13	\qmltype PrincipledMaterial
14	\inherits Material
15	\inqmlmodule QtQuick3D
16	\brief Lets you define a material for 3D items using the metal/roughness workflow.
17
18	Before a Model can be rendered in a scene, it must have at least one material attached
19	to it that describes how the mesh should be shaded. The PrincipledMaterial is a PBR
20	metal/roughness material that aims at being an easy to use material with a minimal
21	set of parameters.
22	In addition to having few parameters, all input values are strictly normalized
23	between 0 and 1 and have sensible defaults, meaning even without changing any values,
24	the material can be used to shader a model. For an introduction on how the
25	different properties of the principled material affects how a model is shaded,
26	see the \l{Qt Quick 3D - Principled Material Example}{Principled Material example}.
27
28	\section1 Metal/Roughness workflow
29
30	The Principled material is what's known as a metal/roughness material, in essence
31	that means the main characteristics of the material is controlled through
32	the \l {PrincipledMaterial::metalnessMap} {metallness}, \l {PrincipledMaterial::roughnessMap} {roughness},
33	and the \l {PrincipledMaterial::baseColorMap} {base color} property.
34
35	\section2 Metalness
36
37	Real world materials are put into two main categories, metals and dielectrics (non-metals).
38	In the Principled material, the category a material belongs to is decided by the
39	\c metalness value. Setting the \c metalness value to 0, means the material is a dialectric,
40	while everything above 0 is a considered to be a metal. In reality metals will have
41	a \c metalness value of 1, but values between 0 and 1 are possible, and usually used
42	for metals with reduced reflectance. For example, to render corrosion, or similar,
43	on a material, the \c metalness of the material should be reduced to give the output
44	properties more similar to a dielectric material.
45	Since the \c metalness value affects the reflectance of the material it might be tempting to
46	use the metalness to adjust glossiness, but consider what type of material you want
47	to describe first. Increasing the \c metalness value to give a dielectric material
48	a more polished look, will introduce properties that are not accurate for a dielectric
49	material, so consider if it would be more appropriate to adjust, for example,
50	the \c roughness value instead.
51
52	\section2 Roughness
53
54	The \c roughness of a material describes the condition of an object's surface.
55	A low \c roughness value means the object has a smooth surface and therefore be more
56	reflective then a material with a higher \c roughness value.
57
58	\section2 Base color
59
60	The \l {PrincipledMaterial::baseColorMap} {base color} of a metal/roughness material
61	contains both the diffuse and the specular data, how much the base color is interpreted
62	as one or the other is primarily dictated by the \c metalness value. For example,
63	a material with a metalness value of 1, will have most of its base color interpreted
64	as specular color, while the diffuse color would be a black tint. The opposite would
65	happen for a material with a metalness value of 0. This is of course a bit simplified,
66	but gives a rough idea how the \l {PrincipledMaterial::baseColor} {base color} and
67	\c metalness value interacts. For those more familiar with a Specular/Glossiness workflow,
68	there's a clear difference here which is worth noting, namely that the color data of the
69	two materials are not directly compatible, since in a Specular/Glossiness
70	\l {DefaultMaterial} {material}, the diffuse and specular color comes from separate inputs.

84
85	When using \c PrincipledMaterial.NoLighting no lighting is calculated. This
86	mode is (predictably) very fast, and is quite effective when image maps are

102	occlude objects behind them. This default mode does not guarantee alpha
103	blending in the rendering pipeline on its own for models that use this
104	material, but rather makes the decision dependent on a number of factors:
105	if the object's and material's total opacity is \c{1.0}, there is no
106	opacity map in the material, and \l alphaMode is not set to a value that
107	enforces alpha blending, then the model is treated as opaque, meaning it is
108	rendered with depth testing and depth write enabled, together with other
109	opaque objects, with blending disabled. Otherwise the model is treated as
110	semi-transparent, and is rendered after the opaque objects, together with
111	other semi-transparent objects in a back-to-front order based on their
112	center's distance from the camera, with alpha blending enabled.
113
114	\value PrincipledMaterial.Screen Colors are blended using an inverted
115	multiply, producing a lighter result. This blend mode is order-independent;
116	if you are using semi-opaque objects and experiencing 'popping' as faces or

118	results without popping.

262	one to use needs to be decided on a case by case basis. When it comes to
263	the Texture set to the property, specularReflectionMap has an advantage,
