Well spotted! The SGI tessellator is the de facto standard, so we should really handle this bug. Although a list of (weight, property) pairs might really be better, I am extremely reluctant to change the API, but it turns out that we don't have to: We *have* a default value, namely the first vertex passed to the combiner. This is never NULL and the weights for the NULL vertices are always zero, so we can happily use this. A corresponding patch has been committed. Cheers, S.
