How to use a Bump Map in SOLIDWORKS Visualize

Improving the realism of your appearances is key when working in SOLIDWORKS Visualize. In this tutorial, you will find out how to use Bump Maps to add a customised “textured” look to your renders.

This tutorial focuses on how to use Bump Maps in SOLIDWORKS Visualize to add a customised “textured” look to your renders. It’s the first of five tutorials based on the content of this video where our Technical Manager, Ed Hawkins, recreated a classic Tiger Woods shot from The Masters Golf Tournament.

The techniques covered are as follows:

So without further ado…

Why use a Bump Map?

A Bump Map will make a model look more geometrically complex, without having to model in the complexity manually. Bump Maps are a superb way of quickly improving the realism of an appearance.

Before going through and creating a new appearance, a bump map will be sourced, either from within Visualize, or from an image library on your computer, or even the Web. Simply Google searching for the name of the appearance you’re looking for followed by “Texture”, “Bump Map” or “Normal Map” will often yield plenty of results. However, make sure that the image you’re using isn’t copywritten before including it in your render!

How to apply your chosen images to your render

Firstly, apply a material which is similar to the one you’re after. This can be done from Visualize’s existing appearance library.

After applying the appearance, the Bump Map can be added from the Texture tab when the appearance is selected. In the example shown above, a Golf ball bump map has been applied to the model using an image. After application, the mapping may need to be corrected on the surface. If this is something you are struggling with, make sure to check out our mapping and scaling textures in SOLIDWORKS Visualize tutorial.

There are a few Bump Map options which can be modified to get the appearance looking right:

  • Enable texture: Use this to turn the Bump Map on and off.
  • Invert bump: This inverts the Bump Map, making concave areas convex.
  • Treat as normal map: Different images can be used; Bump Maps (greyscale) or Normal Maps (RGB). Use this option to toggle between them.
  • Bump Displacement: This will be covered in a separate blog see Using Displacement Maps.
  • Bump strength: The most important option, it can be varied to adjust the Bump height. Negative values do the same as inverting the Bump Map.

So there you have it. You should have a must more realistic appearance after adjusting these settings. You can take it even further by combining this map with an Alpha Map to create holes in an appearance, or a Specular Map to add location specific highlights. Give it a try.
