Shiny decals are extremely bright after compilling cubemaps

[TFlippy]

I've noticed this strange problem when I was looking around my map after compilling Cubemaps with HDR enabled. Shiny decals, such as the CS_Office paintings and puddles don't have the properly generated cubemaps applied to them, resulting in broken extremely-bright shine that breaks HDR by making everything dark around it.

Is there any fix for that except for removing them?

iirc you have to set mat_specular to 0 then do two passes, one with hdr disabled then one disabled, and you have to reconnect between the two

But I haven't done mapping in years this may be wrong
