I want to achieve a simple ‘additive’ shader effect for my objects in Mantra, but as I'm quite new to shading and rendering in Houdini I don't know where to start.

Attached is an image showcasing the desired effect.

Setting Of to zero will prevent the surface from occluding. For raytracing engines, you may want to disable ‘stochastic transparency’ to prevent the image being full of holes.

surface ghost(
    vector color = {0.0, 0.2, 0.0};
    export vector Ce = 0;
)
{
    Cf = Ce = color;
    Of = 0;
}
