probeUpdateBudget property

int probeUpdateBudget

How many probes the blend and filter passes refresh each frame. 0 refreshes all of them. Lower values amortize the cost over more frames and converge proportionally slower.

A nonzero budget under a moving light produces a visible update wave crossing the scene, so it is a quality tradeoff rather than a free win.

Implementation

int probeUpdateBudget = 0;
