Fuzzy Distorted Fabric Render

If after rendering with Vray your render looks fuzzy, bumpy, spiky or some other appearance of a visual glitch, the issue may be that your fabric's displacement depth is set high. if you are uploading to Stylezone with a quality standard, this may be a Vray render.

3D fabric texture is made up of material maps. One of the material maps, displacement, cannot be seen in the 3D window, only in a Vray render or Vray preview. A displacement map represents the 3D texture and thickness of the material, and is used to create realistic depth effects. This map is most useful in materials with strong textures that cannot be shown with only a normal map. When in use, the displacement depth is low. If the depth is accidentally set to a high value when not needed, an extreme over representation of the fabrics texture will be seen in Vray renders. 

To check if this may be the issue, select your fabric and view the material maps in the right side content menu. Scroll down to the displacement map. If you see the depth slider set all the way to the right, this is likely too high. If your fabric has average or subtle texture, set the depth to 0. If you are using multiple fabrics in your garment be sure to check all displacement map depths are set to 0. 

 If the fabric has strong texture, you can test lower values to see if your fabric benefits from this map. Adjust the value to be towards the left but not at zero, then click the Vray preview icon to preview the render. Allow the preview to load until you can more clearly see the result. If the texture is still too high, lower the depth. If the map does not add to the visual effect of the garment, set the map to 0.
