In this image, I wanted to create a rendering where the background context just goes away and the fixtures were in color.
I couldn’t just use the hidden line style and I didn’t want the linework to be shaded either. First, I hide the lighting components and exported the model with the hidden line style.
Then I used layers to turn off the model and just turn on the fixture components and exported this out as a .png file. Lastly, in Photoshop I simply stacked the images and used a mask to brush away any parts of the fixture image that needed to hide behind elements of the architecture.
