My dynamic CP map keeps generating white blinding light when I build cubemaps with HDR checked. I've compiled and rebuild the cubemaps multiple times. After that failed, I decided to uncheck the HDR box in the run map window, and build cubemaps again. I haven't had a problem so far since I ran the map outside of Hammer a few times. The compile log has no errors except for the "can't load skybox file skybox/<skynamehere> to build the default cubemap!" error.
