So I have been following this tutorial https://www.youtube.com/watch?v=RzlRzJpG7vc&t=13s and I am stuck because my material gets stretched on the edges, see pic attached. I think it is because of the solidify modifier because as I play around with the settings, the stretching goes away, but appears in other places. So I figured it had something to do with solidify, but I don't know what to actually do to fix this. I have already uv unwrapped of course. Thanks in advance! :-)
Not because of solidify, but solidify + subsurf.
Rim between two faces shares the same place in UV coordinates, so that's why it looks stretched, but solidify makes this rim more visible from front.
I think, the easiest way to solve this is applying solidify and making UV again.
But adding loopcuts also makes it less visible:
