LodMesh polygon limit?

What is the polygon limit of a LodMesh in Unreal Engine 1, if any? I'm just curious, since it appears that the Horizon engine supports only a pathetic 64 polygons per model and anything more must be split into several meshes... And it was created about 1998 too...

Judging by the headers the maximum possible is 2^32/2 {2147483648}
Code: Select all
// LOD-specific objects.
// Make lazy arrays where useful.
TArray CollapsePointThus; // Lod-collapse single-linked list for points.
TArray FaceLevel; // Minimum lod-level indicator for each face.
TArray Faces; // Faces
TArray CollapseWedgeThus; // Lod-collapse single-linked list for the wedges.
TArray Wedges; // 'Hoppe-style' textured vertices.
TArray Materials; // Materials
TArray SpecialFaces; // Invisible special-coordinate faces.
// Misc Internal.
INT ModelVerts; // Number of 'visible' vertices.
INT SpecialVerts; // Number of 'invisible' (special attachment) vertices.
Of course the renderer probably would fail long before that many..

Hmm, interesting, so that means you can create as high-poly models as you wish... That+proper collision opens possibilities...
Though it would be interesting to see how many polygons each renderer supports.

A few UT2k4 models is enough to notice the slowdown. I'd say 1/4th of a UT2k4 model is as high as you'd want to go.
UT3 models slows unreal down to a crawl.

That's interesting, is there a reason for that? UT3 models in UT2004 don't seem to have that much of effect on performance.

UT3 rocket launcher and Linkgun models don't slow me down in Unreal at all o.o

Doesn't UT3 lag on a P4 as well?
