Hide shadow object?

[sonnguyen]

Hello mates, Is it impossible to hide shadow of an object cast on other?

I don't get what You mean? You want to have an object that casts a shadow but is not visible like the sphere in the image or You want to have an object that doesn't cast any shadow?
for the first option, You may disable view for the camera, and for the second scenario, You may create a transparent shadow by setup its color to white.

I want the second option. Thank you so much.
