Scaling objects smoothly

[Mantoid]

I have a lot of objects in my game which need to scale up and down.
I've been using the scale feature but it pixelates objects as they get larger and they end up looking quite ugly! Is there a way of scaling things with anti-aliasing so that the pixelation is smoothed out a bit? I think it's possible to scale something downwards like this at the moment using some of the shaders, but scaling smoothly upwards beyond the object's size boundaries seems to be impossible.

I guess that this means that there is no texture filtering being done on upscaling. I don't think this can be controlled from a pixel shader. It could be emulated, but it would be much better just to get texture filtering for upscaling turned on.

Though TBH, with filtering on upscaling you're just trading pixelation for blurriness.

[Mantoid]

Indeed, but blurriness is much less of an eyesore than pixelation, especially against a smooth looking background.

Yea, especially with poofy things like smoke puffs and stuff.

But I can't think of why you'd be having this pixelation in HWA mode, the graphics card won't pixelate it unless that's it's only option.
