What is lighter DTS or DIF?

#1 DIF is really just designed for convex objects--it's not merely an alternative file format. If an object is naturally convex, it should be best to use DIF.

On the other hand, I'm using the polysoup collision code, and I got a VERY significant performance boost moving from DIF to DTS. On the other other hand, my DIF's were not naturally convex objects, and certainly I wasn't using it in the envisioned way, so YMMV.

It probably comes down to what you're using them for.

#2 Im modeling a School, and the responsables for the objects exported everything as DIF, and im thinking it is a little heavy. And someone said to me that portals dont occlude DIFs, only DTSs, so thats why i wana know.

#3 DIF's are the things that can actually be portaled. You create a portal brush to work with the renderer.

Both DIF and DTS models can have level-of-detail, however, to provide the renderer optimized information.

#4 Can you explain better the thing about criating the portal brush to work with the render? because i have a school with portals, and separated objects as dif with no portal on them, is it right ?

#5 This will help explain it.

#6 > Static Mesh imported in constructor and exported as DIF

i think you're referring to constructor's ability to bake DTS objects into DIFs,
which requires TGE 1.5+, i believe.

i may be wrong and/or the situation may have changed,
but last i heard there was a significant performance penalty for such DTSs,
and from a performance perspective you'd be better off to model the building as a DIF and keep the DTSs as DTSs. i would love to be corrected on that tho, as it's a great feature otherwise.

#7 Orion Elenzil,

This is the case, do you remmember where did you read that?

#8 I thought it was in a dev-snapshot,
but i don't see it in this one,

hm, i can't find it.
