Re: Render In Image and params



OK, I now get it - it doesn't matter whether I loop inside of QC or outside - the Render In Image patch (RII) seems to get drawn after all of my calls to renderAtTime...

Can you explain this bug in a little more detail so that I can understand. I know that you mentioned that a work-around is unlikely but I really need to get this working. :-P

It's a synchronization issue regarding the use of the pBuffer's content as a texture, so it's really not something you can work around.
However, you can use 2 QCRenderer and have you own pBuffer rendering system: use a CVOpenGLBuffer to render the first QCRenderer into, then pass the result to the second QCRenderer on an image input.


See the Performer sample code for a starting point.

It'd also be useful to know if the bug has been fixed and if we're likely to see the fix via an update soon. I can probably live with the problem for a short while.

Unfortunately, I cannot comment on what's gonna be or not gonna be in a software update
