Real IES 3: Better. Faster. Brighter

Give light

to your 3D renders

Since 2015, Real IES is the professional solution in photometric file creation.
With this standalone software you can create your custom photometric file easily and in few seconds. Real IES generates files compatible with a wide range of 3D rendering softwares. Being CG artists ourselves, we developed Real IES keeping in mind how time-consuming is to find proper IES files for a 3D render.

Intuitive user interface

Real IES 3 with some new features added, we opted for a slight redesign of UI and general usability improvements

Real IES parameters

Immediate feedback, keyboard input, recommended maximum values.


Light quality is guaranteed by photometric data visually generated according to your creative necessities.

Inspector toggle

Extra grid overlay and additional information about your light.


Real IES can generate a practically unlimited amount of random photometric files.

Take care of your project

Real Save your .ies file, edit it later, insert your name into the ‘Manufacturer” field.


For theoretical data extraction and for interior design and photorealistic 3D rendering.

Lighting fixture details

Input the height, luminous flux and power of your light or use default parameters.

Real IES C0 C90

Asymmetric lightcone

C0-180 and C90-270 planes

With Real IES 3 you can now create asymmetric light cones by adjusting separately the intensities for C0-180 and C90-270 planes. If you need a symmetric light instead, just leave the values in one of the tabs blank and the saved photometric file will be symmetric by default.

Real IES lightgraph


precise polar diagram

The LightGraph tab (new in Real IES 3) offers a proportional photometric polar diagram of the photometric light while being created. The yellow color of the line corresponds to C0-180 plane, while the blue one represents the C90-270 plane.

Real IES snapshots


to use inside Real IES and to export

In the Snapshots tab you can store in temporary memory up to three different snapshots, capturing the light cone and the light parameters corresponding to it. Starting from Real IES 3 you can export your IES as a rasterized 32-bit .exr file.

Per-user license

to install Real IES everywhere

We developed our own licensing system that keeps care of your purchase. With one license you can use your copy of Real IES everywhere and activate it on one machine per calendar day. Those who own a copy for Real IES 2 are eligible to free upgrade to Real IES 3 and will get all the instructions via email used for the previous purchase.

Real IES lightlist


complete intensities’ overview

In the LightList tab (new in Real IES 3) you can see the exact intensity values for all the angles, both the ones that you have on the sliders and the intermediate ones, for C0-180 and C90-270 photometric planes.


for those who want to “spice it up”

The LightSpikes slider (new in Real IES 3) on the top of the LightGraph tab, allows you to manipulate the intensity values of the angles “between the sliders”. This way you can create more artistic photometric lights with sharper borders within the light cone.
