Optimized Meshes

[lynx101]

I'm trying a few things to improve my frame rate overall, specially in the overworld. I have been looking at some mods that replace meshes with optimized versions, to reduce GPU load.

The three mods of note are...

 

Optimized Qarl Texture Pack Meshes

Optimized OOO 133 Meshes

PYFFI Optimized QTP3 Meshes - Fixed

http://www.tesnexus.com/downloads/file.php?id=26756

 

I have the following addons of note, installed:

All DLC

UOP 3.2.0

USIP 1.4.0

UOMP 1.5

UOP Supplemental 3.2.6

OOO 1.33

Qarl TP 3 + Patch 1.3

QTP3 Redimized + Patch

Operation Optimization 1.1.1

 

I am wondering if anyone has knowledge of what effects these will have on my game world, visuals and whether the models will seem overly reduced in complexity.

Also what of these three do I need (if any at all)?

Thanks

I think you need none of them. just google for pyfii download it and install it (provided you have python installed already) and optimize the meshes yourself. sure, it takes a LOT of time, but i think it helps you grasp somehow what is really wrong with oblivion meshes. and more importantly what moders to trust and what not. for my experience i can tell you that francesco's and Oscuro's meshes are some of the cleanest meshes out there. and CUORP, Unique Landscapes, Apachii Goddess Store, and vanilla meshes are the dirtiest i've cleaned so far.

 

just remember to only use it on static meshes. those that have any animation embedded. not that it would cripple it, but they will just lose any animation they previously had

Thanks for the tip Vile, I'll give it a go.

What exactly is happening with the optimizations? Are excessive polygons being removed without noticeable drop in shape and definition, or is junk overhead data being removed?

 

And a quick addition, I have setup PyFFI ready to go (5333 nifs 926.93, this will take a while heh), Just wondering how I can make sure it doesn't optimize objects with animations?

The readme says:

6 - Start radio is enabled allowing you to start optimizing. All files will be processed with the following parameters:

"python.exe Scripts\niftoaster.py optimize --noninteractive <NifFile to be processed>"

 

I'll take a guess and say, the -noninteractive parameter means don't do animated meshes?

most of the dirty meshes come from the 3dsmax nif exporter. why is that? well, i'll try not to get longwinded: when you model a mesh with 3dsmax it makes lower definition versions of it to use as it's own lod mesh (to optimize rendering of distant objects) problem is they're embedded to the main mesh. and as such oblivion does not use that functionality. so if you've got a big, complex mesh (such as the cludtop temple) chances are the exported version has several thousands of unused polygons, which translate in several megabytes of junk data. and most importantly drastically fewer frames per seconds in game due to the engine having to process all that junk. that's most of the problems.... the other problems involve careless modeling, for instance in CURP there are a couple meshes from which i cut down almost 50000 vertex each! one is a sort of arabian temple or palace (all carved from a single mesh!) and the other is a sort of house made out of logs (the ones floating near leyawiin), the guy just started copying logs, one next to the other one, resulting an insane ammount of redundant data.

 

as for what can you do to avoid optimizing animated meshes? well, what i did was to pyfii everything! then check the meshes for odd or missing features.and then restoring that from a backup. but then again, that may not be your cup of tea, i have a 1 terabyte of hard disk to spare. but if you don't i warn you: it does take a fair ammount of space.

 

or you could pyfii one mesh at a time, but that will last till one day after judgement day, so it's your call.

 

too bad i have not found a way to further automate pyfii optimizations.
