add 'Headlight' option (flashlight attached to camera)

Hi all,

I know there is an option to create a headlight just behind the camera.
Right now a headlight can only be set 'by accident' when you try to render without any light in the scene.
My wish is that it would be an extra option in the 'add' menu.
Also: right now the headlight is a pointlight by default.
Could it also be possible to have a spotlight or directional light as headlight?

I would use that to imitate a 'flashlight' of a photocamera.
MLT right now works great but it has difficulties to get darker indirect areas noise free. Just as in real life a flsahlight on the camera would be usefull as a fill light to get more direct light in the scene and speed up the rendering.

Cheers,
kwistenbiebel

Couldn't you align to the cameras view, zoom out [as in back on the axis of the camera] just a bit, and insert a spotlight?

Hi all,

I was browsing some galleries on the Maxwell forum the other day and stumbled on a thread about interior rendering making use of a 'flashlight' on the camera.
They modeled a vertical plane of about 2X3 cm and placed that right above the camera with an inclination of 45° using an emittive material with intensity of 300 Watt (colour white).
This creates a real simulated photoflash light.
In the maxwell renderings the rendering time got better using this because the flash light exposes those indirectly lit areas that would take forever to compute.

Would it be possible (wishlist) that KT attaches automatically such a small sized 'vertical plane' to every new camera that is created?
I am wondering if this method could speed up MLT in Kerkythea as well.

Cheers,
Kwistenbiebel

I know Claudio was always pussing to making such a tool.
Although there are many things to do till next release (and
I would say that the list is closed) we can give it a shot.

[regarding vertical plane, i don't see any benefit from it
besides increased user productivity]
