Spot Light

V-Ray for Maya V-Ray for Maya :: General
1

Hi
This has bothered me for quite a while now but the Maya spot lights don’t seem to work like in Maya software or mental ray.
For example it is difficult to have a smooth fall off.
I would usually use the Penumbra angle to soften the edge of the lit area but for some reason if I also use the drop off, I end up with an hard edge again. In some case the Penumbra angle doesn’t even seem to work.

I am doing something wrong or are people have the same issue?

Thanks,

Yannick

Anyone?
Am I the only one that found the spot light to be too sharp?

After some test it seems that the penumbra option doesn’t give the smooth transition, you would get in Maya Software or MR.

It works fine here.
Could you please attache some screenshots? Which V-Ray for Maya version are you using?

Hi Zdravko,

See attached image and file.
The sharp edge happen if I have a physical camera attached.
Thanks.

Hi Zdravko,

I am using:
V-Ray: V-Ray for Maya version 2.00.04 from Jul 4 2011, 16:16:51
V-Ray: V-Ray core version is 2.00.01

So when you rendered the file I provided, you didn’t get the hard edge?

Thanks,

Yannick

Can you reproduce the issue with the official build from our website (28 Apr) or with the latest nightly?

It is difficult for me to test it as I am in production at the moment.

I see.
Try to add Lights Attributes (Attributes>VRay) to the Spot Light and set the Cutoff Threshold to 0.

Hi Zdravko,

I tried your suggestion but it didn’t change anything.

Thanks,

Yannick
