Subdivision Reversion in 3ds Max: A Complete Guide to Using the Script



Subdivision Reversion 3ds Max Script Download PDF




If you are a 3D modeler, you probably know how important it is to have a good control over the level of detail of your meshes. Sometimes, you need to subdivide your mesh to add more detail and smoothness, but other times, you need to revert back to a lower subdivision level to edit, unwrap, rig, or export your mesh. This is where subdivision reversion comes in handy.

Subdivision reversion is a process of recreating the subdivision levels of an already subdivided mesh with 100% precision, while maintaining the UVs. It allows you to switch between different levels of detail without losing any information or quality. It also supports a wide variety of subdivision algorithms, such as Catmull-Clark, Doo-Sabin, Loop, Butterfly, and more.


In this article, we will show you how to download and use subdivision reversion 3ds max script, a powerful tool that can help you with subdivision reversion in Autodesk 3ds Max. We will also give you some tips and tricks for using this script effectively and efficiently.


What is subdivision reversion and why do you need it?




Subdivision reversion is a technique that allows you to reconstruct the original or lower subdivision levels of a mesh that has been subdivided using a certain algorithm. For example, if you have a mesh that has been subdivided using Catmull-Clark algorithm twice, you can use subdivision reversion to get back the original mesh or the first subdivision level.


Subdivision reversion is useful for several reasons:


  • If you are a 3D modeler, you can experiment with different subdivision algorithms and choose the one that best suits your needs.



  • If you buy or download a 3D model online that has its modifier stack collapsed or baked into geometry, you can use subdivision reversion to reconstruct the lower subdivision levels and then edit, unwrap, rig, or export it as you wish.



  • If you need to collapse your model at some point in your production pipeline for performance or compatibility reasons, you can use subdivision reversion to get back the higher subdivision levels later.



  • If you apply a turbosmooth modifier to a reconstructed subdivision level, you will get exactly the same mesh as the original one.

To use the script on a mesh, follow these steps:


  • Select the mesh that you want to revert.



  • Click on the "Revert" button on the toolbar. A dialog box will appear with some options.



  • Select the subdivision algorithm that was used to subdivide the mesh. If you are not sure, you can try different algorithms until you find the one that matches your mesh.



  • Select the subdivision level that you want to revert to. You can use the slider or type in a number. The higher the number, the lower the subdivision level.



  • Click on the "OK" button. The script will create a new mesh with the reverted subdivision level and select it for you.



Tips and tricks for using subdivision reversion 3ds max script




Subdivision reversion 3ds max script is a very powerful and useful tool, but it also has some limitations and caveats that you should be aware of. Here are some tips and tricks for using this script effectively and efficiently:


How to optimize your workflow with subdivision reversion




If you are working with multiple meshes that have been subdivided using the same algorithm, you can save some time by using the "Batch Revert" button on the toolbar. This will allow you to select multiple meshes and revert them all at once, using the same settings. You can also use the "Batch Revert Selected" button to revert only the selected meshes in your scene.


If you want to keep both the original mesh and the reverted mesh in your scene, you can use the "Copy" option in the dialog box. This will create a copy of the original mesh before reverting it, so you can have both versions available for comparison or further editing.


If you want to revert only a part of your mesh, you can use the "Selection Only" option in the dialog box. This will revert only the selected polygons or elements of your mesh, leaving the rest unchanged. This can be useful for fixing some local issues or creating some variations in your mesh.


How to troubleshoot common issues with subdivision reversion




Sometimes, subdivision reversion may not work as expected or produce some errors or artifacts in your mesh. Here are some common issues that you may encounter and how to fix them:



  • If subdivision reversion fails to create a new mesh or gives an error message, it may be because your mesh is too complex or has some invalid geometry. Try simplifying your mesh by removing any unnecessary polygons, vertices, edges, or modifiers. Also, check your mesh for any overlapping faces, flipped normals, open edges, or non-manifold geometry and fix them if possible.



  • If subdivision reversion creates a new mesh but it does not match your original mesh or has some distortions or gaps, it may be because you selected the wrong subdivision algorithm or level. Try changing these settings until you find the one that matches your original mesh. Also, make sure that your original mesh has not been modified after being subdivided, as this may affect the accuracy of subdivision reversion.



  • If subdivision reversion creates a new mesh but it does not preserve your UVs or other attributes of your original mesh, it may be because these attributes are not supported by subdivision reversion. Subdivision reversion only supports vertex colors, vertex alpha, vertex illumination, smoothing groups, material IDs, face maps, and UVs (only one channel). If your original mesh has any other attributes that are not supported by subdivision reversion, they will be lost when reverting.



How to customize the script settings and preferences




If you want to change some of the default settings or preferences of subdivision reversion 3ds max script, you can use the "Settings" button on the toolbar. This will open a dialog box where you can adjust some options, such as:


  • The default subdivision algorithm that will be selected when you run the script.



  • The default subdivision level that will be selected when you run the script.



  • The default action that will be performed when you run the script (revert, copy, or batch revert).



  • The default option for reverting only the selected polygons or elements of your mesh.



  • The default option for preserving the UVs of your mesh.



  • The default option for displaying a progress bar when reverting your mesh.



  • The default option for displaying a warning message when reverting a complex mesh.



You can also reset the settings to their default values by clicking on the "Reset" button.

FAQs




Q: What is the difference between subdivision reversion and turbosmooth?




A: Turbosmooth is a modifier that applies a subdivision algorithm to your mesh, increasing its level of detail and smoothness. Subdivision reversion is a process that reconstructs the lower subdivision levels of your mesh, decreasing its level of detail and smoothness. Turbosmooth and subdivision reversion are complementary techniques that can be used together to create high-quality meshes.


Q: Can I use subdivision reversion on any type of mesh?




A: Subdivision reversion works best on meshes that have been subdivided using one of the supported algorithms (Catmull-Clark, Doo-Sabin, Loop, Butterfly, etc.). It may not work well on meshes that have been subdivided using other algorithms or methods, such as displacement maps, sculpting tools, or boolean operations. It also may not work well on meshes that have been modified after being subdivided, such as by adding or deleting polygons, vertices, edges, or modifiers.


Q: How can I get the best results with subdivision reversion?




A: To get the best results with subdivision reversion, you should follow these tips:


  • Select the correct subdivision algorithm and level that match your original mesh.



  • Simplify your mesh by removing any unnecessary geometry or modifiers before reverting it.



  • Check your mesh for any errors or issues that may affect the accuracy of subdivision reversion, such as overlapping faces, flipped normals, open edges, or non-manifold geometry.



  • Use the "Copy" option if you want to keep both the original and the reverted mesh in your scene.



  • Use the "Selection Only" option if you want to revert only a part of your mesh.
