I've read the manuals but... with indoor lights and reflective surfaces, they seem to appear no matter what tweaking and render kernel I try. Any tips on how to deal with this problem?

I think they are a function of having glossy or specular materials with too much reflection. But the easy solution is to put Image->hot_pixel to 0, and increase Kernel->Caustic Blur is any till remain.

Thanks for the help. There are some windows in the scene. The default free shader had opacity set at 100% which just made the glass a mirror so I reduced it to 12%, sort of what I did in Poser/firefly which improved visibility through the glass and let more light from the outside into the room. I did try changing the caustic blur, but in the wrong direction, to zero, duh Increasing is helping a lot. In the reflection node the entry is an rgb color, white. I wouldn't know how to reduce it unless that would be changing it to a gray? Sorry, I'm using path tracing and I don't see an entry for hot pixel.

Ok I found the hot pixel entry in imager, I almost never go there lol
