My displacement has huge spikes or is invisible!

Too pronounced or barely visible displacement in rendering, may indicate wrong displacement settings in your Corona material or in Render settings. Make sure that:

• Displacement's min/max level values in your material correspond to scene units you are using (i. e. the value is not too high nor too low in relation to the object's size)
  
  
  
  
  
  
  
• Displacement's "Water level" value is set to 0
  
  
  
  
  
  
  
• In Render setup > Common tab under "options" section, the "displacement" checkbox is checked
