i have a TextureRenderer which i'm using for a sort of "magnifying glass" widget in my game's HUD. i have it working fine. except i can't get the smoothest mipmap settings to work–mipmap set to MM_LINEAR_LINEAR and filter set to FM_LINEAR. it just shows a random image and then doesn't update w/ my render cycle.
it does work if i set the mipmap setting to MM_LINEAR. but then the image isn't properly anti-aliased. it's pixelated a little and looks low-resolution.
any suggestions on how to get a fully anti-aliased image via TextureRenderer?
texturerenderer = display.createTextureRenderer(resolution, resolution, TextureRenderer.RENDER_TEXTURE_2D);
tScreen = new Texture();
// tScreen.setMipmapState(Texture.MM_LINEAR_LINEAR); //this setting doesn't work
tScreen.setMipmapState(Texture.MM_LINEAR); //this setting works
tsScreen = display.getRenderer().createTextureState();
