PPL files are lightmaps (per-pixel lighting) generated by VRAD for prop_static models that have generatelightmaps enabled. Unlike brush lightmaps, PPL files are always 24-bit 
SDR, even when the map is compiled in HDR mode.
Important:To account for potential discrepancies between UV maps of LoD models, PPL files contain a lightmap for each LoD model. This can greatly increase the file size of a map if a lightmapped model has several LoD models!A PPL file can be converted to uncompressed VTF(s) using Ficool2's proptexelvtf.exe, which can then be used for $lightmap.
