How to Apply Displacement Map in Maya
You will need to be able to set up the material in Maya to apply a displacement map. First, you need to be familiar with the basics of the material editor. Then you will need to create a displacement map. This map will move the white portion of the image away from the object. You will need to set the offset parameter to move the displacement according to the position of the texture map compared to the object.
In Maya, you can use the Hypershade plugin to export the displacement map in 32-bit TIFF format. This format can cause problems in Maya. To convert the 32-bit TIFF into a 16-bit EXR format, you can instead use Nuke or Photoshop. Make sure that you convert the displacement from grayscale to RGB color, as grayscale will cause problems. Once you have the correct format, you can assign the texture of your object and bake it into the geometry.
Next, you need to apply the displacement map. You can apply a bump map to mesh materials by placing it in the material’s Attribute Editor. The bump2D node has a bump mapping slot. The bump depth value is used to determine the volume of the bump effect that occurs during rendering. A normal value for the initial value is 1, but 0.5 is a good starting place.
You can apply a displacement map on a model by selecting one with a checkerboard texture. Select the checker node that you want to apply the displacement map to and then double-click it to make the map visible. Next, select the location where you want to apply the displacement mapping. When you are finished, select the final material and then close the material editor. There are two windows for this, one for the displacement and another for the texture.
Next, open the attribute editor. Select the Shape node. You can then choose the subdivision or displacement control settings. Generally, you want to set the edge length to 4.0, but you can decrease the edge length if you want a higher quality displacement. You can also disable displacement map filtering to retain high frequency details. You will need to ensure that the displacement map matches your texture and matches the size of your mesh if you are using it to create a rig.
To add more details to your geometry, you can create a bumpmap. A bump map can make fine details that have been displaced indistinguishable from the rest of your geometry and can help you save a lot on render time. You’ll also find that bump maps can drastically reduce your render time. Bump maps are not an alternative for displacement. They can be used to create fine mesh textures. The key is to understand what they do and how to use them.
