Hi All

Does anyone have any ideas on the best way to create live updating textures.
I need the texture for the model to be updated every frame if possible. My texture is 1024x1024 and after a few seconds it goes over its resource limit.

I am not quite sure why it is doing this as it is only reloading the same image every frame.

private function enterFrameHandler(evt:Event):void
{
this.bitmapTexture = new BitmapTexture(layoutBitmap.bitmapData);
this.textureMaterial = new TextureMaterial(bitmapTexture);
coffin.material = this.textureMaterial;
}

Any help would be greatly appreciated
Thanks

Try this

var bitmapData:BitmapData = bitmapTexture.bitmapData;
         bitmapData.lock();
         bitmapData.fillRect(bitmapData.rect, 0);
         //bitmapData.draw(_video, _matrix, null, null, bitmapData.rect, _smoothing);
         bitmapData.draw(simpleVideoPlayer.container);
         bitmapData.unlock();
         bitmapTexture.invalidateContent();
         
         
         view.render();

I had just solved the problem, but thanks anyway for your reply

I would assume they updated the material without creating a whole new material every frame. That was why they would be running out of memory.
See lexcuk’s solution above.

I would create a variable which keeps a reference to the material bitmapData, ready for updating.

something like….

private var updatingBmd:BitmapData;
  private var myBitmapTexture:BitmapTexture;
  private var myMaterial:TextureMaterial;
  private var contentThatUpdates:Sprite;

  private function init():void{
   updatingBmd = new BitmapData(1024,1024);
   myBitmapTexture = new BitmapTexture(updatingBmd);
   myMaterial = new TextureMaterial(mybitmapTexture);

  }

  private function redraw(evt:Event):void{
   updatingBmd.draw(contentThatUpdates);
   myBitmapTexture.invalidateContent();
  } 

Good Luck!
