I did this render (WARNING: NO NUDITY!!! OMG! does that mean you won’t look?)

http://wancow.deviantart.com/art/room-for-two-348644476

Anyway, I’m hoping someone could clue me into what kind of settings I need to get the lamp shades to look more like this:

The bulbs in the lamps have UberArea light applied…

I tried applying transluscency and 90% opacity to the lamp shades, but I couldn’t get them to pass light through them and become illuminated.

Maybe put a light in the lamp ?  In Bryce or poser I would put a small light inside and adjust the fall off

What I do is use ShaderMixer to create a shader for the shade that uses a Ray Type test brick (Functions>Utility>Ray Tracing) to vary the opacity - low for transmission rays, higher for others. That, plus translucency, can give a good result for things like lampshades which are not served well by the standard shaders.

This is where I’m at at the moment…

This is the very first time I’ve enabled the shader mixer tab… I’m… a little lost smile

I shouldn’t be, but I be a wee bit lost smile

The brick should be testing for Transmission rays, and it gives a true/false output - you need to feed that to an If/The/Else brick (Utility>Control) with the colour for transmission rays (dark, as we want it more transparent) and others (light, so the shade isn’t see-through).

Richard’s way is the best…but you can get ‘passable’ results with using UberSurface on the shade…turn down the Diffuse strength (to about 30%) and turn off things like ‘velvet’, sss and so on…just use translucency….and set it to something like 70%  (Diffuse + Translucency = 100%).

No, it’s not quite the same, but is a quicker ‘fake’...

Just because something costs a lot, doesn’t mean it’s the best…

It just means it’s expensive.

I got sidetracked with Wendy’s new undies for Genesis… I’m easily distracted by sparklies smile

I think I"m going to focus on doing it Richards way…  or at least try…

Its too hot for timtams ;  ) lol…at 39 they just melt before you pick them up unless you stick them in the fridge.

I’m also into shadermixer…the more I find out the more I realise how much I don’t know…

I am so scared to ask, but as I was born the year of the cat, and I am a Leo… curiosity, and all that…

What is a Tim Tam?

A really good, chocolate cover ‘biscuit’ (cookie for those of us who speak American)...made in Australia.  They are rather popular there…and in a few other places, nearby.  They are available here, in the US, at Target stores…usually only over the winter months.
