Voxel Remesh Download [BEST]
Kam Bergmann
The resolution or the amount of detail the remeshed mesh will have.The value is used to define the size, in object space, of the Voxel.These voxels are assembled around the mesh and are used to determine the new geometry.For example a value of 0.5m will create topological patches that are about 0.5m(assuming Preserve Volume is enabled).Lower values preserve finer details but will result in a mesh with a much more dense topology.
The voxel size also be adjusted from the 3D Viewport using R.Using the shortcut displays an interactive grid overlay showing the resulting voxel size.Moving the mouse closer to center of the grid decreases the voxel sizewhile moving away from the center increase the voxel size.Holding Shift` increases the precision; adjusting the voxel size in small increments.Holding Ctrl adjusts the voxel size relative to the current voxel size.
I have been watching a youtube channel that helps with beginners and explains the use of multi resolution, and when to use the voxel remesh here is the link. its very helpful

I thought i saw in a video where somebody pressed something and it overlayed an adjustable grid so you could see what size your voxels would be before you hit remesh but cant find the actual option to do it.
Hello @Thesonofhendrix, I had the same questions the other day and someone share the shortcut with me.
In sculpting mode, press Shift+R to display the Voxel grid, use your mouse to select the right resolution and press LMB, then press Ctrl+R to apply your Voxel remesh.
Remesh in sculpting crashes every time i use the remesher in Shift+R/Ctrl+R and i miss a click to apply the voxel size. so it think i meant 0.0001 and its so sad to see my progress go :((((( is there a way around that?
OK. I actually thought the minimum voxel size had been adjusted recently, to avoid too much detail. Are you using the latest version? Maybe it has been fixed since the 2.93 alpha builds started, so you could try the latest alpha build.
Since the introduction of the new Voxel remesh option in the Remesh modifier, this has been the default mode. But as it works on the global measures, adding the modifier to a large object can be quite demanding.
The Voxel Remesher is meant to be used in this same way. Typically, we start with the voxel size set very large so that we are working with just a few polygons while we block out a shape. Then, when we don't have enough polygons to represent the forms we are trying to create, we reduce the voxel size and run the remesher again.
Perfect! Increasing the voxel size also increases the size of the polygons that will be generated when we run the Voxel Remesher. This also means we will have fewer polygons, which, in this case, is a good thing. Having fewer polygons will make the sculpture easier to work with while we block out the largest of our major forms.
When working with the Voxel Remesher, we have to make our changes in small increments; we make a change with our brushes, then we run the remesher again. Now that we have a protrusion coming out of the sphere, we need to remesh the polygons so that they support the new form.
You might be wondering whether it's excessive to use the Voxel Remesher in this way. Not at all! This is how it's meant to be used. We can run the remesher as many times as we need to. Any time we begin to work on a new form and the polygons become stretched out, it's time to run the remesher again. You might run the Voxel Remesher 10, 50, 100, or even 1,000 times during a sculpting session; that's why we have the keyboard shortcuts.
Perfect! Now we can add more details at this new voxel size. We should avoid decreasing the voxel size too much too quickly. If we go too quickly, we will end up with jagged artifacts on the surface of our mesh. If you recall back to our example in the Practicing the basics of the Voxel Remesher section, this is what happened to the character's neck. If we end up with some of these jagged edges, we will have to find a way to smooth them out later. So, it's easier if we simply don't introduce these issues in the first place.
Working from low detail to high detail is the best way to achieve good results in our sculptures. Another way to think about voxel size is in terms of resolution. Resolution describes the amount of detail we can achieve based on the current size and density of the polygons.
Resolution in an image and resolution in a 3D sculpture work very similarly. However, we have an advantage in 3D sculptures: we can increase the resolution by decreasing the voxel size, then running the Voxel Remesher.
The unapplied remesh appeared fine in solid view, and with a bit of processing load in edit or wireframe, but that was to be expected. There wasn't as much difference between the original head and the remeshed one, but I disregarded that as my computer could barely handle any lower of a voxel level, and assumed that the cause of the definition, or lack thereof.
