I am working on an OFX plug-in on Nuke which requires sequential
rendering and I would like to find a way such that the plug-in may
invalidate the cache to maintain continuity or re-render if necessary
(e.g. the user drags the timemark in Nuke).
Have you declared the plugin property
kOfxImageEffectInstancePropSequentialRender?
What do you call "the timemark in nuke"? The key value of a parameter?
If you modify the time position of a parameter key and your parameter is
declared with kOfxParamPropCacheInvalidation=kOfxParamInvalidateAll,
your cache will be invalidated.
I have tried to set "kOfxParamPropCacheInvalidation" property on
parameters but with no success.
In all cases, you can force the cache invalidation by declaring an
"IsSecret" parameter that you modify when you need to invalidate it.
