NX Lightworks Render Foreground Effect

GEA Farm Technologies 2 2013-01-15 NX Render Effect - Light Scattering - Ahrens

The Setup / German dialog

GEA Farm Technologies 3 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Without any effects

GEA Farm Technologies 4 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Light does not honor effect by default!

GEA Farm Technologies 5 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Light has to be assigned to effect!

GEA Farm Technologies 6 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Be carefully with attenuation!

GEA Farm Technologies 7 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Extremly high/low values points out effect

GEA Farm Technologies 8 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Density & Attenuation have to be adjusted together!

GEA Farm Technologies 9 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Sometimes a smaller effect sets an attedude!

GEA Farm Technologies 10 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Lower values

GEA Farm Technologies 11 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Lower noise can simulate smoke

GEA Farm Technologies 12 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Fine dust

GEA Farm Technologies 13 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Dark and schematics

GEA Farm Technologies 14 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Increase Noise Scale

GEA Farm Technologies 15 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Too Dark in the night with higher Attenuation

GEA Farm Technologies 16 2013-01-15 NX Render Effect - Light Scattering - Ahrens

In this case more Samples have no effect!

GEA Farm Technologies 17 2013-01-15 NX Render Effect - Light Scattering - Ahrens

But the Noise Scale is one key value!

GEA Farm Technologies 18 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Everytime in conjunction with Attenuation!

GEA Farm Technologies 19 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Simulates strong lights

GEA Farm Technologies 20 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Maybe a little bit too much?

GEA Farm Technologies 21 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Back to lower effect by lower attenuation

GEA Farm Technologies 22 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Density up and change of attenuation

GEA Farm Technologies 23 2013-01-15 NX Render Effect - Light Scattering - Ahrens

Density down and increase noise scale
