I have softened the edges but when I put it through Vray 6, you can still see all the lines and the reflection is all over the place. I just wanted it to be clear and realistic.
What version of SketchUp are you using? There is no 2023 Free Plan as your profile shows. What operating system? “2023” as you put in your profile is not an operating system. Memory is not the graphics card, either.
Share your SketchUp file and a screenshot of what you are seeing in Vray.
I am using a free trial at the moment for SU 2023. I’ll attach pictures
As I asked, share your SketchUp model file.
Also correct your forum profile.
That is NOT the Free Plan.
I am a new user so it wont let me as the file is too big. I’ll explain what I have done though pictures.
First I created two arcs and joined them together as a 2D shape.
I then used the eraser tool to delete the lines. However, when I render the image, it does not come out clear and smooth, it comes out with the lines as shown in the previous image.
Try making the arc have more segments to make it smoother looking… SketchUp draws in faces / facets so you might have to add more detail to make it look right in the render.
I could not replicate your problem in normal rendering mode, but it does occur when using the “interactive” render. It seems it doesn’t properly track changes in face normals (like smoothing/unsmoothing), and you need to ‘force’ an update—grouping and exploding (or simply undo-ing after grouping) the relevant faces seem to work.
I think you’ve hidden the edges to SketchUp using the “hide” modifier on the eraser (or maybe via entity info) - this just stops the edges being drawn in SketchUp, but v-ray still sees the angle of each glass piece - as this is what is there.
You want to use the Soften/Smooth bar - this creates a rendering trick which tells a renderer to see the light striking the edge as if it was hitting at a different angle.
left to right:
Edges HIdden (you can see the faceting as you can in yours)
Edges with Soften and smooth toggle (this is the same as 180degrees I think) so causes errors
or what you want to use -
Edge Softening adjusted to around 20degrees using the soften edges - soften/smooth bar.
You can select the geometry OR you can select the group/component and do it.
Sometimes you need to move the slider a little for it to kick in - even if it looks like it’s been set.
I generally use that soften smooth bar at somewhere between 20-30degrees across an entire model.
You can use ThomThom’s CleanUp3 to set it across an entire model too - as it will often solve the same faceting issues on imported geometry.
Thank you so much for all of your help I really appreciate it! I’ve managed to make it work by increasing the segments in the circle making it higher poly.
Thank you again!
This is a really good feature to use and one I will definitely try in the future! Thanks so much
You may need to do a combination of both - increasing the geometry is a brute force way of doing it and will count towards increasing your render time and memory useage- you want to keep the number of segments as low as you can - I think I had 24 in the semi-circle in my example here - which is the same as your original model.
You can’t see any evidence of it on the glass itself in my little render
