Need to make a correction. I said wrong, the ray trace shadow it does not shin threw.

I set the map size from 256 to 1024 the shadow is still hard.

What did I do wrong ?

There is no shadowmap used in raytraced mode. So the size doesn't matter :)
Set "shadow blur radius" to a higher value to get softer shadows.

I do not no how to check normals in Poser,yet.

I did not model it it's the Angle of light skirt I got from DAZ.

the mesh is single sided.

Use  "Grouping Tool".

I exported the mesh

imported it back the light did not shin threw.

So the same skirt with "depth map shadow"

if its a figure the light shines threw

but

if it's a object the light does not shin threw.

Shouldn't make a difference wether a geometry is defined as a figure or as an object (a figure is nothing more then some objects glued together with a CR2 file).

But maybe you set some options while ex-/importing the mesh. As a result you may have loaded back something different then the mesh in the figure.
