LS Processing percent goes down?

fernando-1 · November 8th, 2003

Why do sometimes my solution processing percentage begins to go down instead of increasing and I start getting an orage glow on my image? It happens on certain projects.

This happens when you have coinciding faces in your scene. Symtoms are iterations that go down to zero and overexposed scenes. This happens becuase the surfaces that are coinciding contribute indirect lighting twice. You could have many coinciding faces, but I'd check the largest ones first.

Of all the little bugs that remain in Lightscape, that one bothers me the most. A perfect model would be great, if such a thing existed. I know mine are never perfect, far from it. Who has the time to creat a 100% LS-ready model? Certainly no-one who does real projects in the arch-vis market.

So close, and yet no way to get there...thanks Autodesk, you screwed me again.

When you say "coinciding" you mean on the same plane? Please detail. Solution?
Thanks.

Coinciding means two faces on the same plane. It typically happens during an import or conversion from another software, or done accidentially in your modelling program when you copy or clone elements. The solution is to got though your model and make sure that there are no coincising faces. If you can't find them in the original model, go through the LP file deleting one face at a time and undoing it (if required) until you find the ones that are duplicated.
