VRAY Sphere lights?

[CEJ1976]

Hi,

 

I have a couple of quuestions regarding VRAY sphere lights:

 

1) I am using a VRAY sphere light to simulate a glow around a light source. However, I cant seem to make the edge of the shadow cast by these lights to be soft? Does anyone know how I amend the softness of the shadows. (please see Sphere lgt settings)

 

2) I am using the VRAY Extratex render element for my AO passes, however I am getting some strange results around the VRAY Sphere lights. Please see example of the render elements. Does anyone know how to exclude the light shadows from my AO passes?

 

Does anyone know the answers to these 2 questions please?

 

Thanks very much

You're using the wrong tool for the job. Do a glow in post.

I am using the VRAY sphere light to 'light' the area around the light objects, but the shadows these lights are casting have a crisp edge to them, whereas I want them to have a soft edge??

 

any ideas please?

The sharpness of shadows with Vray sphere lights is directly related to their size. As in real life a small light source will cast sharp shadows while a large light source will cast softer shadows. If you can't increase the sphere size for whatever reason I suggest using a standard light type such as omni instead.

There could be two reasons for this: a) size of Vray light or b) its intensity. Vray sphere light scatters rays in a specific way that might not be suitable for large spaces like the one you have there. Try lowering light intensity drastically to see if the problem goes away. You don't necessarily need to use this type of light to get ambient lighting.
