Limit the maximum number of diffraction paths computed per emitter, excluding the direct/transmission path. The acoustics engine searches for up to uMaxDiffractionPaths paths and stops searching when this limit is reached.
Setting a low number for uMaxDiffractionPaths (1-4) uses fewer CPU resources, but is more likely to cause discontinuities in the resulting audio. This can occur, for example, when a more prominent path is discovered, displacing a less prominent one. Conversely, a larger number (8 or more) produces higher quality output but requires more CPU resources. The recommended range is 2-8.
