Octane lights cast a shadow from Toon lights even if the Cast shadows checkbox is unchecked.

Hi Paride,
anyway to have octane lights brighter. The cloud on the right is 100 meters by 100 and the octane light is like 10 meters We want to place it inside like a lightning. Other any other ways to do it to have brighter light. For some reason volume emission does not work are there good ways to make clouds light up Thank you

Hi coilbook,
I think best solution is to use texture emission, to use volume emitter you need your sim has emission values in vdb. My advice is to put multiple emisison textures and different geometric shapes inside the cloud.

Hi RicoUk,
toon material works with toonlights.

Hi Paride. Yes indeed, what I was meaning is that an Octane light will cause a Toon light to cast shadows. I've attached a still to help to explain.

Hi Rico_Uk,
Cast shadow option does not work with toon material; as you can see using diffuse material (A) cast shadow works fine, but not using toon material (B).

What I'm trying to do is have toon materials and toon lights in the same scene as octane materials and octane lights, and I don't want the octane lights to cast shadows onto the toon material (as shown in the image in my last post where the rectangular shadow from the octane light can be seen on the surface of the toon material object).

Hi Rico_uK,
I advise you to use geometry with emission texture node, set opacity 0.

Thank you that's a good tip!
