From Poser 6 to PP2014 is a HUGE step upwards in the Lights and render areas.

No wonder Poser 6 lights can give you trouble if you do not adapt them to the newer render options.

Using the same light setup, and rendering with all PP2014 options, as IDL and SSS set to ON, will wash out all your shadows.

That is why we advice to : never buy lights. They only work in the Poser version they where build for.

Carefully evaluate all render options, certainly when using newer options as IDL and SSS.

To be fair, it has been years that I rendered with more then one infinite light in a scene, all the rest coming from the IDL and bb's sphere.
Adding a light, WOULD wash out shadows.

In real life, there is only ONE sun, all the rest of our "real life" light is IDL light.

In general, you can reduce the strenght of all lights by 50% or more when rendering with IDL.
