QUESTION


How can I make my fireplace appear to be glowing and casting light around my room?

 


ANSWER


In this article we will be adding a light to our fireplace to give off a realistic, glowing, fireplace effect for our ray traces.

First click File> Open Plan... and choose a file that has a fireplace.

 

Tip: For more information on how to model a custom fireplace or use the fireplace tool see the following articles in this online Help Database.

Article Number 58: How to create a custom chimney and fireplace
Article Number 331: How to use the Fireplace tool.

 

 

Creating the "Glowing Flame" effect

  1. Open a 3D view of your fireplace by clicking 3D> Create Perspective View> Full Camera  and drawing a Full Camera that faces your fireplace.


  2. Click on the Adjust Material Definition  button and click on the flame material to bring up the Define Material dialog.

    Note: If the flame material is behind a glass panel or other obstacle you can click on the Delete Surfaces tool and then click on the glass panel to temporarily hide it while you modify the fire.


  3. Under the Properties tab of the Define Material dialog, increase the Emissive property. You can increase this to your preference and click OK.



The flame should now appear to be glowing.

 

Creating the lighting for the rest of the room

  1. From the Floor Plan view, click 3D> Lighting> Add Lights .




  2. Click in front of the fireplace and drag to draw a Spot Light facing away from the fireplace.




  3. Use the Select Objects  tool to select the light source, then click Open Object  to bring up the Light Specification dialog.


  4. On the General tab specify the Height off the floor.




  5. On the Light Data tab change the Cut Off Angle to 180° and the Drop Off Rate to 12.0.




  6. Now change the color to better match the flame and change the intensity to 500 Lumens or 40W.

Your room will now be lit by the spotlight in front of the fireplace and appear as though the light is coming from the fire.
