Hi,
when you are using a render texture do yo still use SetDesignResoultion and scaling functionality of cocos2d-x?
I think it is not needed because you can render your game into render texture and scale, set position of this texture afterwards.
Is this correct?
Another question… do you use different graphic assets like iphone iphone-hd to support the different devices?
In my case, my game has an design resolution of 1024x768 but when I scale it down for iphone resolution (non retina) the tmx map looks not so well. It seems like downscaling will decrease image quality but upscaling does not.
BR,
Stefan
