Daz Studio Headlamp reflection

Coryllon

Is there a way to prevent the headlamp from causing a reflection in mirrors and other shiny surfaces? I have seen it a few times now. It tends to wreck an otherwise good render, sometimes I can get away with a post render touchup. othertimes I can not.

With Iray the setting is in 'Render Settings - General - Auto Headlamp'.

If you're using cameras then each camera has it's own Headlamp setting.

Recommend -: select Camera, set Headlamp Mode to 'Off'. As prixat mentioned, set Auto Headlamp to 'Never'. Use Spotlight, ghost light, etc., then you're still able to tweak the position of the lights to prevent them from being reflected on specular surfaces.

I've started to adress those issues by thinking of how to solve them with real life cameras.
A camera headlamp is like the flash on a camera. So what would you do in real life, to avoid reflections of the flash in a mirror?
I'd try to switch off the headlamp while increasing the Film ISO value and adding a Vignetting of (let's say) 24.
You could set the Spectral Rendering to Natural, cie 1964

Appreciate the suggestions. The camera headlamp is what I use when no other light source will work. I take it I am stuck with them?

If you wanna have high quality light in your scene, use various of lighting patterns with ambient light, mesh light, ghost light, etc. rather than a 'Headlamp' which is with very low quality and no potentials for tweaking.  It's a 3D world, you should know how to well place lighting sources into your scene...

This redundant - the Autoheadlamp option will apply anyway, unless you choose to override it.

As for the question, it would suggest turn the headlamp off, parent a light to the camera and then use the technique here to make it a ghost light Creating a "Ghost Light" - Daz Studio 4.21.1.26+ - Daz 3D Forums . The obvious drawback would be that, unlike the headlamp, the light would not automatically switch if you switched cameras.

What do you mean 'override', how to do that ? 

Headlamp only works with Dome and Scene and Scene Only mode. If you set Auto Headlamp to 'Never', even with the default Headlamp Mode - 'Auto' on Camera, there'll be no headlamp. Headlamp Mode - 'On' will override Auto Headlamp property.

Would setting it up with the light parented to the camera then copying the camera and light for the new camera work? Then moving and placeing the new camera would also place the light.

You'd need to duplicate the hierarchy, or save as a Sceen Subset and merge back in.
