Disable shadows in Rendering

[Anonymous]

I have an animated 3D object that I need to export with alpha channel in order to use it in video production.

The problem is the shadows:

I have read online that I need to go into Object Properties and disable Cast Shadows and Receive Shadows

I did it several times, but the Render output is always the same: the object has the shadows..........

Do you notice any difference?

How can I solve? Thank you in advance...

Which renderer and lighting are you using ?  Try scanline or Quicksilver and you should be able to control shadow casting by changing object properties.  Be sure rendering control is set to By Object (not By Layer).

I'm using Scanline renderer.

Object Properties

Render Setup

Something wrong?

Your settings look good.  I assume they are applied to the two objects in the scene.  The shadow edge I circled appears to be a shadow and not simple shading.  Do you have any lights in the file (Tools, Light lister)?

Can you post the file?

Unfortunately there are no lights there.......... what's the problem here...

If you don't have any lights in your scene 3D MAx will use a 'Default light' this light doesn't have any options.

You need to place at least one light in your scene to make the system works.

Now those 'Shadows' you are pointing, are basic ambient shadows to help you to read the shape or volume of objects, without this shadows your 3D object will look flat.

IF this is what you are looking for, then place any light in your scene and in the light Advance Effects check Ambient Only.

Then your object will turn completely flat.

Thank you for the answer.

I expected that... with no light the 3D object won't look 3D anymore...

I don't want to have it flat though... is there a way to at least make the shadow "less black"?

You could use three lights and have all three set so that they do not cast shadows.   I like to set each light to a different color and then do a test render where the color indicates the contribution from each of the three lights. You can then adjust their intensity and position before setting their color to white.

What are you trying to achieve??  What type of image are you doing?

You can enable Light tracer put a white environment and add a skylight and render just like that, you'll get only environment light.

If that's the look you need, then you could do the same with Art render, or Arnold and use only Environment light, not direct light.
