Translucent Material comparison

[Fletch]

This is a comparison of the Template Translucent and similar materials, in this model used as a cover on a pergola.
This shade canvas model on top of the pergola is a single rectangular face 1 inch above the wood of the pergola model.
These were rendered in Easy 04. Medium render setting.
The face was painted with 90% grey color and then the Twilight Render material template was applied.

Thx Fletch, This help a lot. Does this material templates give similar results with thickness ?

[Fletch]

No, for modeled thickness, results will vary.

Use the Template>SSS for thick models, the SSS template can look fantastic but render times are much longer and the results are best with Easy 09 or 10 render setting.

Here's an example of a 2mm thick glass lamp bowl pendant that comes in the Twilight Light Components for V2.
Here is the default material and how it renders.

Here is the Translucent>Thin Curtain Material template applied to the lamp glass material instead. The difference is that we have CHANGED THE "Translucence" variable to be 100 changing from the default template value for Thin Curtain of 30.

It renders quickly, and looks good.

Keep in mind that in this large ceiling bowl pendant lamp there are 4 point light sources each at 1750 lumens output. See screenshot for settings. (RIGHT-CLICK>OPEN IN NEW TAB to see FULL resolution image)

2mm thick glass lamp with Template > Frosted Glass > Light
The advantage with this one is that the point light object for Twilight Render looks like an actual light bulb.

When to use "Lamp Glass" template?
The Lamp Glass looks like a nice "frosted glass" material when there is NO THICKNESS to the model.
So, use it with a single face model of a lamp shade.
If you have a model with a thickness, then just hide the innermost face of the lamp shade, so that the exterior face is the only one that will render.

When to use "Frosted Glass > Heavy" template?
The Frosted Glass Heavy looks like a nice "frosted glass" material when there is NO THICKNESS to the model.
So, use it with a single face model of a lamp shade.
If you have a model with a thickness, then just hide the innermost face of the lamp shade, so that the exterior face is the only one that will render.

When to use "Frosted Glass > Plexiglass" template?
The Plexiglass looks good when there is NO THICKNESS to the model.
So, use it with a single face model of a lamp shade. Plexiglass template obscures the light objects more completely than "Heavy".
If you have a model with a thickness, then just hide the innermost face of the lamp shade, so that the exterior face is the only one that will render.
