useMaterial

The useMaterial hook allows you to create and manage a PlayCanvas StandardMaterial instance. Create a material with the hook and apply it to a <Render/> component.

Usage

You can create a material with the hook and apply it to a <Render/> component and update material properties dynamically.

Parameters

The hooks accepts an object with the following properties that closely match those of the StandardMaterial class.

Parameters

NameTypeDefault
userAttributes?
Map<any, any>
-
onUpdateShader?
UpdateShaderCallback | undefined
A custom function that will be called after all shader generator properties are collected and before shader code is generated. This function will receive an object with shader generator settings (based on current material and scene properties), that you can change and then return. Returned value will be used instead. This is mostly useful when rendering the same set of objects, but with different shader variations based on the same material. For example, you may wish to render a depth or normal pass using textures assigned to the material, a reflection pass with simpler shaders and so on. These properties are split into two sections, generic standard material options and lit options. Properties of the standard material options are StandardMaterialOptions and the options for the lit options are LitShaderOptions.

greenWrite?
boolean
Sets whether the green channel is written to the color buffer. If true, the red component of fragments generated by the shader of this material is written to the color buffer of the currently active render target. If false, the green component will not be written. Defaults to true. Gets whether the green channel is written to the color buffer.
-
blueWrite?
boolean
Sets whether the blue channel is written to the color buffer. If true, the red component of fragments generated by the shader of this material is written to the color buffer of the currently active render target. If false, the blue component will not be written. Defaults to true. Gets whether the blue channel is written to the color buffer.
-
alphaWrite?
boolean
Sets whether the alpha channel is written to the color buffer. If true, the red component of fragments generated by the shader of this material is written to the color buffer of the currently active render target. If false, the alpha component will not be written. Defaults to true. Gets whether the alpha channel is written to the color buffer.
-
blendState?
BlendState
Sets the blend state for this material. Controls how fragment shader outputs are blended when being written to the currently active render target. This overwrites blending type set using Material#blendType , and offers more control over blending. Gets the blend state for this material.
-
blendType?
number
Sets the blend mode for this material. Controls how fragment shader outputs are blended when being written to the currently active render target. Can be: - BLEND_SUBTRACTIVE: Subtract the color of the source fragment from the destination fragment and write the result to the frame buffer. - BLEND_ADDITIVE: Add the color of the source fragment to the destination fragment and write the result to the frame buffer. - BLEND_NORMAL: Enable simple translucency for materials such as glass. This is equivalent to enabling a source blend mode of BLENDMODE_SRC_ALPHA and a destination blend mode of BLENDMODE_ONE_MINUS_SRC_ALPHA. - BLEND_NONE: Disable blending. - BLEND_PREMULTIPLIED: Similar to BLEND_NORMAL expect the source fragment is assumed to have already been multiplied by the source alpha value. - BLEND_MULTIPLICATIVE: Multiply the color of the source fragment by the color of the destination fragment and write the result to the frame buffer. - BLEND_ADDITIVEALPHA: Same as BLEND_ADDITIVE except the source RGB is multiplied by the source alpha. - BLEND_MULTIPLICATIVE2X: Multiplies colors and doubles the result. - BLEND_SCREEN: Softer version of additive. - BLEND_MIN: Minimum color. - BLEND_MAX: Maximum color. Defaults to BLEND_NONE. Gets the blend mode for this material.
-
depthState?
DepthState
Sets the depth state. Note that this can also be done by using Material#depthTest , Material#depthFunc and Material#depthWrite . Gets the depth state.
-
depthTest?
boolean
Sets whether depth testing is enabled. If true, fragments generated by the shader of this material are only written to the current render target if they pass the depth test. If false, fragments generated by the shader of this material are written to the current render target regardless of what is in the depth buffer. Defaults to true. Gets whether depth testing is enabled.
-
depthFunc?
number
Sets the depth test function. Controls how the depth of new fragments is compared against the current depth contained in the depth buffer. Can be: - FUNC_NEVER: don't draw - FUNC_LESS: draw if new depth < depth buffer - FUNC_EQUAL: draw if new depth == depth buffer - FUNC_LESSEQUAL: draw if new depth <= depth buffer - FUNC_GREATER: draw if new depth > depth buffer - FUNC_NOTEQUAL: draw if new depth != depth buffer - FUNC_GREATEREQUAL: draw if new depth >= depth buffer - FUNC_ALWAYS: always draw Defaults to FUNC_LESSEQUAL. Gets the depth test function.
-
depthWrite?
boolean
Sets whether depth writing is enabled. If true, fragments generated by the shader of this material write a depth value to the depth buffer of the currently active render target. If false, no depth value is written. Defaults to true. Gets whether depth writing is enabled.

Advanced Properties

The StandardMaterial accepts many different properties which can be found here.

import { useMaterial } from '@playcanvas/react/hooks'

function AdvancedMaterial() {
const material = useMaterial({
diffuse: 'purple',
opacity: 0.9,
metalness: 0.3,
roughness: 0.4,
emissive: 'yellow',
emissiveIntensity: 0.2,
specular: 'white',
shininess: 50,
reflectivity: 0.8,
clearCoat: 0.5,
clearCoatRoughness: 0.1
})

return <Render type="box" material={material} />
}

Material with Textures

You can use textures with the material by loading them with the useTexture hook.

import { useMaterial } from '@playcanvas/react/hooks'
import { useTexture } from '@playcanvas/react/hooks'

function TexturedMaterialExample() {
const { asset: diffuseMap } = useTexture('diffuse.jpg')
const { asset: normalMap } = useTexture('normal.jpg')
const { asset: roughnessMap } = useTexture('roughness.jpg')

const material = useMaterial({
diffuseMap: diffuseMap?.resource,
normalMap: normalMap?.resource,
roughnessMap: roughnessMap?.resource,
diffuse: 'white',
metalness: 0.5,
roughness: 0.5
})

return <Render type="box" material={material} />
}

Material Sharing

You can easily share materials between multiple render components:

import { useMaterial } from '@playcanvas/react/hooks'

function SharedMaterial() {
const material = useMaterial({
diffuse: 'orange',
metalness: 0.7,
roughness: 0.3
})

return (
<div>
<Render type="box" material={material} />
<Render type="sphere" material={material} />
<Render type="cylinder" material={material} />
</div>
)
}
