Raytrace, post processing and Photoshop tips: Creating the look of an IES light through materials

 

Here we have a simple bedroom scene where I have turned the light data to red

 

The goal is to create the look of an IES light by examining the light as it interacts with the wall.

Particulars of importance will be denoted by ALL CAPS, Photoshop will be used as my photo processor.

 

Step 1) As shown above, set your recessed lights to be a color that can be recognizable as it casts onto the adjacent walls

Step 2) Pull an elevation view and export this view AS A PNG file.

Step 3) Delete the window and add your IES image file as a "soft light" and play with the opacities in blender to create the right look.

Step 4) Crop your image to the constraint of the wall, it should look like this:

Step 5) Export your image with overlayed lights and then import as a new material into CA. click on "stretch to fit" for material sizing. The following is a very basic and unrefined representation of the final look but it illustrates the point of adding IES lights for added realism.

Notice the left wall has not been completed yet to show the difference between the two
