Why am I receiving different results from the same model settings?

The ClimateStudio engine relies on Radiance. Radiance simulations are stochastic, so ray samples are inherently random. This means that the way scenes are sampled in each simulation will vary to some degree.

In general, setting ClimateStudio to use more passes will allow the results to converge about some “true” value. For more information about this process, read our internal validation study.
