10 modeling tips to speed up rendering

If you (sometimes) have the time to wait 10 minutes or several hours to finally see the image you've worked on with love, it's not manageable for an animation! In this case, each second counts because it is multiplied by the number of images displayed per second.

A fluid animation requires about 24 frames per second of animation. Do the math!

Here are 10 modeling tips to speed up rendering:

  1. Limit modeling to what will be seen. This of course requires an accurate analysis of real needs. And do not forget the elements that are not visible but that have shadow or appear in the reflections;
  2. Split the 3D model into zones to display only the visible parts for the calculation;
  3. Do not detail the parts that will always be in the background, that will be in the shadow or that will be visible only a fraction of a second during a panoramic movement of the camera for example;
  4. Use models with few faces, but the mesh is smooth rather than the opposite. Warning! The edges viewed from the model, the contours, are not smoothed by the Mod Smooth;
  5. Use layers to easily hide details if they are too far to impact the image;
  6. Limit the level of detail of the model according to the final goal of the image. If you plan to compute the image in low resolution, you do not need to go into too much detail;
  7. Detail with a texture rather than modeling when possible;
  8. Use the Level of detail and Optimize Modifiers to reduce the number of faces in a mesh;
  9. To display an object, 3D Studio applies all the modifiers of the Pipeline one after the other to display the final result. Overwriting the Pipeline of an object with Collapse All therefore limits the work of 3D Studio Max to display and calculation;
  10. Run the gc() command in Maxscript to purge the file.
