Exact Decimate: Triangle Count Precision

by Corey Kinard in Addons

What is Exact Decimate?

Are you tired of the guesswork involved in decimating to a specific triangle count for your 3D models? The traditional decimation method rely on ratios, making it challenging to achieve your desired triangle count, especially for high-resolution meshes, like those used for 3D printing.

With Exact Decimate, you can effortlessly decimate your models with precision and ease. Simply select your object, specify your desired triangle count, and hit 'Decimate.' It's that simple. Your mesh will be optimized to match the specified triangle count or even lower (depending on the initial triangle count). Need to make adjustments? No problem. Enter a new triangle count, hit 'Decimate' again, and watch your model update. Once you're satisfied with the results, just apply the created Decimate modifier.

Whether you're a real-time 3D artist, designer, or 3D printing enthusiast, Exact Decimate is your go-to tool for simplifying and perfecting the decimation process. Say goodbye to the frustration of hitting your triangle count target – Exact Decimate has got you covered.

Once activated, you will find Exact Decimate under the "Tool" tab.


  • Exact Decimate relies on the Blender Decimate modifier, which means it inherits any limitations associated with this modifier. 
  • Decimating high-resolution assets can be time-consuming and may vary depending on your system specifications. As an example, the process for a high-resolution model, like the hair model mentioned above, could take around 10 minutes. It's important to note that Blender reruns the process when you apply the modifier. For efficient workflow, consider decimating down to a more manageable triangle count (e.g., 1,000,000 or less), apply the modifier, and then use that as a starting point if further reduction is necessary. Your machine and spare time will thank you.
