texture problem - white border

Hi

The fern looks well on 3d view but when rendered there is a white border.
Can this be fixed by some material/texture setting ?

In the Texture panel, at the “Image” tab , enable “Premultiply” and it will repair this problem in the rendering.

Hi Sanctuary, I know this option but i tried it but no change :(. Could you try it with the blend I attached ?

OK, figured it out finally, weird thing, Premultiply works ONLY if I do Unpack File on the texture.

When i tried with your model, enable Premultiply fixed completely the artifact when rendering.
I have no idea why it’s not doing it for you, what version of Blender are you using ?

edit : didn’t noticed you replied again.
edit 2 : i had no need to unpack the texture from your .blend, just loading your blend, enabling premultiply then rendering showed me a clean render.

Hi, I’ve had blender 2.60.0, now installed 2.62 and works as you described. Thank you!.

People who are facing the same problem in Blender 4.1.1 as of 2024. Experienced the same thing in Blender 4.1.1. Solved by changing Alpha value to Premultiplied. See the attached screenshot.

P.S. The texture was exported as a transparent PNG from Inkscape.
