Title says it all! Using a toon material.

Hi,

This is a known issue and our developers have been notified. Kindly note that once a solution has been devised, it will be implemented in one of the future update releases.

Unfortunately, a temporary workaround cannot be recommended apart from rearranging the lights' positions.

any progress here..?
invisble lights are still breaking the toon lines...

Kindly note that the behavior of this particular workflow will be optimized in the next major update.

In the meantime, as a temporary workaround, you could use non-geometric V-Ray lights (such as V-Ray SpotLight, IES, or OmniLight)
