Matte Shadow Element 3d



This page gives an overview of the Matte Shadow Render Element and how it may be used in compositing.

  • Hi, maybe i don´t understand you. But if you only want the shadow of the character, you have to force the other objects not to cast shadows in the object properties. On the other hand you can set the aplha distribution of your mtl wrapper mat to 0.0, what means you see the rendered shadow only in the image, not in the alpha. Or you set the alpha contribution to -1, what means you can see the.

PLA filament Matte Shadow Gray 1.75 mm 1000 g for 3D printers is of superior quality, produced in The Netherlands. Real filaments guarantees that the PLA is high-quality and diameter consistent filament, giving you the best 3D printing experience. The per-object matte options in Redshift allow you to turn an object into a matte object at render time, for compositing. It overrides the materials that are currently applied to an object and is essentially meant to be a more practical alternative to the old Redshift Matte Shadow Catcher material shader.

Overview

The Matte Shadow Render Element shows areas where light doesn't reach. Compare with the Raw Shadow Render Element, which gives areas of cast shadows. While technically not part of the Beauty render elements, the Matte Shadow Render Element can be used to lighten cast shadows by adding it to the Raw Lighting Render Element. It can also be used to assist in adding 3D elements to a background image or footage in the composite.

UI Path: ||Display Render Settings button|| > Render Elements tab > Matte shadow Matte

To use render elements, select from the Available render elements column and click the Add button to add the passes you wish to generate at render time. When you render the scene, the added render elements listed in the column on the right, will also render, which can be viewed from the VFB window's channel drop-down menu.

For more information on the parameters on this dialog, see the Render Elements tab page.

Attributes

The parameters for this render element appear in the Attribute Editor under Extra V-Ray Attributes.

Matte

Enabled – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.

Deep output – Specifies whether to include this render element in deep images

Filename suffix – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.matteShadow.vrimg).

Consider for Anti-Aliasing – When enabled, anti-aliasing is used where possible.

Denoise – Enables the render element's denoising, provided the Denoiser render element is present.

This render element is not supported with V-Ray GPU rendering.

Common uses

The Matte Shadows Render Element is useful for changing the appearance of shadowed areas in compositing or image editing software. Below are examples of its use.

Shadows help place the CG elements in the world. Literally grounding it in reality. Rendering them is easy, but for more control we need to separate the shadow layer for compositing. Creating them in 3dsMax isn’t hard and here’s how to setup V-Ray to separate the necessary passes.

I’m not going to detail matching cameras to the real world in this article. In brief we need:-

  • Our CG character
  • A proxy mesh that represents the ground in the real world.
  • A V-Ray camera matched to the lens and film back of the production camera
  • Appropriate V-Ray Lights

We use the ground proxy to receive shadows cast by our CG character. This will be the shadow layer we composite into the final shot.

The VRayMtlWrapper is a great tool for creating shadow and mask passes. There are 4 settings you need to know.

  • Matte surface
  • Alpha contribution
  • Shadows
  • Affect alpha

Matte Surface

Makes the material appear as a matte, which shows the background, instead of the base material, when viewed directly. Matte objects can be used to occlude or hide other objects in the scene.

Alpha contribution

Robot with Alpha Contribution -1

Alpha contribution allows you to control how the object will appear in the alpha channel. A value of:

  • 1.0 means that the object will appear normally in the alpha channel.
  • 0.0 means that the object will not be present in the alpha channel at all.
  • -1.0 will invert the alpha of the object.

Note:

  • This material parameter does not require the object to be a matte object.
  • A matte object does not change the appearance of the alpha channel unless its Alpha contribution is setup.

Shadows

turn this on to make shadows visible on the matte surface.

Affect Alpha

Turn this on to make shadows affect the alpha contribution of the matte surface. Areas in perfect shadow will have a white alpha, while completely shadowless areas will have a black alpha.

Set up a matte material

  • Use the VRayMtlWrapper material
  • Set ‘Base material’ to ‘VRayMlt’
  • enable ‘Matte surface’
  • change ‘Alpha contribution to’ -1.0.
  • DISABLE ‘Shadows’
  • DISABLE ‘Affect alpha’

Set up the matte shadow material

  • Use the VRayMtlWrapper material
  • Set ‘Base material’ to ‘VRayMlt’
  • enable ‘Matte surface’
  • change ‘Alpha contribution to’ -1.0.
  • ENABLE ‘Shadows’
  • ENABLE‘Affect alpha’

Hiding the Subject

It’s useful to hide the subject before rendering the shadow. This prevents the edge pealing away if you blur it in post. Jodeci every moment free mp3 downloads.

To do this simply go into the object properties dialog and turn off “visible to camera.”

The VRay Shadow element is unusual. It is not, strictly speaking, a part of the image; however, it can be added to the Raw Lighting element to adjust the shadow intensity. Simply adding the two elements produces lighting as though no shadows were computed.

After Autodesk fixed its flaky initial implantation, I’ve come to love 3dsMax State sets.

In brief its worth setting up state sets for different technical passes where you are changing materials. This allows you re-render a collection of passes at the touch of a button if you have to change the animation.
