One important detail is that the CPU Id has to be different for each MXI file. The CPU Id represents the noise seed and is assigned randomly to each render when it is started. If the CPU Id was the same, Maxwell would have calculated the same noise pattern and the same light rays, so the result wouldn’t be complementary.

Calculating the number of identical nodes needed to get a particular final SL. Most of the times you won’t need to calculate anything or Maxwell will do it for you in a cooperative network job, but maybe this calculation is useful at some point; it lets you know the SL required for each node to get a particular final SL when merged, provided you know the number of nodes involved and that all the nodes have the same computing power: SL_NODE = ( log(((exp(SL_TOTAL * log (1.5)) - 1.0 ) / nNodes ) + 1.0 )) / log(1.5) log = neperian logarithm Which is the same as this in a more visual way: |
