Unused bindings throw error #4577
Description
struct Uniforms { resolution: vec2f, time: f32 };
@binding(0) @group(0) var<uniform> U : Uniforms;
@binding(1) @group(0) var mySampler: sampler;
@binding(2) @group(0) var myTexture: texture_2d<f32>;
struct out{
position: vec4f,
color: vec3f
}
@fragment
fn main(@builtin(position) fragCoord : vec4f,
@location(0) color: vec3f) -> @location(0) vec4<f32>
{
var uv = fragCoord.xy/U.resolution ;//* 2. -1.;
//uv*= vec2f(1, -1);
var col:vec4f = textureSample(myTexture,mySampler,uv);
return vec4<f32>(color,1.);
}Everything works fine until I comment this line
var col:vec4f = textureSample(myTexture,mySampler,uv);I receive this error
Number of entries (3) did not match the number of entries (1) specified in [BindGroupLayout].
Expected layout: [{ binding: 0, visibility: ShaderStage::(Vertex|Fragment), buffer: { type: BufferBindingType::Uniform, hasDynamicOffset: 0, minBindingSize: 16 } }]
- While validating [BindGroupDescriptor] against [BindGroupLayout]
- While calling [Device].CreateBindGroup([BindGroupDescriptor]).1
I'm getting an error for not using these bindings, am I forced to use them?
