hi Dave,
unfortunately that didn't work, because the conversion algorithm still had to process all indices.In that case, a quick fix might be to save out the primitives from fluxus, as they should be quicker to load back in once processed this way.
i optimized the loading a bit by merging the vector loading and storing the unified index per face vertex. on a 1 megabyte obj file, the loading time dropped from 5.6 seconds to 2.1, which is still too slow.
best, gabor
