Send your geometry from mudbox over to maya as a guide for adding new geometry around it.Ī rig set up in Maya can be imported along with the model. Reroute the topology to match the detail. Sometimes as we sculpt, the flow of topology on the original mesh may not match up with our sculpted result. You can however transfer paint layers from bad UVs onto good UVs for example. Paint layers are based on the UV layout but sculpt layers are not. You can tile the UVs in Maya/Mudbox also so as to dedicate more resolution to each area. obj file and select the object in Mudbox and import UVs. You can create UVs in Mudbox from the menu which will break each face up into shapeless coordinates. Meshes with topology problems such as non-manifold topology will not be able to subdivide in Mudbox. In the attribute editor > set subdivisions to 03 (for example)Ġ5 Using the’ send to’ features in maya and mudbox. Under subdivision hit ‘create’ a new approximation. Go into rendering editors>mental ray> approximation editors. In order for the displacement to work the geometry needs to subdivide at render time. Plug the file into the displacement of the material. For exporting displacements – export as a 32bit exr. A normal map is only the illusion of detail where as a displacement creates geometry. Choose ‘tangent based’ for geometry that is going to be deformed. Change the method to subdivision instead of raycasting (as we are working with the same mesh that detail has been added to). The target model is the level 0 low resolution in mudbox and the source model is the highest level sculpt. A normal map is like a bump map that allows you to work with a low resolution model but makes it appear highly detailed. This will automatically set up a layered shader of the different paint layers.Ġ4 Transferring normal and displacement maps. Then select the object and export as an fbx. If you want to export your paint layers separately, make sure that ‘flatten layers on export’ is turned off in the preferences. You can export your paint layer by right clicking and exporting maps. When exporting from Mudbox, check window>preferences and check the settings e.g. In Maya, freeze the transformations before exporting. The grid size in Maya and Mudbox don’t match. obj file exports the geometry and UV map etc.fbx contains more detail. These can be useful if you’ve never worked with materials before.Exporting as an. Click an item in the tray to apply it to your active model in the 3D View. Mudbox provides the following CgFX-based material types:Ī number of pre-made materials are available from the Materials Presets tray. Texture maps allow you to add visual detail that would be otherwise difficult to achieve by sculpting alone and achieve a more realistic appearance. You can import images as paint layers to use them as texture maps and create the appearance of bumps, apply a logo image, apply a pattern or a marbled color image for example. A texture map is an image you add to an existing material to enhance its appearance beyond what the material's basic properties provide. Mudbox lets you paint directly on a model using the paint tools to create texture maps. You can edit this material, assign other pre-made materials from the Material Presets tray, or create your own custom CgFX materials as well as apply texture maps. A material can also be categorized by the mathematical algorithms that its based on, for example: Blinn, Lit Sphere, and so on.Įvery model in Mudbox is assigned the Mudbox Material by default. A material is a collection of properties assigned to a model that control how its surfaces react to light and appear in the 3D View.Įxamples of material properties include: color, glossiness, and transparency. To make your model appear in different colors, have matte or reflective characteristics, and so on, you must edit or apply its material characteristics.
