I made the SVG that's attached to this post. When I import it into Blender, for some reason the black edge of the oval shape is not rendered. Now, I could fix that in Blender, but I think the easiest and best way is to fix it in Inkscape, so that when I export the same image, the animation and PNG at least look the same.

Can someone tell me what is missing in the SVG? Why it does add the black edge for the fonts, but not for the oval shape? It may be a silly detail, but I don't see it.

I also contacted the Blender forum for a possible solution: https://blenderartists.org/t/make-a-3d-model-of-a-svg-image-and-animate-it/1391614

I would use Stroke-to-path on the oval, and probably union the K to the oval.

I also believe that the problem is in the contour. Blender is quite demanding in importing svg files.

For example, in an experiment of this type, I noticed that the drawing must have solid colors, that is, without gradient tones... otherwise Blender imports the drawing in shades of gray. I leave here the link of the video in which I did the experiment, maybe it will be useful...

Woohhooohh! That did it. Thanks a lot!

Thanks, I did multiple stroke and objects to path, and also removed all gradients, since they're not needed in blender anyway when you are creating your own gradients (took me a moment to realise that!) worked like a charm after that, I also removed the stroke from text, that seemed to be causing an issue. You guys definitely pointed me in the right direction, I've not used blender in about a year so also getting to grips with the new changes in 4.0.
