Hi all,

i have created a 3DS object from a mesh obtained from a boolean subtraction in bryce, then i have imported it in a project and i am not able to see his shadow on the wall.

I am using spotlight or parallel lights with the same result.

The material is not transparent.

Solid when boolean rendering is checked.

Any hint?

thank you in advance guys!

    Have you got sun / moon shadows enabled on your Sky setup ?

    No, i set it to disabled cause i am rendering an indoor scene.
    Now i got a mesh with an hole a wall and a spotlight.

    Thank you four your kind and quick answer.

    You can disable the sunlight, but you do need it to be casting shadows, so make sure you have a percentage in the sun / moon shadows in the sky lab.

    Maybe your mesh is set to not cast shadows?

    To check;
    Select the mesh and go into the material editor.

    A. Click the triangle indicated by the red circle.
    B. Make sure there is a tick next to the "Cast Shadows" option.

    The other possibility is that your wall is not set to receive shadows.
    In that instance, follow the same instructions above but selecting the wall and checking that "Receive Shadows" has a tick.

    Hope this helps.

    Unluckily i am still experiencing the issue.
    Materials looks OK (cast shadows is flagged).
    These are my Sky Lab settings:

    Ouch... please forgive me, i was focused on objects and materials. Here we go with the Sky Lab settings.

    You may want to ramp that shadow percentage up a bit. See if that makes any difference.

    BTW, just a thought do you have any ambience dialled in for the mat on the wall. Ambience can soften or even disappear shadows.

    The tutorial I did only the other day might help here since it covers the three main causes of shadow loss caused by lighting.

    Ambience settings
    Global shadow intensity
    and Sky dome colour

    If Sun/Moon Shadows are lower than 100, the object gets increasingly transparent to light and thus brightens the shadows. This control is a global control. If set to 0, neither lights nor IBL cast shadows, no matter how high the shadow intensity is set. Best set it to max and control the shadow intensity for the light sources separately.

    Yeah, I think they need to rename the control. Global shadows makes more sense.

    I'd say it's also the "Shadow Ambience" setting in the light lab - which I always keep at zero. It'll really wash out shadows.
