Our biggest headache during production, is dealing with the c4d render queue, for any project with many texture images.
When a native c4d render engine project uses an image sequence texture (eg 2000 jpg images for a tv screen in a room), it only ever checks the first frame of the sequence, and simply assumes that all the other frames will be present. when doing this in octane though, every texture frame is checked one by one when adding a project to the render queue. You can see this by checking the c4d built in project asset inspector, this mirrors what the render queue is doing behind the scenes.
So, if I add a c4d engine project to the render queue, it might take 5 seconds to load the scene and add it to the queue. If I do this with an octane project, depending how many textures I am using, it will take 5-20 minutes to add the project into the queue. Until then c4d is frozen. Doing this maybe 4-5 times for different camera angles, takes, passes, versions... I can wait an hour to add a few projects into the render queue.
Is there anything that can be done from your side? something in the c4d api to say "hey, this is a sequence, dont check every frame, trust me" rather than the current "here's 2000 textures, check them all please"
