[BUG] 1.1.1 coronabitmap blurriness and image width/height ratio

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

Something is wrong indeed.

Same problem here (with a long road texture)
I must to use 3ds max bitmap.

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…

this is already fixed in the latest daily build - you can try it
