Resource that acts as the main interface to a compute shader. Controls how GPU buffers are bound to shader inputs. It also creates and holds a set of uniform struct instances, matching those exposed by the shader. If a uniform exposed by this material is updated, all the objects rendered using this material will use that same value, unless overridden by a nap::ComputeMaterialInstance.
Unlike nap::Material, does not expose vertex attribute buffer bindings (or blend/depth modes). It is still possible to access a nap::VertexBuffer<T> in a compute shader through a nap::BufferBinding. This way, mesh data can remain static on the GPU, while being mutable in a compute shader.

Initializes the compute material. Validates and converts all the declared shader variables into instances and sets up the vertex buffer bindings.
| errorState | contains the error if initialization fails. |
Reimplemented from Object.
| ResourcePtr<ComputeShader> mShader = nullptr |
Property: 'Shader' The compute shader that this material is using.
