Plissé effects can be created using one of the following methods:
Add plissé effects using iron lines. This is more suitable for larger and more regular plissé creases.
Add internal lines for the creases.
Apply the Iron property to the internal lines. Experiment with values between 0-180 degrees to achieve the results you want.
Lower the grid size to better simulate the creases. (Lower grid size means more details.)
Adjust drape using the 3D Styling tools.
Add plissé effects using depth maps like normal and displacement maps. This is more suitable for smaller or more irregular plissé creases.
Create a normal and displacement map in external image-editing software like Photoshop.
A displacement map should be a striped image with different shades of gray to create different heights for the creases.
Displacement map effect can only be seen with ray trace rendering.
Use the image editor to adjust the size of the plissé and use the V-Ray preview feature to gauge the size and depth values for the map.
