Cinerender - Create a surface that does not cast shadows

Anonymous — Thu, 11 May 2023 09:43:31 GMT

Hello!

I need to render a semi transparent object that does not cast any shadows.

I've looked for an option to disable shadowcasting of objects/materials, but I can't find it. Please don't tell me it's not possible in this render...

Hi.

What kind of object? Object object or construction tool object (wall, slab, etc)? How "semi transparent" and to what purpose? (maybe there are other ways)

If it is an object, and it doesn't have to option to disable shadows, just edit the 3D script. Select the object and File->Libraries and objects->open object. In the 3D script, add:


SHADOW OFF

You can also create a new parameter, boolean type, and name it something like "showShadow". Then you could change the script to:


IF showShadow THEN
	SHADOW ON
ELSE
	SHADOW OFF
ENDIF

and you have a parameter to control it in the object settings.

If the object is a wall or a slab, I don't think there's a way to turn off shadows, and surfaces won't give you enough visibility of a transparent object without any shadow. But you can still save it as an object and use the previous option.

Best regards.

Thank you!! It works, the shadow is gone!

I use morph surfaces to create simple diagram graphics in the image. It's not ideal to save them as objects, but at least it solves the problem

Morphs have an option to remove shadow casting.

Best regards.
