✱ Q&A: Using Maxwell Grass 'Level of Detail' for Faster Renderings

Here's something thing that comes up every once in a while regarding using the Maxwell Grass extension - running out of memory. Those grass blades can take up a lot of RAM when rendering and if your surfaces that you apply the grass to are too large, the rendering can be extremely slow and sometimes even fail. 

And no one likes a failed rendering!

So here's a quick screen shot of some settings to look into when using the grass extension called Level of Detail (LOD):
 


Use the L.O.D. settings in the Maxwell Grass extension to control falloff of grass blades.

Basically if you set it up correctly, the further away your scene gets from the camera POV, less grass blades are generated. You can control how this works. This is a HUGE deal when your surfaces are expansive. The image above is an extreme example because of how closely I placed the distance values together, but it illustrates how they work. Once the distance passes the Minimum value, the blades falloff to the Maximum Density and then hold beyond the Maximum distance value. This way there is no step in the amount of blades, rather you get a nice even gradient from full to partial density.

There's a bit more info about this in the Maxwell Render help documents near the bottom of the page which you can reference here.

Use this tip to speed your renderings up drastically!

This tip also comes in really handy when using my Maxwell Grass Preset Pro Pack. Check it out and take your images to the next level if you're using SketchUp, FormZ or Bonzai3d.
