[LayaAir3]laya3.2.4可以将相机renderTexture渲染到一张texture2d上么？
/**创建一个拍摄一帧 */
CreateCaptureFrame(sp:Laya.Sprite,cameraSet:(camera:Laya.Camera)=>void,cb:(umd:UIModelData)=>void){
const camera = GameMgr.uiModelMgr.CreateCamera()
cameraSet && cameraSet(camera)
GameMgr.timer.frameOnce(2,this,()=>{
const arr = new Uint8Array(camera.renderTarget.width * camera.renderTarget.height * 4)
camera.renderTarget.getDataAsync(0,0,camera.renderTarget.width,camera.renderTarget.height,arr).then((buffer)=>{
console.log(buffer)
const tex2d = new Laya.Texture2D(512,512,Laya.TextureFormat.R8G8B8A8,true,false)
tex2d.setPixelsData(buffer,false,false)
const data:UIModelData = {
camera,
sp,
tex2d:tex2d,
}
camera.active = false
sp.texture = new Laya.Texture(tex2d)
this.createDatas.push(data)
cb && cb(data)
})
})
}我之前让相机拍摄一帧，并不想持续拍摄，这是我尝试实现的代码，但是没有显示

this.button.on(Laya.Event.CLICK, this, this.onButtonClick);
//加载渲染纹理，加载成功后得到的是一个Laya.Texture对象
Laya.loader.load("resources/RenderTexture.rendertexture").then((res) => {
this.texture = res;
})
}
onButtonClick() {
this.uint8Array = this.texture.getTexturePixels(0, 0, 256, 256);
this.texture2D.setPixelsData(this.uint8Array, false, false);
this.owner.texture = new Laya.Texture(this.texture2D);
}
}

}但是捕获到的图片发白，不知道怎么回事
