Shadows disappear when 2 elements too close

Hi there!

I have a question about shadows: I have a spotlight that cast shadows, a heightmap as a floor, and an image as a rug. I added a 3D model of a table when the table is above the floor, the shadow is clearly here, but when I put it just “on” the floor, the shadow disappears.

When it’s “on the floor”

Sorry for the double post, I am too newbie on this forum to post 2 different pictures on the same post. Weird limitation btw!

Well, as I learned along the way a lot of things can be the reason xD My first thought is this

Try playing with the bias value. It worked for me in the past with the similar problem.
