Curtain texture

[bouhmidage]

light doesn't pass through the curtain , ( no sun light on the ground ) any help please ?? i used diffuse map as translucent map too.

Are you sure it doesn't? :)

[bouhmidage]

no direct sun light

Why would you go up to 240 oO?

I thought that this is a bit too bright white for proper rendering.

I try not to go higher than 190 max 210

But he has diffuse level at 0,8 so it makes it 192.

Bouhmidage, I'd suggest putting solid grey material on all objects except your curtain, deleting skylight, and seeing if the sunlight really doesn't pass through. Can you post the scene?

Correct me if i'm wrong, but afaik, materials doesn't pass light through, unless opacity and/or refraction slots have other values than zero.

I think translucency should also "transmit" light to the other side.

I think translucency should also "transmit" light to the other side.

It does, but it does uniform diffuse scattering, so it will scatter light to all directions when passing through, and light rays from sun will not maintain their original direction then. So you can use either opacity optionally mapped by texture of fabric, or refraction with mode set to twosided and refraction color optionally mapped by texture of fabric :)

That's why I wrote "transmit", not "pass". :)
I think this is the case why this thread's author has doubts about his material "passing" light through.

Using refraction colour mapped with fabric texture might produce strange results when using reflectivity (transparent areas will be still reflective). But it probably won't be visible anyway.
