In Layout, Hybrid mode, the edges are occulted by the image. Worse, the image is rasterized under the transparent portions of the image (the face boundaries in the cube are jaggy).
Is the raster version using the Low quality setting? This was changed in 2023.1 to something like 36 DPI or even lower, and the Medium setting corresponds approximately to Low in 2022. Only the High setting is unchanged.
The problem is not in the quality of the image but in the fact that the underlying edges of the geometry (i.e. the cube) visible by transparency are not vectorized, and even hidden.
The screenshots were taken from Layout, not from a generated PDF.
This was in case this was related to the reengineering of the rendering pipeline, which may be different between Mac and Windows.
Unfortunately, I cannot open Layout 2022, nor any previous version of Layout. I donât know why. Maybe this has been like this since long, that is, you can only use the latest installed version of Layout.
I would guess that you get the same occlusion when Vector rendering a Hidden Line view. Hybrid rendering just superimposes a Raster view with no edges with a Hidden Lines vector view. Vector views do not support any kind of transparency.
Hi Fredo, this happens with any transparent face. If you have glass represented by a simple color with less opacity the effect is exactly the same in Hybrid.
I suppose a PNG image or material painted in a face is still treated as a face with a transparent material.
Maybe Sketchup should read fully transparent pixels of an image as not being there, but that calculation might be hard to solve in Layout.
Raster mode works differently than Hybrid mode, as in Raster what you see is what you get, and edges get blended in the background raster and take into account alpha of images and materials, while in Hybrid we want our edges to be replaced by vectors and independent from the background. So, in hybrid all edges are removed from the raster part of the viewport and they are replaced by vectors. As the vectors are calculated without face transparency to be taken in account, every edge behind a transparent face is removed.
So, I donât think this is a bug, while I think it could become a cool feature request as long as vectors would be shown only through fully transparent pixels or faces.
My honest opinion is that I wouldnât like this calculation to occur in my projects, if it would imply even more time reloading hybrid viewports. I work a lot with those.
I came across a bug very similar to this in another version of SketchUp - when I switched the transparency rendering to the more expensive ânicerâ option in the style, the issue ceased.
Obviously layout is dealing with different things also, but it might be worth a try.
In Sketchup, the transparency is correctly handled, whether with Faster or Nicer
In Layout, this makes no difference. I think this is specific to the Vector mode. When the model is rendered in Layout, the zone occupied by the image is rasterized, regardless of transparency.
