With what we get being a fairly plain looking low light effect that quite frankly doesn't look all that impressive, seeing as we also appear to be getting some very sharp CG looking edges to our shadows. After which we can then position those inside the camera view, and take a render.
Now we do create this light type a little differently than some of the others, in that we need to left click, and drag in the front viewport in order to set the position of both the IAS light object itself and its target taking care of course, not to place the light inside any of the scene geometry if possible. And then after coming over to the V-Ray toolbar, clicking to select the IES option. As we have with previous lights, then let's add an IES light to our scene by first of all, jumping into a quiet view. And so potential, extra realism to a scene. Therefore we first had to calculate a preview and measure the maximum brightness, adjust the light intensity and finally calculate the image.- When creating both interior and exterior renders, and perhaps especially Seoul for visualization pieces that we may be creating, the V-Ray IES light offers an extremely powerful, and easy to use method for adding real world lighting data. The goal was that the preview images should have more or less the same brightness. We then calculated this scene automatically for each IES file using python. After this process, there was "only" 160'000 data left.Īfter that we created a scene in Blender, where a light source hangs 5cm in front of a wall and 1m above the floor. Using python we read the data, hashed the content as MD5 and assigned the data to the individual manufacturers. We have enriched existing IES collections with manufacturer data and have reached almost 200'000 data in the end. However, it is cumbersome to find the correct file using try and error, as the manufacturer does not necessarily include a visual example.įor this reason this page was created.
This data is provided by many manufacturers so that lighting designers can realistically simulate how a project will look when a specific light source is used.ģD artists also use this data to calculate their images more realistically. IES files describe how light from a lamp is distributed in a room.
