Tips & Tweaks

• You dont really need to turn Refraction ON in many cases.

• You can store your Photon-Solution... so you don't need to re-emit photons
for every frame if you do a Camera-Animation for example.
• Play around with the Scatter and Extiction values

:::

You could also use a point or spotlight
If you use a Spotlight you should increase the Photon-Energy (Maya/Light Rollout)
to 20.000 or 30.000 in !

:::

If you dont like the rendered alpha-mask
(e.g. you have to put your object onto another background)
You could set a solid Alpha under 'Matte Opacity' of the Phong-Shader !

To colorize your Subsurface Scatter simply add an 3D Texture to the Parti-Volume Node's Scatter Attribute
(the one which is 100% RED )

in this case a color-ramped/remapped Volume Noise (MAYA builtin)

If you got area's like the following...

you can get rid of this :
• Increase the emitted Photons to approx. 150.000
(in some cases you'll need 2.000.000 Photons)
also increase the
• Photon Volume Accuracy
• Caustic Accuracy
And tint your Shaders-Diffuse and Specular Color a litte bit towards
the Scatter-Color !

:::

If you would like to see how your Photons are stored
(and how your object is filled up)
you can set the Photon-Volume-Radius to 0.02 - 0.1
and you will see something like this!

(5000 Photons emitted)
