Finishing up a model? Got 300 million polys? Is Blender's Decimate Modifier for you?
When do you need it?
Decimate
1. When you need to preserve detail in a low-poly 3D model
2. When you need to simplify complex 3D shapes for animation or gaming
3. When you need to reduce the vertex count of a high-resolution model
4. When you need to reduce the time taken to render a scene
5. When you need to optimize the mesh for better performance
Remesh
1. When you need to create more organic-looking models
2. When you need to increase the mesh density to preserve details in a model
3. When you need to create a low-poly version of a high-poly model
4. When you need to have control over the geometry of a 3D object
5. When you need to create complex topologies for 3D objects
In Blender, Decimate and Remesh are both modifiers used in the 3D software to reduce the complexity of 3D objects. The main difference between them is that Decimate reduces the complexity of the 3D object by reducing the number of polygons, while Remesh recreates the geometry of the object by restructuring the object’s mesh.
Decimate is often used to reduce the number of polygons in a high-resolution model to make it easier and faster to render. Remesh, on the other hand, is used to create more organic-looking models, as it recreates the geometry of the object. It can also be used to make a low-poly version of a high-poly model or to preserve details in a model by increasing the mesh density.
Decimate Modifier is an important tool in Blender, which helps to reduce the geometry of a 3D object by reducing the vertex count. The decimate modifier is used to simplify the forms and reduce the shading data in a 3D object, thus making it easier to render. It can be used to down-sample high-resolution models or to reduce the polygon count in a low-resolution model. By using decimation, you can simplify different types of 3D models such as meshes, morphs, and curves.
Put it to Use
The first step when using the decimate modifier is to select the 3D object that you want to reduce. Once selected, go to the Modifiers tab in the Properties panel and then choose the Subdivision Surface modifier. If you decide to keep the subdivision level high, then you will have an optimized mesh with improved resolution. The next step is to select the Decimate Modifier from the same tab in the Properties panel. This will bring up a list of options that you can choose from.
The first and most important option is to choose the type of Decimate Modifier. The types of Decimate Modifiers are Quadric, Classic, and Target. The Quadric modifier works by reducing the vertex count without changing the shape of the object, while the Classic modifier is used to reduce the complexity of the object by preserving its shape. The Target modifier is used to reduce the shapes of the object. There are other options available in the Decimate Modifier such as optimizing for pivot points, target faces, smoothness, triangulate, and corner weight.
Once you have chosen the type of decimate, the next step is to select the Exact Geometry Reduction Algorithm. This algorithm is used to determine the exact number of triangles that will be reduced. You can select any of these algorithms based on your preference. Each algorithm has its own advantages and disadvantages, so it is important to know them. Once you have chosen the algorithm, you will need to set the threshold level. This will determine the accuracy of the reduction.
The next step in using the decimate modifier is to choose the Deformable Resolution Option. This option is used to determine the resolution of the object before it is decimated. You can use this option to optimize the mesh for rendering or more organic and realistic-looking scenes. Once you have chosen the resolution, you can set the blend mode- which will determine how the geometry of the object is blended together.
The last step when using the decimate modifier is to define the Edge Length option. This will define the maximum length of edges that will be affected when decimation is applied. The shaded mode will also define the number of shades that will be applied during decimation. Once the options have been set, you can then hit the Apply button to apply the decimate modifier.
This is a live view so you can tweak it to just right where your polys are reduced while leaving your details intact.
Using the decimate modifier can drastically reduce the number of polygons in a 3D object and can significantly reduce the render time. This is especially helpful for high-resolution models that can take longer to render. It can also be used to simplify complex shapes, which can be useful when creating animations or when creating models for games. The decimate modifier is also very useful for optimizing and reducing the draw time of the 3D object, which can significantly improve the overall performance of the rendered scene.
