In Inventor 2016 we had a change of rendering engine in the Inventor Studio environment.  It was changed to RapidRT.

There was also a change in the way that the lighting styles are used.  Inventor Studio now uses IBL ( Image Based Lighting).  This visual effect is now more consistent with the realistic visual style you see when you are in the normal modelling environment.

Let’s take a look at what type of lights you can create in the Inventor Studio environment.


Directional Light

The Directional light type will emit parallel beams of light in one direction emanating from a light source that is an infinite distance away. Something like the sun.

When creating the directional light you will see that there are 3 tabs. General,Illumination and directional.

The General tab allows you to choose a target and position how far away the light will be from the target.  The flip buttons will switch the target and position if needed.  You can also switch the light on or off.

The Illumination tab allows you to change the intensity of the light as well as the colour.


The directional tab allows you to change the angle of the light in both the longitude and latitude direction.

Point Light

The Point light emits light in all directions from a single point.  Something like a light bulb.


When creating a point light you also have the 3 tabs General, Illumination and Point.

The General and illumination tabs are the same as the Directional light.  The Point light allows you to change the position of the light with respect to the origin of the assembly.


Spot Light

The Spot light emits a conical light from a single point.

Once again the General and Illumination tabs have the same functionality as the 2 previous lights.


The Spot tab allows you to put in the x,y and z co-ordinates of the position and target.

The hotspot specifies the angle of the spotlight. This range of the angle is from 1 to 150 degrees.

The falloff specifies the falloff angle of the spotlight. This also ranges from 1 to 150 degrees.
