By increasing it you can reduce the number of polygons in the mesh but the mesh may look less rounded and not as attractive. This parameter is only available if 'Mode' is set to 'Mesh'. It is the value in the VDB voxels which is considered to be on the surface of the mesh. This setting is only used when 'Mode' is set to 'Mesh'. For example, increasing the exterior band width excessively will try to fill too many voxels with fog data than Cinema 4D can handle and it may appear to freeze. It is recommended that you do not change these settings from the defaults unless you know exactly what you are doing. The interior and exterior band widths control how many voxels to fill inside and outside the volume respectively. This is mainly intended for use when meshing volumes. Fill Interior VoxelsĬhecking this switch will fill all the voxels inside the surface of the generated object. They are only visible when 'Mode' is set to 'Mesh'. These are options used to control the nature of the generated mesh. For the most part you can leave the default values as they are, but if you need to exclude very small or very large particles, you can alter these limits. If the sphere size is outside these limits, it will not be included in the mesh.

These are the limits on the size of the virtual sphere generated around each particle by the mesher (see the discussion below for full details). This controls the size of the spheres generated around each point or particle.
They have no effect on any objects if the object's 'Mesh Mode' is set to 'Surface'. These settings are only effective if the 'Mesh Mode' for a polygon object is set to 'Points' or if the source object is a spline, a null object, or an X-Particles emitter. Internally, the 'Voxel Size' parameter is multiplied by the 'Half Width' value and the result acts as a background or default value for the active voxels. Reducing it can reduce the number of polygons generated and make the mesh appear a little sharper, but if you make it too small, you may start to see artefacts and holes appearing in the mesh. It controls the width of the 'narrow band' of voxels included in the surface (see the discussion below). Much of the time, you can leave this alone. See the discussion below concerning voxel size and scale factor when selecting values for these options. This parameter is not available if 'Link Voxel Size' is checked. This can be made lower than the voxel size in the editor for higher resolution and better results. The voxel size when the mesh is rendered. As the voxel size is lowered the resolution of the mesh increases and any animation in the viewport will be slower. Generally speaking, this should be kept as large as possible for maximum speed in the viewport. The voxel size when the mesher is shown in the viewport during scene editing. If this switch is checked, the 'Voxel Size (Render)' parameter is not available, and will use the value from 'Voxel Size (Editor)'. If this switch is checked, no mesh will be visible in the viewport and will only be seen when the scene is rendered to the viewport or picture viewer. This mode was named 'Fog' in previous versions of X-Particles but the functionality has not changed. Additional controls become available when this option is selected. You can render this with an Explosia FX object. When you select this mode, another set or parameters becomes available, as described below. As with the 'Mesh' option, the result depends on the source object options. The parameters in this section allow you to control the sphere generation. In this mode, instead of creating a surface, the mesher will derive a voxel grid - which will not be displayed - from the object and then fills that with spheres. The resulting mesh depends on the options chosen for the source object - see the ' Mesh Mode' parameter for more details. This generates a polygonal mesh from the object(s) in the 'Sources' list.
The mesher can operate in three different modes. These are general options applying to the mesher. Which ones you will see depends on the setting in the 'Mode' parameter: Parameters General quicktabīelow the General section there are several other sets of options. The object's interface includes these sections:įor the buttons at the bottom of the interface, please see the ' Common interface elements' page.

This is an implementation of the OpenVDB Mesher for X-Particles.
