Python | Light Values: Intensity (Luminous) and Temperature (Kelvin)

5inch — Tue, 14 Dec 2021 09:41:06 GMT

Hi Vred Pros,

brief and simple question I guess?

In Vred Pro 2022.1,

I need to edit Light Values: Intensity (Luminous) and Temperature (Kelvin).

I tried:

light = getSelectedNode()

temperatureValue = vrFieldAccess(light.fields().setReal32("intensity", 123.456))

temperatureValue = vrFieldAccess(light.fields().setUInt16("temperature", 5000))

but this seems not to work.

Can you please drop a tip for me.

Many thanks,

Best regards!

You can´t really access this with the old python interface since that is very low level and just gives you the internally stored values. You should use the new python interface for this, the vrdBaseLightNode should provide all you need:

file:///C:/Program%20Files/Autodesk/VREDPro-14.1/doc/v2/class_vrdBaseLightNode.html#vredvrdbaselightnode-getintensity

So simple something like this should do what you want:

pointLight = vrNodeService.findNode("point light") pointLight.setLightUnit(vrLightTypes.Unit.Lumen) pointLight.setIntensity(500.0) pointLight.setUseLightTemperature(true) pointLight.setTemperature(4000)
