Lines dont show

Post by linna » Mon May 13, 2019 8:49 am

Hi! I try to render my first sketchup drawing. Its this kind of triangle that is made from many different blocks. And its important to see the lines so that its shown that its not one piece. But when im rendering it to put it in website, it makes the lines dissappear. Do you know what is a problem over here.

There is no problem (likely). Twilight Render is a "photorealistic" renderer, which means it attempts to render things as close to a real physical object as possible. Since SketchUp's lines aren't "real", they aren't rendered.

There are ways to produce a non-photorealistic render that includes SketchUp's linework. The easiest way is to use Twilight Render's overlay feature which overlays the SketchUp image with the final render. You can learn about it here: https://www.twilightrender.com/index.ph ... te-overlay. It does require Twilight Render Pro, however.

The other method is to use "edge lines". In SketchUp, open the Twilight Render Material Editor and choose the material where you want your lines to appear. Click the "Advanced" drop down and check the box marked "Enable Edge Lines". By default, all the lines are enabled. But you can choose to only render lines on certain "creases" by changing what's called the "Hard Edge Angle". At 0, all lines are rendered. As you increase that to 90 degrees, it requires a sharper and sharper crease for the line to be drawn. You can play with that to reach the desired look.

Otherwise, it is possible to create an overlay effect in an external image editor (Photoshop, GIMP) by combining the render and an export of the SketchUp image.
