Thank you for writing Import Images As Planes. I've searched and worked for days trying to find a solution to the problem below. A solution is critical to my work. Would you please send a short reply indicating how I can know when a solution is available? Please reply to: coutwin@newstuff.com

iMac running OS X 10.14.1
AMD Radeon R9 M390 2048 MB graphics card

Blender Version 2.79b (2.79b 2018-03-22 Blender Foundation)

Broken: Import Images As Planes

An unexpected thin, white, broken line at the top of the plane.

Steps To Reproduce Error:

Open Blender preferences to confirm Import-Export: Import Images as Planes is active.
Delete default cube and snap the cursor to the center of the viewport.
Add Images as Planes.
After the file selection view appears, reset Operator Presets in the left sidebar to restore defaults.
Select a PNG file.
See the plane at the viewport’s center and check Texture Solid under Shading in the tools.
Zoom in to enlarge the plane.
Change the viewport to display Right Ortho.
Deselect the plane and zoom in to see a thin, white, broken line at the top of the plane.
Discover the Blender Stack Exchange solution of selecting Clip rather than Repeat in Textures/ImageMapping will not cause the line to disappear.

@cfromns Please embed the image into the .blend file, otherwise we cannot see anything (besides a nice pink square)…

Thank you for your reply. Please pardon my error. This is my first time at this. In reply, I opened the file, selected File/External Data/Pack All Into .blend, and saved the file.

Additionally, you may find the following Blender Stack Exchange question of interest, as it displays the problem I'm having too. Notice the thin white lines above the leaves of grass.

Thank you very much for your help. I hope I've done it correctly this time.

OK, so, this has nothing to do with that add-on in particular.

It seems to be a limitation of old GPU/3DView code in 2.7x, which always repeat textures (when rendered, the expected clipping does happen properly).

Checked in 2.8, new EEVEE 3DView rendering does respect the clipping/extend/repeat parameter.

So thanks for the report, but that's basically old limitation of 2.7x series, which has been fixed in new 2.8 one.

When I export a .dae file using 2.7x, the problem line appears using a new iPad 6 in the iOS 12.1 application I'm writing. Are there any 2.7x settings which will prevent a .dae file from containing the line?

I haven't used 2.8, because the Blender site indicates it's not for production. Will 2.8 solve the export .dae problem line? Any suggestions would be greatly appreciated.

You can simply slightly shrink the UV map of the plane (to 0.999 of its original size e.g.), should be enough to remove that artifact.

Another solution could be to ensure your texture have a 1px margin of fully transparent pixels.
