hi David,

the problem of "spikes" is already solved, but a bigger problem appeared :-)

i´m trying to render some passes, i have several area lights in the scene with mia_photometric + ies profile, but the diffuse pass only show me one of the lights...the original render is fine.
everything looks good, but when i open in Nuke the .exr file, the Diffuse and Beaty pass, don´t show all light projection!! see image attached.

thanks

p.s. sorry my english :-)
