    I'd like to help but I'm not sure I understand what exactly you're after. Can you link to a sample image of what you're trying to do?

    If it's only on the body, you could fake with LIE or an external 2D paint App by puting a layer over the skin if you just want a still image

    For an animation it will be trickyer

    Can be done with a spot Light and a primitive plane with a couple of easy to make textures applied to the surfaces of the plane.

    @Jaderail

    I also think that, I'm new in DAZ,I do not know exactly how to do it ... if you can explain a little better,...
    Thank you all very much for your answers and help!

    What about light gels? I honestly don't know much about them, but seems like the sort ot thing that might work here? Anyone?

    I think that's what Jaderail meant. Easy to do. If you make your own transmap you can apply it to a “plane” primitive. All you need to do is go into photoshop or similar and paint your cross or X with black and white. I think black is opaque and white is transparent - can't remember because I have two programs that do it opposite ways. Save your image as an obj or png.

    Load your plane primitive in DS from the “Create” menu > primitives.

    From there you just go to your surfaces tab (wile your plane is selected) and load your transmap into the opacity slot.

    Greetings,
    Something like this. (Images attached.)

    What I did was create a large plane (the object to put the shadow on) and a smaller one (the one to block the light). I marked the light as having raytraced shadows (because they're faster than deep shadow maps, which makes no bloody sense), and a 2% shadow softness. I moved the blocking plane to RIGHT underneath the light (as you can see) and after a test render that showed that it was blocking it, I used the Polygon Group Editor to select squares from the light-blocking plane. Once I'd built a small window in selection, I right-clicked and 'create surface from selection'. I selected that surface in the Surfaces tab, and set its opacity to 0. Voila, instant window-type shadow.

    To do it properly, I should probably make the blocking plane larger, so the light doesn't bleed past the edges, but this was just a demonstration.

    And if you hope to something like gel color effect,
    make texture with black background and ray color.

    then inverse pixel tone. in your draw tool. (Gimp photo shop ,etc)

    it make white background and inverse color mark (or tatoo etc) image.
    save it as jpg, then apply it on the filter plane opacity strongness .

    or you can simply apply the original texture with black background,
    then inverse pixel tone by DS Layer Image editor too.

    you can access LIE by Right click the texture map on surface tab.
    there is inverse option.

    how you set spot light angle, locate and resize the gel plane.
    the reflect lay size change.

    And you may need some test to get the effect which you hope.
    (more narrow slit texture make more clear effect
    in may case the letter width is too wide ,,, )

    after that make spot light as parent of the thlit gel plane.
    then you can save it as scene subset.

    If you try to use Uber Area light shader, as emitter,
    and set Primitive Cone as cover of light ,
    and make gel plane, apply texture as opacity map,
    it can work too.

    I hoped to talk about gel mesh light,
    and how to make simple mesh gel light by ds tool only,,,
    but spot light is more simple, and maybe easy to set up .
