VrayLightSelect to VrayLightMtl

I was wondering if there was a method to select all your mapped vraylightmtl’s in an element for post purposes.

The case is loads of LED’s rendered as vraylightmtl’s and we want to add some glow in post and therefore need the selection.

Note: They are glowing through an acryllic (glossy refractive) plane!

Adding your V-Ray Light Mtl in a V-Ray Material select render element should do the job.

Of course, thanks.
