Feature suggestion--add one option to use C4D native gradient as quad_light color directly

Hi dear 

we usually render 3d products, and the quad light with gradient color is very frequent and helpful. 

 

in Arnold's current workflow, we have to create a material with the ramp node first, then apply this material to Quad light color. but if we have many gradient lights and materials in the same scene, the current workflow will be inefficient.

 

it will be great if you could add one option on the light color field to use the C4D native gradient directly. I know octane render has this feature 

 

here I attached a screenshot, please kindly check it. thanks

Not an answer to your question but  I wasn't aware you could do this. What kind of material do you apply to a light to make the light have a gradient? I tried it with a random surface and also toon shader with a gradient ramp but the light color didnt change. is there a specific material you use that is made for lights?

Is supporting the native gradient relevant here, or just adding a 'gradient' option to the list is the important bit? I'm thinking of creating a ramp shader and linking to the light color directly from the menu. How's that sound?

Hi dear 

Please check the attached ScreenFlow, it's very simple and efficient to create and adjust the gradient light in Octane.  

I think it will be good enough if make a similar feature in Arnold

Right now Arnold quad_light color only supports constant color, texture, and material,

but octane light color supports a lot of shaders,

so better make Arnold quad_light support gradient shader.

yea it's good if you add a ramp shader to the light color directly from the light color menu
