Hi DamirH,

can ou expand on how to set this kind of material up please? Managed to find the ‘Thin Translucent Material’ from the palette but have no further idea how to integrate this into my existing material?
it has an input for a transmittance colour but not sure what goes into what here;)
it is for a glass headlight.

thanks for any guide on this.

Best
Dan

EDIT** found the shading model ‘thin translucent’ option on my material node. but not sure on how to go about integrating this into my exisitng material for my headlight. any help woul be appreciated.

Hi Dan,

To use the Thin Translucent shading model, do the following:

• Open your Material and in the Details panel, set the Shading Model to Thin Translucent
• In your Material Graph, add the **Thin Translucent **expression node.
• Plug your base color or color texture into the Thin Translucent expression.
• On the main Material node, use the roughness, metallic, and opacity values (like you normally would) to control the rest of the tinted material.

This is a test image I created when trying it out. The right is using a traditional translucent material that is not physically accurate. The left is the Thin Translucent shading model. I don’t have UE4 up to grab a screen shot of the material at the moment. Very simple to set up something like this using the instructions I listed above, which is what the ones in this image are using.

Hope this helps.
