Cap lighting values on Viewport 2.0

[snivlem]

Hi,

I'm not sure if this has been added in 3.0, but would it possible to have the V-Ray light values capped in the viewport?

Currently, when the scene is using lights are using real world values - the viewport becomes 100% white.
Obviously we can just work with default lighting, but the problem happens with the batch render hardware 2.0.

No matter the options that are selected, Maya seems to turn on the lights creating a 100% white output.
The only way to fix is to use the default Maya material which seems to turn off V-Ray lights but we get the lambert output which kind of defeats the purpose of it.

Thanks.

Is there not an exposure slider in the viewport now?

Best regards,

Yep, but only 2014.5 SAP, 2015. The best way is probably to read the exposure from the camera and automatically correct the values. But it will take a while to implement it.

Thanks for the reply.

The exposure slide is not obvious to me anywhere in Maya 2015 - I'll see if I can find any references to it in the maya docs.

Ivaylo, that would be a elegant way to handle it indeed. Thanks for the help.

AFAIK, the exposure setting is only in the Render View which is not very convenient. The viewport itself can work with floating point, so there is no problem to support exposure directly. But Autodesk seems to missed that.

Vlado remembered the 2015 SAP presentation. The controls are only there:

Great! Thanks for taking the time to post that.

That should play nicely with V-Ray and photometric lighting with the batch hardware renderer 2.0.
