cacheBlend

Go to: Related nodes. Attributes.

 The cacheBlend node corresponds to a nonlinear track. It can contain
 any number of cacheFiles over time, and controls their evaluation and
 weighting over time.

 To evaluate at a given time, the node determines which caches are active.
 It then does a normalized weighted blend of the active caches based
 on their weight and per-point cacheWeight values.

cacheData, disableAll, end, inCache, perPtWeights, range, start, vectorArray, weight

Long name (short name)	Type	Default	Flags
inCache (ic)	compound	n/a
Parent attribute for input cache vectors.
vectorArray (va) vectorArray empty vector array inputs data to be blended
perPtWeights (ppw) doubleArray empty Per-point weights for the cache. If unset, treated as all 1.0. The per-point weights are multiplied by the per-cache weight attribute and normalized against the weights of any other active caches.
disableAll (da)	bool	0
This attribute can be used to disable the blend entirely so that it does not evaluate any of the input caches at all. It does not modify the enable attributes on the input caches themselves.
cacheData (cd)	compound	n/a
Parent attribute for per-cache data.
start (st) time 0film The actual start frame for the associated inVector, taking into account holds, scales, trims, etcetera.
end (e) time 0film The actual end frame for the associated inVector, taking into account holds, scales, trims, etcetera.
range (ra) bool false Whether the input clip is in range.
weight (w) double 1.0 Weight for the cache. This weight will be normalized against any other caches on the track at the current time.
