What is specular map Maya?

Specular maps By mapping a texture to the Specular attribute of an object’s material, you create a specular map which lets you describe how shine appears on objects (by controlling highlight). To learn more about how you can work with highlight, see Common surface material Specular Shading attributes.

What is gloss map?

A gloss map is a texture which modulates the contribution from specular lighting, so that some points on the surface reflect less specular light than others. The texture can be a one component alpha texture or a two or four component texture with the maximum value set for the luminance or color components.

What does specular do in Maya?

Specular highlights show the places on the object where the light sources are reflected at consistent angles; reflections on an object show, among other things, light bounced from surrounding objects. Specular highlights depend directly on the view (camera), not the position of the light, like diffuse shading does.

What is specular mapping?

Specular maps are used to define the shininess/highlight on a surface. Typically a specular map is a black and white image that maps out the shininess value on an object. The whiter the pixel, the more shiny the object in that specific place on the texture (or on the texel).

What is roughness map?

Figure 31: The roughness map describes the surface irregularities that cause light diffusion. In this map, black (0.0) represents a smooth surface and white (1.0) represents a rough surface. The roughness map is the most creative map as it allows the artist to visually define the character of a surface.

Where do you put the normal map in Maya?

Double-click on the Maya 2D File Texture node, and when it appears in the Attribute Editor, load your Normal Map in the “Image” slot. In the Attribute Editor, find the “color space” setting and set that to “Raw”.

What is the difference between a bump map and a normal map?

As we already know, a bump map uses grayscale values to provide either up or down information. A normal map uses RGB information that corresponds directly with the X, Y and Z axis in 3D space.

What is specular in Arnold?

Specular is direct and indirect reflections which can be made glossy (blurred). Specular maps can be used to define a surface’s shininess and highlight colour. The higher the value of a pixel (black to white), the shinier the in game object.

How to get a gloss map in Maya?

in maya you will need to get a hlsl, or cgfx shader like kodde said in UDK Gloss is 1 of your parameter inputs, it’s just not called gloss, so just look for specular exponent.

How are gloss maps and specular maps related?

A gloss map defines the size of the specular highlight per pixel also called specular power, where as a a typical specular map defines the intensity per pixel meaning it represents the amount of light reflected. Offline / Send Message

What’s the difference between gloss and specular level?

Basically, the gloss map is the intensity of the spec map. Generally, it will make your spec have a slightly more “wet” feel to it. You use your spec to determine what areas receive specular highlights, and the gloss map to adjust how intense it is. How glossy the spec map is.

Are the gloss maps from a specular workflow generally interchangeable?

My question; In general are the gloss maps from a specular workflow generally interchangeable/sufficient as a roughness map (after inversion) for a metalness workflow or does the missing specular/reflection map contain too much needed information? Is it a case of ‘depends on the artist that made the maps’ or a more generalised thing?
