Sketchy Edges show up through imported images?

Send help! If I apply Sketchy Edges to a model, all edges show up straight through any images in the file.

This is not a graphical issue– if I switch to another style (like Default), this stops. Why does this happen?

  • This problem occurs across multiple models- it’s not an issue specific to any one file.
  • Changing Level of Detail doesn’t do anything. Switching transparency quality from Fast to Nicer doesn’t do anything either.
  • This occurs with every Sketchy edge style, regardless of Faces style.
  • If I turn off Material Transparency, then the lines stop showing through the PNG, but that turns off all transparency in the PNG image. The bush looks like it’s floating in a white block. That doesn’t look good either.

There has to be a way to stop this! I would be grateful for any help. Thanks so much for your time.

This is a graphics issue. Try switching to the Classic Graphics Engine in Preferences>Graphics.

Share the .skp file so we can try it with different hardware.

Please put the full model number of the graphics card in your forum profile.

What Dave said, but SketchyEdge styles have been breaking things randomly on recent updates.

Thank you for the input. Hmm, I’ve tried switching to Classic Graphics Engine, but that doesn’t seem to have done it. I’ve added my graphics card to my forum profile.
Here is a simple sample file that showcases the problem I am having, with the same tree .png I used in the OG post.

Curiously enough, my friend who has used older versions of Sketchup (2017, and then 2021 I think?) told me they encountered the exact same problem, and never found a solution. Maybe this issue has existed for a long time. Hopefully there’s a workaround…

I am indeed seeing it with your image on my machine, too. Just for grins I exploded the image and used Pic2Shape from Fredo6 (Sketchucation) to trim the face to the image. Then there’s no bleed through. And there’s an appropriate shadow for the bush. Its edges could be hidden if desired.

FWIW, I use sketchy edges frequently in my models and haven’t had this issue. Not sure exactly what is causing it in this case.

Ah, so I may have to buy a plugin to get around this… Thank you so much for the help, Dave! When you use sketchy edges with images in your models, do those image files have any transparent areas? Or are they completely opaque?

At least for me, any image with a transparent area is affected by this problem. All the PNGs I’ve imported into these files are ones I drew myself (in Photoshop), so I thought that could have something to do with it. My half-baked theory was that the semi-transparent pixels in these images were causing Sketchup to treat the whole image as transparent- after all, there is some anti-aliasing on these drawings. I drew a rectangle in Photoshop (no anti-aliasing, no semi-transparent pixels), exported it as a .PNG, imported it into the sample file…. voila, the sketchy edges don’t show through!

So then I drew a more complicated shape with no anti-aliasing, no semitransparent pixels. In theory, Sketchup should treat this image the same as the rectangle. But… no avail.


Hmm, okay. And if I import the rectangle again, but this time with a transparent border, that also causes Sketchup to treat the whole rectangle as transparent. So I’m thinking, maybe, that the presence of any transparency in an image at all will trigger this issue.

I’m seeing the same thing in your models. It doesn’t appear that the images have transparency other than in the surrounding pixels.

Well, you could also try Image Trimmer which is part of TIG’s SKM Tools, also from Sketchucation. The benefit of using these extensions is that you can have shadows that show the shape of the bush/tree.

Another option would be to make multiple image exports from SketchUp and combine then in an image editor. Not difficult but it is limiting.

Maybe the developers will come up with a change that will fix it but until they do you ahve to figure out what mkes sense to get around it.
