrame = frameTime/2 -- Force fix rounding errors
   return math.floor((currentTime + halfFrame)/frameTime)
end
