Everybody wants to speed up their 3ds Max rendering, who doesn’t want to? If you are renting a 3ds Max render farm, this would mean saving more time and of course, render cost. If you have your own rendering machine, this would mean lesser render time and RAM usage.

Not knowing how to optimize or improve rendering on 3ds max will usually result to high RAM usage and may crash your scene or you may experience very slow project rendering. This is simply because the project will need to continuously read and write data to the hard drive, and hard drives are a thousand times slower than RAM.

So, how do you speed up 3ds max rendering?

As Autodesk explained it, there are ways on how to do it.Autodesk explained it, there are ways on how to do it.

  • Avoid using more memory when rendering by simply disabling “Conserve Memory”. (Rendering > Render Setup > Processing tab > Conserve Memory > Remove the selection)
  • Try to optimize your scene where possible. Using tools such as the Optimize and ProOptimizer Modifiers on as many dense objects as possible can increase renders speeds and scene calculations.
  • Reduce the number of lights you use in your scenes when possible. Using fewer lights would mean less calculation which will result to faster render times. Consider using Light Lister to disable lights.
  • Disable Receive / Cast Shadows on objects that do not require them.
    (Right-click the object > Object Properties > Rendering Control > Receive Shadows/Cast Shadows)
  • Disable/Exclude objects from Caustic and GI Calculations.
    (Right-click object > Object Properties > Mental Ray and remove selections where necessary.)

  • Disable/Reduce the number of reflections/refractions in your scenes when possible. Using fewer reflections/refractions would mean less calculation which will result to faster render times.
  • Know the difference between copy and instance, simple but effective.
  • Reduce Geometry(polycount) in your scene, the more geometry, the bigger the scene file which means longer rendering/more RAM needed. GarageFarm.co, a 3ds max render farm, explained this in detail over their website.
  • Remove unwanted object on your scene. Optimize global illumination caches by controlling its memory usage.
    • Irradiance map – use lower Min/Max rate, and more loose threshold values (higher Color threshold, higher Normal threshold, lower Distance threshold) when possible.
    • Photon map – Memory usage depends on the number of photons stored. Try reducing the diffuse subdivs for the lights, or by increasing the Max Density when possible.

There are a lot of ways you can optimize or speed up your rendering on 3ds Max. You just need to know when and where to do some tweaking. As mentioned above, this would result to faster rendering and lower cost. Good luck and happy 3ds Max rendering.
