Generate physically based rendering materials for 3D objects Produces shaders for physically based rendering ( PBR ) that automatically adapt to texture inputs and the number of active lights. Image based lighting ( IBL ) effects are facilitated via the environment_texture input. Cycling '74 glcore Jitter messages / (texture/matrix) albedo / diffuse TEXT_HERE normal TEXT_HERE roughness TEXT_HERE metallic TEXT_HERE ambient occlusion TEXT_HERE height TEXT_HERE emission TEXT_HERE environment TEXT_HERE connect to 3d objects to set material attribute to this TEXT_HERE dumpout TEXT_HERE Set albedo / diffuse texture Sets the texture to use for the albedo map. The albedo texture, like a standard diffuse texture, sets the base color for rendering (or the base reflectivity if the textured object is metallic). Unlike a standard diffuse texture, albedo textures in PBR rendering typically have no directional lighting or ambient occlusion. Set ambient occlusion texture Sets the texture to use for the ambient occlusion map. Ambient occlusion textures are used to add additional detail to shadowy parts of a surface and are optional. Clear the input's image map Sending the clear message to jit.gl.pbr will clear the image map at the corresponding input. Set emission texture Sets the texture to use for the emission map. The emission map determines the color of light that is emitted by the object surface. In the final rendered image, the emissive lighting (emission_texture * mat_emission) color is added to the calculated lighting color. Set environment texture Sets the texture to use for the environment map. The environment map is used for calculating reflections using Image based lighting ( IBL ) effects. These are usually .env files and the same texture is read into a jit.gl.cubemap rendered via jit.gl.skybox, however, any texture can be used. Get parameter default value TEXT_HERE Get list of parameter names TEXT_HERE Get parameter type TEXT_HERE Get the parameter value Get the parameter value Set heightmap texture Set the texture to use for the heightmap. The heightmap stores the height data for an object. Each pixel stores a height value that represents the height distance perpendicular to the face of the object surface. Set metallic texture Sets the texture to use for the metallic map. Metallic textures determine the reflectivity of the textured object and support grayscale maps, where 0 represents no metalness (no reflective light color is added to the albedo) and 1 full metalness (only reflective light is displayed). The metallic_texture is multiplied by the metalness attribute to calculate final reflectivity. Set normals texture Sets the texture to use for the normals map. The normals map determines the angles of reflection for the mapped object's surface to be used when calculating lighting. Set pbr material parameter value TEXT_HERE Set roughness texture Sets the texture to use for the roughness map. The roughness affects the quality of reflections on a surface. Low roughness results in crisp and clear reflections, while higher roughness diffuses them, resulting in wider and blurrier reflections. Overall roughness is determined by multiplying the roughness roughness attribute by the roughness texture.

Enabling will convert the rendered output from linear color space to non-linear sRGB color space. Users should leave enabled unless applying gamma correction at a later stage in the pipeline, e.g. via jit.gl.pass. Height scaling factor when parallax enabled (default = 1) TEXT_HERE Heightmap Mode TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Set metalness amount (default = 0.) Determines the metallic value in the material calculation (default = 0.). Fully metallic materials leave only reflected or specular light and show no diffuse (albedo) colors. If a metallic_texture map is sent then metalness should be set to 1 for expected output. The instance name (default = UID) TEXT_HERE Override jit.gl object color material attributes TEXT_HERE Enable parallax height mapping (default = 0) Enable parallax height mapping (default = 0). Requires a height map image sent to the heightmap_texture input. When enabled both normals and ambient occlusion maps are ignored and tex_gen mode is disabled. Parallax heightmap shadowing values (default = 0.3 0.1) Parallax heightmap shadowing values (default = 0.3 0.1). The first value sets the amount of self-shadowing (when self_shadow is enabled) and the second value sets the amount of ambient occlusion shadowing. Enable reflections from the environment map (default = 1) Enable reflections from the environment map (default = 1). When enabled a specular reflections map is generated from the environment map input and the shader will use specular reflection calculations when rendering. Set roughness amount (default = 0.3) Determines the microsurface's roughness in the bidirectional reflective distribution function ( BRDF ) (default = 0.3). Perfectly smooth surfaces have a roughness of 0. If a roughness_texture map is sent then roughness should be set to 1 for expected output. Enables self shadowing when parallax enabled (default = 0) Enables self shadowing when parallax enabled (default = 0). Shadow eps Shadow epsilon (eps) modifies the shape of shadows, and corrects self-shadowing error (default = 0.2). This value is used when the bound object is a shadow-receiver. Shadow hardness Adjust shadow hardness (default = 0.7). This value is used when the bound object is a shadow-receiver. Shadow radius Adjust shadow blur radius (default = 0.3). This value is used when the bound object is a shadow-receiver. Shadow softness Adjust shadow softness (default = 0.3). Overwrites shadow_radius and shadow_hard attributes. This value is used when the bound object is a shadow-receiver.

When enabled texture coordinates are generated from world space projections of two planes (biplanar) or three planes (triplanar). No generation TEXT_HERE Generate from two planes of projection TEXT_HERE Generate from three planes of projection TEXT_HERE Texture repeat amounts (default = 1 1) Horizontal and vertical multipliers of texture coordinates (default = 1 1). Values greater than 1 cause repetitions when texture mapping. The attribute effects both tex_gen mode none and triplanar. Triplanar blending amount (default = 0.7) The triplanar blending amount adjusts the fade between planar projections when tex_gen mode is triplanar (default = 0.7). Type TEXT_HERE This object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it. Additionally it can reference the name of a jit.gl.node sub-context. This value may also be set via the OB3D drawto attribute. If no argument is present, the object is implicitly added to the first valid drawing context or sub-context found in the current patch or by searching up the patcher hierarchy.
