Why does my low quality png import incorrectly?

8978-raycar52.png

I try to import this image to ue4 and it does really weird stuff

As you can see i’ve changed a few settings but it still looks weird, and if I import a psd it works just fine with the same settings changed (filter: nearest, compress without alpha and compression setting: TC vector displacementmap)

Hey raycar5 -

Can you post a screenshot of the image imported correctly for me to compare to? I am having a hard time understanding exactly what your issue is.

Thank You

This is the image properly imported imported as a psd (white is alpha):

Thanks for trying to help ^^

Thank you raycar5. I have tried to reproduce this with a similar PNG but I think I am missing a step you are taking. How are you saving the PNG from Photoshop?

Thanks

save as > png > no compression non interlaced

Hi Raycar5 -

If you go under view in the Texture Editor of the imported PNG, turn on Alpha and it will render black over the stretched pixels. I believe that this is artifact of the compression process for the asset and should not effect any use of the texture. The engine rounds 4 pixels to the nearest color in the compression process, so you white is rounded to match your yellow.

Thank You

YES that worked
Thanks ^^
