What is refraction of light in Maya?
Light goes through the object and bends at an angle. Example: diamond (greater angle) or water (lesser angle) See also Types of refraction (Diffuse, Specular, and Glossy).
How do you change the refractive index in Maya?
Use Arnold for Maya (mtoa) shaders
- Select your object. In the Attribute Editor, expand the Arnold section and disable Opaque.
- In the aiStandardSurface Attribute Editor or Property Editor, set Transmission > Weight to 1. Ensure that Base > Weight is set to 0.
- Set your index of refraction on the Specular > IOR attribute.
What is reflection in Maya?
The sphere is reflected in the plane. This tells Maya to raytrace any surface whose Visible in Reflections/Refractions is toggled on. These attributes are on by default for all surfaces, but raytracing only works when you turn on Raytracing in the Render Settings window.
How do you make an object transparent in Maya?
Select the object you want to modify in the Scene View. Click Item Tools tab Appearance panel. Move the Transparency slider to adjust how transparent or opaque the selected object is.
What is bump map in Maya?
Bump maps are grayscale textures you map to objects to create the illusion of surface relief (elevations and depressions) on an otherwise flat object. Bump maps just change the direction of the surface’s normals based on the bump map’s Alpha Gain value. Use bump maps to create very shallow reliefs.
What is refraction Arnold?
Transmittance filters the refraction according to the distance traveled by the refracted ray. The longer light travels inside a mesh, the more it is affected by the Transmittance color. Therefore green glass gets a deeper green as rays travel through thicker parts.
How do I turn on reflection in Maya?
How to turn on ‘Reflection’
- Double-click the ‘Move’ tool.
- Go down to ‘Reflection Settings’
- Tich the ‘Reflection’ box (and choose the right axes below it)
What is reflection in Arnold?
Nov 16, 2012. The Standard shader has a secondary layer of reflection, called simply reflection, which is perfectly sharp and mirror-like. It should only be used to replicate perfect mirrors or glass shaders. If you want blurry reflections only you should use Specular.
Does Maya render hidden objects?
The primary visibility attribute in the Render Stats allows an object to reflect and refract, but the object itself does not render. To do so, both the visible objects and the hidden objects (the objects for which you wish to show reflection and refraction) must belong to the same layer.
How do you hide a plane in Maya?
Remove or hide a background or image plane
- Select View > Camera Attribute Editor from the panel menus.
- In the Attribute Editor, in the Image Plane Attributes section, set Display Mode to None.
What is Maya scene view?
In Maya software, you visualize your scenes using view panels that let you see into the 3D world. Perspective views let you see your scene as if you were looking at it with your own eyes or through the lens of a camera. Orthographic views are parallel to the scene and offer a more objective view.
How do you add refraction to Maya Maya?
How to Add Refraction in Maya. Refraction causes the light to bend as it passes through an object. Materials refract light in different ways. The number that is assigned to a material’s refraction is called it’s Refractive Index. For instance, air has a Refractive Index of 1.0, glass is 1.6 and water is 1.3. For a complete list of materials and
How are reflection and absorption represented in Maya?
All objects have a degree of reflection and absorption. In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray, for example). These types of light, however, are not represented in Maya because they have no visual effect.
What is the refractive index of water in Maya?
For instance, air has a Refractive Index of 1.0, glass is 1.6 and water is 1.3. For a complete list of materials and their Refractive Index, see Maya help or do a web search. To render material refraction you need to enable Raytracing in the Render Options for a Maya Software render or use Mental Ray.
How are absorption, reflection and refraction of light related?
Absorption, reflection, and refraction of light. By: Help. The color of the objects we see in the natural world is a result of the way objects interact with light. When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption.
