Hi, I updated to 1.1 today and converted an old scene to test the new corona bitmap speed increase. Immediately I noticed a lot of my textures were blurry, basically unusable. I'm pretty sure it has to do with the ratio of width/height of the texture (square size texture render fine but anything more elongated gets very blurry the more elongated)

I created an exaggerated example for you to test and I think they clearly show something is odd. I'm using corona 1.1.1
I do not mess with the blur setting at all as I never have need to before. Included testing file is saved max 2015 file.


-in the attached jpg the first bar is a texture 2000x50 pixels using standard max bitmap

-the second bar is the same texture using new corona bitmap

-the third bar is another elongated sample using corona bitmap, below it are two square planes the one on the left is is using a 50x50 pixel map as you can see its much less blurry (showing square texture render fine), the one to the right of that is using a 2000x50 pixel map with an adjusted uvw modifier just to test to see if the scale of an object is affecting everything, still blurry.

Maybe I am missing a setting that will fix this, otherwise I hope this is realized as a bug and can be fixed (I hope no one comes in chiming I shouldn't be using non-square textures, I do a lot of arch vis for trade show booths and so stuff like banners and video walls use non square ratios for graphics and it would be a big pain to resize them into square formats.

Thank you

Hey guys,

thanks for the data provided. There was a bug in filtering. The fix will be available in the nearest release.

But if you set Filtering blur value to zero, problem disappears...
