Going to try and explain this one the best I can and hopefully someone had the same issue and maybe has a solve …
working inside BFX with handles
range set to “media range”
dozen layers inside Action with some tracking (perspective grid, planar … etc)
motion blur on (doesn’t make a diff if off)
every single time at frame -1 when rendering, all layers jump and shift out of position
happens only when I render (write to file), scrubbing or stopping on frame -1 is fine
no rogue keyframes in animation editor
setting a single keyframe on surface Axis in order to force it to stay in place does not help
restarting Flame helped once but now that does not solve the issue
Any help is always appreciated!
Thanks all!
I.

Hi Igor.
I’m not sure I’ve seen exactly this issue, but I have had issues with BFX, if there is any slipping involved in the timeline. My weak solve has been to just copy all of the BFX nodes into a Batch group (not BFX), render and put in the TL.

PS … different BFX, different project, different system … same problem. Seems easily reproducible.

Hmm… Sounds like a ticket for support. I’d love to see these issues resolved as well.

Do you per chance slip the clip with bfx so the ranges change? I vaguely remember an issue with that.

That’s what I was talking about. I’m confident that BFX slipping causes problems.

No I didn’t … the only vaguely common thing with these Actions is tracking (of some kind)

I have seen this, now that I recall. The only solve I found was to do it in Batch, sorry.
