Shader Mixer Translucence node

meipe

Hi there,

Sorry if I start another shader discussion in such a short time, but I wondered if anyone knows how to use the Translucence node... The only reference I found is the online documentation saying, well, that the node exists. There is one Color and one Normal in the input... ??? I should have expected some value to control the amount, plugging the incoming color, and having the result as an output, but the logic must be different. Thanks! :)

Adding a Nf variable after unhide the hide parameter.

Use color in translucense for control amount and color in surface for color. It should be color because you can use an image for non-uniform amount of traslucense.

It is basically a diffuse with a reversed normal. Use it to light one-sided polygons from the backside, like leaves, shadow plays and such. Image: Translucency brick only with a shadow casting light from the back.

Thanks! So basically it does for planes what SSS do for volumes; but maybe on thick tropical leaves, light scatters a little sideways.

It shows the light that is falling on the other side of the surface. If the surface is part of a solid model then no light will reach the back of the inner surfaces, so there will be no effect.

Superthanks!
