Hi,
In such scenario, adding a
Linear 1S Generator to your style to handle borders "separately" would be the recommendable way.
Generally, clipping is an issue. We've been asked about it before and we did actually implement a solution in a previous release but unfortunately, it had to be removed because it could not be correctly UV mapped. Unfortunately, this was a limitation of the Max SDK. In some cases, you might find handy the
VRayDistanceTex map to perform a render-time boolean and a capping effect in a very similar way as
explained in this post.
Hope that helps.
Best regards,
