Re: hiccupping for new objects/textures

[Keith W. <kw...@cs...>]

No, we (the group) settled this a few weeks ago.  Someone (or multiple
someones) told me that the number of unique trimeshes that are submitted
definitely matters.  I subsequently verified that this is definitely true.
Take a given scene with a number of redundant objects (with varying
translation, scale, rotation, whatever) and render it as a set of
individual objects.  Then do the same but first union all the objects into
a single huge trimesh.  The second method renders much faster, between 2
and 8 times faster in my experience.
