Vray shadow linking Dome ligh and meshlight

[pizzaia]

I've been trying to break the shadow link of a meshlight and a dome light to some object but without success. Works with vray rectangular lights though.
Is there any way to avoid an object to cast shadows of a specific light?

thank you,

It should work fine or at least it does on our end. For the dome light, it's pretty straight-forward. For meshLights, however, there's a slight catch - you need to break links between a node called vrayLightMeshProperties_lightlink and the object, and not the vrayLightMeshProperties set node. Could you check again and let us know if it works this way, please?

The Meshlight trick worked! I think that my issue is something else, that's why I thought the dome shadow linking was not working, that might be fixable though. I was hoping that the light linking would also work on the reflections of the object, instead will reflect whatever is around. Is there a way to override the reflections of an object to a dome light? I tried using vray material override and plug the dome texture into the environment override without success. Basically I need an object to reflect just that dome, lit by just that dome and shadowed by just that dome, everything else can be as it is.

thank you for the help

Yes. The easier way would be to just disable "affect reflections" for the dome light, but that affect all objects in the scene.

The other way would be to add a VOP (VRayObjectProperties) node to the object. Look for the "Exclude lists" rollout in the VOP node. Enable "Use reflection exclude list" - this will create a new set in the outliner. Just add the dome light as a member of this set. This way, the dome light's reflections will be excluded from the reflections of the object that has the VOP node.

Will this work for you?

That's perfect! Thank you so much for the help!
