Does anyone know how to do this with Octane in Houdini? https://youtu.be/wsHO23Af3TE?t=1955 [youtu.be]
Basically controlling a light shape with a texture, I know there are IES textures but it would be nicer to to edit it quickly using a ramp.

Octane is a physically based renderer, it doesn't make sense to control light falloff artistically.

Never used it but it could be a solution:

Thanks for the suggestion, I checked it out but it's not really what I'm looking for. Although it does give me some ideas.

Sorry I didn't explain myself properly, I'm not trying to control the falloff from the light I'm trying to control the shape of the light with a ramp or gradient parameter so it gets darker towards the edge of the surface. From my research it seems to be a legit workflow in C4D for product lighting. Is there a reason it would be bad practice?
I guess I could use a mesh with an attribute or texture to control the emissive channel but the octane spectron lights are supposed to be better and faster.

I misunderstood your request. Would a spotlight work?
Edit:
Spectron sounds like the ticket. I'm not sure of the status of their implementation in the Houdini plugin though.
