IES Light

[marceloroca]

I want to create the same scene with IES light from the maya demo:

https://radeon-pro.github.io/RadeonProRenderDocs/en/plugins/maya/photometric_light.html?highlight=ies

The parameters I'm using are:

• IESLightSetImageFromIESdata = (ies file), 255, 255
• IESLightSetRadiantPower3f = 2, 2, 2

The image in maya is this:

and when I render in RPR I get this:

I don't understand what parameters and values I need to use to have the same light spread

Thanks,

As light is softer in original image I feel that this is a post process difference, ( like gamma correction, or exposure ).
