does the Quad remesher plugin work well for you?
I can’t get a good result with it on very dense meshes like the one in the image:
I think I’m not setting it up correctly.
how would you use it in the case below?
has the .fbx at the end of the post.
I tried to save it as a blender file but it got more than 5Mb and the forum doesn’t accept it.
Quad Remesher generally works very well. Although it tries it’s best but it’s not a miracle worker. There are issues with your mesh like overlapping vertices and non-concentric rings which you may want to fix first but depends on how detailed and close you’ll be getting to this. I used Quad Remesher v1.2.1 on your mesh and obtained good results although not perfect. Retopo is on the left, your original is on the right. Still some artifacts towards the center.
I think you can maybe get better results with a little more experimenting or cleanup. I’m not the best modeler though so someone else may have additional advice.
Perhaps someone out there can provide advice on how to best construct these type of objects.
For you’re retopo did you use the settings I provided earlier? The output is very different. Attached is my retopo of your original file which will hopefully help although it’s not perfect but it’s close. I did use a “Smooth” sculpt brush to get rid of the artifacts right in the center. I had to zip the blend file to fit within the 5MB limit.
As I mentioned I’m not be best at modeling perhaps someone else can help with that. I would avoid very tight and sharp triangles otherwise the chance of artifacts is much higher. Another thing to avoid is poles like the one highlighted below. I also believe the subsurface modifier doesn’t like triangles.
The red is present because I’ve turned on “Face Orientation” on (option can be found within the “Viewport Overlays” header menu). This highlights faces that are facing the wrong direction. Blue is good, red is the back of the face.
As for the use of bevels you have 3 of them stacked and I’m not sure why. Usually one suffices.
This video might give you quick pointers on how to use bevels and which technique to use.
