Is there a way to prevent a single object from casting shadows? If I shut down "Cast Shadows" on the light source then all shadows will be lost. That is not what I want. I want to be able to prevent a single object from casting shadows.

A use case may be a laser. If I were to use a cylinder to model my laser, and that laser was positioned between a wall and a light source it will cast a shadow on the wall, but it should not cast a shadow.

    $\begingroup$ There are some valid questions in there, but they should be submitted separately. The rest of this does not belong as a question on stack exchange, it's more suitable to a discussion forum like blenderartists. $\endgroup$

    $\begingroup$ You just need to split up your questions, check other questions here that are voted up, if you want to discuss many topics at once and general workflow issues, use a forum. $\endgroup$

Objects not casting shadows? easy, un-tick the shadow box.

In Cycles 2.79+, Ray Visibility was renamed to Cycles Settings.

As for the lighting, Cycles simulates the physical behaviour of light with some reasonable accuracy. All techniques used in real photography can be applied to lighting setups in cycles, The video also discusses the composite of various render passes, I think you'll find they are all possible in Blender. Be specific about what you want to know and you will get accurate answers.

  • $\begingroup$ Thanks, one less thing to worry about. Ok, next thing. What about making a light cast only specular like in the video? Is that the Glossy option? $\endgroup$

    $\begingroup$ @00Ghz you can ask several questions here so feel free to ask, each post should have only one question to limit the scope. $\endgroup$

  • $\begingroup$ In Blender 2.79, this is under Material >> Shadow >> Cast $\endgroup$

In v2.83 I found the setting as follows:

Selecting the object and then, in the sidebar, going to Object Properties->Visibility->Ray Visibility->Shadow (check/uncheck).

Note: Changing the material properties did not remove the shadow cast by the object.

For 2.8 and for rendering I found selecting the shadow mode to None to be working. It's under material settings.

    $\begingroup$ This is how to do it in Eevee. The other solutions are for Cycles. $\endgroup$

Cycles, Blender 2.79

Select the object, and in Properties / Object / Cycles Settings, disable Shadow.

    $\begingroup$ @Leander "Ray Visibility" in the other answer looks like a section that doesn't exist in 2.79 $\endgroup$

  • $\begingroup$ The comment by Regular Joe made me think the answer might be something different because materials were mentioned. Thus decided to make new answer. I'd suggest updating screenshot or splitting your answer into two for different version/(ranges?) with # headers. cheers $\endgroup$