I have tried unwrapping the UV again and raising the voxel count to no avail, and am unsure on how to proceed. When peering inside the mesh, the modifier appears to be working fine, but not so much on the outside.
I have no clue what is causing this. I would preferably like to test with lower voxel sizes to see if that is the issue, but I'm pretty sure that would melt my laptop's CPU (it apparently hit 114% by reducing the voxel size from 0.03 to 0.02) Help will be greatly appreciated, .blend file below.
Occasionally we need to deal with objects that has a completely unworkable mesh in Blender. It can be anything from a sculpt made with dynamic topology to a photo scanned object. In those cases, remeshing can be a quick way to help ease up or even solve the problem. Especially if the manual way of retopology isn't a viable option.
To use remeshing in Blender, select your object, go to the properties panel and find the object data tab (green icon). Expand the remesh section and find the voxel and quad remeshing options. Click the remesh button to remesh using the selected method. An alternative is to use the remesh modifier.
Blender has several tools to achieve this. There are two different types of remeshing available through the object data tab in the properties panel. Voxel and Quadriflow. These are the newest additions to Blenders remeshing toolset.
Note here that even if there is a voxel remesh option available in both the object data properties and the modifier, the result from each is different and the destructive option found in the object data tab is often more accurate and generate a better result.
It is available as a shorthand in the header of the 3D viewport while in sculpt mode. You can also press Ctrl+R to run a remesh operation from within sculpt mode. This is likely how you will interact with it most times if it is used as a sculpting tool.
The voxel remesher is often used while sculpting as an alternative to dynamic topology. It is accessed while in sculpt mode. With this tool, you can manually set the level of detail you want by adjusting the voxel size. If you want a higher level of detail, you reduce the voxel size.
We have covered remeshing in Blender and how you can incorporate it in fixing bad topology in your meshes. Blender has various remeshing options and each has a specific use case. When sculpting, you should use the voxel remesher in Sculpt mode. To fix bad topology, the remesh tools in object data properties are suitable. The remesh modifier should be used to create block-stylized art and create quad-based topology. The voxel remesher in the modifier and the one in the object data properties are interchangeable.
By pressing SHIFT+R you can visualise a grid showing the voxel size that can be resized by moving the mouse before remeshing with CTRL+R. It's useful if you don't know what value to type in the voxel size menu.
By holes, we don't mean the genus hole (hole of a donus), but instead mesh that are not watertight/closed. Typically, what it means is that before applying the remeshing, every holes will be filled, similarly to the Trim tool or Hole filling feature.
Create lower multiresolution levels for the voxel remesh. If you use the checkerboard pattern to set a resolution, and set build multiresolution to 1, the remesh operation will first create a voxel mesh at double the checkboard size, project it onto your model, then subdivide, and project again. This can be a good way to both generate a clean mesh with even polygons, and have a lower resolution control mesh.
In this video I had initially planned to do a quick demo on how the Voxel mode of the remesh modifier, that has been added in the 2.83 version, could be used to block-in a model to be further sculpted. Eventually I went "In the Zone" and it turned into a long anatomy practice. I kept experimenting with this technique for about 3 or more hours.
(6.) When trying to import the file I made in Shapr3D before doing remesh following the same steps I get this error message in Forger Classic: Error loading file, Error loading the mesh, check that the mesh is valid, the size isnt too tiny or huge or if it has multi overlapping UDIMs.
Instant Meshes Remesh, as you might guess is an addon to remesh your mesh. For example when you sculpt with Dynotopo, the topology is so ugly that you need to remesh it. This can be done by hand but it takes usually a lot of time. Sometimes you can get away with automatic remesh. Blender has a build in Mesh modifier, but Instant Meshes Remesh that uses the Instant Remesh software is more sophisticated.
I am trying to process them in Blender but it isn't going too well. I am basically remodeling each model and that is too time consuming. I can do a voxel remesh in Blender by applying a solidify modifier to each piece to give it some watertightness, but that is not as clean as I'd like (and it adds some thickness to parts of the model I would rather leave as is). Then remeshing it from that point is also problematic.
Can 3DCoat handle a mesh like this and voxel-ize it before remeshing it? Is that even a thing people use 3DCoat to do?
Thanks.
