Can we load in a texture map onto a UE4 rect Light? Tweet

[andrewmartis]

Hi all,

Is it possible to load a texture into the 'source texture' slot on a UE4 RectLight and have that transfer into octane. I have been trying to map an HDR texture, a softbox image, onto a rect light and it seems that the texture has no effect. The light color of the Rect light is still controlled by the 'light color' slot in UE4, the texture doesn't seem to work.

As a workaround I have created a emmisive material with the image and mapped to a plane but these planes start to interfere with the camera, either by blocking the camera when they are placed between the camera and the object, or creeping into the background where you see the light behind the object (not so much of a problem because I will replace the backgound later).

Can I hide an emissive plane from the camera while still keeping emission, is there a way to get the properties of a rect light with the emissive material setup?

Cheers
