Unigine::Material Class

Header: #include <UnigineMaterial.h>

This class is used to create materials, which are assigned to each node (or each surface of the object) and define how they look like. They implement the shaders and control what options, states, parameters of different types and textures are used to render the node during the rendering passes.

The materials are referenced via GUID. Only the manual materials can be referenced via name.

The material name (taken from the file name) specifies how the material will be displayed in Materials Editor (the materials hierarchy, the nodes surface editor).

Namespaces#


Materials can be separated into different namespaces to avoid engine and user materials name collision. Default engine and editor materials have their own namespaces (Unigine and Editor respectively). For example, Unigine::mesh_base or Editor::brush_draw_post.

You can create custom namespaces for your materials. The Material::getNamespaceName() method returns the namespace of a material, if it was assigned to one.

Getting Parameter And Texture Names#

Internal names of the material's textures and parameters are displayed in UnigineEditor tooltips, clicking on the name of the parameter/texture (LMB, once) copies an internal name for it to the clipboard, which allows to easily paste it to the code.

Usage Examples#

Changing Textures#

The first example describes how to inherit a material from a base one, change material's texture and set texture flags for it. We inherit a new material my_mesh_base_0.mat from the mesh_base material, assign it to the default material ball object, change its albedo texture and set the FILTER_POINT flag for it.

Add the following code to the AppWorldLogic.cpp file.

Source code (C++)
// AppWorldLogic.cpp
#include "AppWorldLogic.h"
#include <UnigineMaterials.h>
#include <UnigineObjects.h>
#include <UnigineWorld.h>

using namespace Unigine;

/* .. */

int AppWorldLogic::init()
{
	// pointer to material to be inherited from mesh_base and customized
	MaterialPtr m;

	// finding the mesh_base material
	MaterialPtr mesh_base_mat = Materials::findManualMaterial("Unigine::mesh_base");
	if (mesh_base_mat) {
		// inheriting a new material from the mesh_base
		m = mesh_base_mat->inherit();
		
		// check if our material is editable and perform modifications
		if (m->isEditable()) {
			Log::message("Material (%s) is editable.\n", m->getPath());

			// get the number of the albedo texture of the material
			int num = m->findTexture("albedo");

			// change albedo texture of the material to core/textures/common/checker_d.dds
			ImagePtr image = Image::create("core/textures/common/checker_d.dds");
			m->setTextureImage(num, image);

			// get current flags, check if point filtering is enabled and display the result in the console
			int flags = m->getTextureSamplerFlags(num);
			Log::message("Flags for %s texture (%d):%d \n", m->getTextureName(num), num, flags);
			Log::message("FILTER_POINT %s\n", (flags & Texture::FILTER_POINT) ? "enabled" : "disabled");

			// set the FILTER_POINT flag
			m->setTextureSamplerFlags(num, Texture::FILTER_POINT);

			// get the flags, check if point filtering is enabled and display the result in the console
			int flagsSet = m->getTextureSamplerFlags(num);
			Log::message("Flags for %s texture (%d):%d \n", m->getTextureName(num), num, flagsSet);
			Log::message("FILTER_POINT %s\n", (flagsSet & Texture::FILTER_POINT) ? "enabled" : "disabled");
		}

		// saving the material asset to the specified path 
		if (!Materials::findMaterialByPath("materials/my_mesh_base_0.mat"))
			m->createMaterialFile("materials/my_mesh_base_0.mat");

		// getting the material_ball object and assigning the material_ball_0 material to it
		if(ObjectMeshStaticPtr material_ball = checked_ptr_cast<ObjectMeshStatic>(World::getNodeByName("material_ball")))
			material_ball->setMaterialPath("materials/my_mesh_base_0.mat", "*");
	}
	return 1;
}

/* .. */

As a result you'll see that albedo texture of the material ball object has changed and the following result is displayed in the console:

Output
Material (my_mesh_base_0) is editable.
Flags for albedo texture (1):2048000
FILTER_POINT disabled
Flags for albedo texture (1):4096
FILTER_POINT enabled

Changing States and Parameters#

The second example illustrates how to inherit a material from the mesh_base and change two parameters affecting the look of reflections.

Add the following code to the AppWorldLogic.cpp file.

Source code (C++)
// AppWorldLogic.cpp

#include "AppWorldLogic.h"
#include <UnigineMaterials.h>
#include <UnigineWorld.h>
#include <UnigineRender.h>

using namespace Unigine;

/* .. */

int AppWorldLogic::init() {

	// find the mesh_base material
	MaterialPtr mesh_base = Materials::findManualMaterial("Unigine::mesh_base");
	// inherit a new material from it and assign the path to asset to be created on save() call:
	MaterialPtr reflector_material = mesh_base->inherit();

	// set metallness and roughness parameters to make the surface look like a mirror
	// by the name of the parameter
	reflector_material->setParameterFloat("metalness", 1.0f);
	// or by its id, which is the same
	reflector_material->setParameterFloat(reflector_material->findParameter("roughness"), 0.0f);

	// save the material asset to planar_reflector.mat file in the data project folder
	reflector_material->createMaterialFile("planar_reflector.mat");

	// assign the mesh_base material to the material ball by its path
	ObjectMeshStaticPtr material_ball = checked_ptr_cast<ObjectMeshStatic>(World::getNodeByName("material_ball"));
	material_ball->setMaterialPath("core/materials/base/objects/mesh/mesh_base.basemat", "*");
	// assign new mirror material to the ground object
	ObjectMeshDynamicPtr ground = checked_ptr_cast<ObjectMeshDynamic>(World::getNodeByName("ground"));
	ground->setMaterial(reflector_material, "*");

	return 1;
}
