I. Lights

Lights parameters:

In the Main panel, use the dropdown "Light type" to change the type of your light. By default, Softbox :

Position : Accurate / Normal / Estimated (Default)

Method used to compute the light position:

• Accurate : The light will be positioned accurately so it's reflection will always be under your pointer.
• Normal : The light will be positioned perpendicular to the normal of the face under your pointer.
• Estimated : The light will be positioned always facing the direction from your pointer to the center of the bounding box of the object.

Options :

The blender lamps options and the softbox (mesh light) have some differences :

Point/Sun	Spot	Area	Softbox

Target : object that will always be targeted.

This is useful if you want the light to react to only one object and ignore all the others.

Range :

Increase or decrease the distant of your light from the targeted object.

Shape :

Area: Change the shape of the Area from square to disk or rectangle or elipse.

Scale xy:

Softbox // Area : Scale your light on the X or Y axis.

Keep ratio:

Softbox : The strength of the light will be adjusted accordingly to the size of your light. Useful for adjusting hard or soft shadows.

Cone size:

Spot : Scale the size of the cone.

Blend:

Spot : Soften the edges of the cone.

Shadow:

Point // Sun // Spot : Soften or harden the shadow of the light.

All lights:

• Rotation : Rotation angle around the target on the Z axis.
• Tilt :Rotation angle of the light on it's local Z axis.
• Pitch :Inclination angle of the light around the target.

Round Shape : 0 --> 1

Softbox : Smooth the edges of the Softbox to change the shape from square to round.

• 0 = Square
• 1 = Round

Segments : 1 --> 100

Softbox : Number of segments to smooth the edges of the Softbox.

Soft Edges : -inf --> inf -inf --> inf

Softbox : Soften the edges of the reflection of the light. This does not affect the energy, only the reflection.

Softbox (Reflection only):

• Soft Edges : Global value to soften the edges of the reflection of the light.
• Edges :Outer and inner values to soften the edges of the reflection of the light.
