Today I want to talk about a blender modifier that I find very interesting.
The Decimate modifier allows you to reduce the vertex/face count of a model mesh. Reducing the mesh can give you a very crude shape with minimal changes. but if you go too far with it will ultimately not resemble anything that you have modeled. so you are probably wondering why do I need this modifier or what can I use it for. I’ll tell you after I show you how to use it.
The Decimate modifier is not usually used on meshes that have been modeled carefully like a cosplay prop where all of the pieces modeled are exact. But if the mesh is the result of complex modeling or applied Subdivision Surface / Multiresolution modifiers, Decimate can be used to reduce the polygon count for performance increase.
Now you might be wondering what the Decimate modifier could be used for. Two possible uses are the creation of rocks and boulders for scenes and low poly mini-figures like Pokemon.
I have used the decimate modifier on a few occasions, I used it for my entry for the LUX3D mascot competition. I modeled the original face and then applied the decimate modifier to give a low poly design. so it can be used for that type of design work.
You can find a more detailed account of the Decimate modifier at the Blender 2.93 Manual, Click Below. It’s difficult to follow and gets very separated and detailed step-by-step instructions on how to use all of the features of decimate in Blender.
