If you want to recreate yourself with new file:

  1. Delete everything in the scene
  2. Add "bezier curve"
  3. Extrude at least 1-2 points
  4. Add "Depth" in Curve panel -- Bevel - Depth
  5. Scale some points
  6. Add any material, add wave node and plug it to color in Principled BSDF
  7. Go to render view -- everything is OK.
  8. SAVE, CLOSE BLENDER AND RELOAD
  9. After reloading file -- the material on curve is NOT displayed.

untitled.blend

That's the new file I created with steps above (because I thought initial file was broken, so tried to recreate)

@linosia In the meantime while you wait for the bug to be fixed, you can get the rendering of the curve to return by adjusting the value in the "Curve panel -- Bevel - Depth" section. This still has the issue of the curve not being visible after saving and re-opening, but in the meantime you can use this as a work around to get the curve to display again.

For the developers, I am able to reproduce this on Linux with a GTX 1050ti with 2.83 ce76e17584 (2020-05-08 14:49) and 2.90 6f985574b7 (2020-05-08).

I know, It can be adjusted to work within same file -- but for links in other file it's not viable solution at all.

Thanks for confirming! :)

Add any material, add wave node and plug it to color in Principled BSDF

assuming that this screenshot is correct, material disappears at that moment for me & you don't need to save, close, reopen etc.

should've checked dates.

Note this works correctly if you explicitly plug in one of the Texture Coordinate nodes outputs ("Generated" for example)
untitled_corrected.blend

@fclem: is there a way to add the CD_ORCO GPU attribute by default for curves if no other coordinate is specified?
(feels like a bug to me...)
