Lag with HDT ?

[Mimolette27]

Hello everybody, today is restarted skyrim with mod, after like 3 hours of play i get massive lag(drop to 5~0fps) when i'm looking at woman and it's seem like it's a problem with HDT bounces and jiggles.

 

I use the HDT sevenbase body available on B&J Nexus page and conversion of Epic Elves, Succubus and temptress race.

 

THX for your help.

 

Ps: Sorry for my bad english ^^

Are you using HDT PE or HDT SMP? 

 

HDT SMP is still in alpha and issues with CPU load is probably expected. 

 

If you are experiencing this with HDT PE, check the skeleton first and body mod second.  Try the latest XPMSE (here or Nexus).  If you are still experiencing lag, post more specifics (what HDT PE mod (body, hair, skirt, accessory etc), which HDT PE xml so people can help.

I'm using HDT PE, what did you mean by Check skeleton first and body mod second ? i'm pretty low with HDT modding.

Which skeleton mod are you using?  Older skeletons are not suitable for HDT PE.

 I'm using XPMSE 2.75 (maybe i failed something when it's ask me what havok i want to install ?)

 

BTW thanks for helping me

I just noticed you are using race mods.  Race mods have their own skeleton so that might be an issue.  Most of the time you can fix it just be replacing their skeleton with the one from XPMSE.   Race mods can be tricky.  You can try without using custom races and see if still getting drop frames.

[Mimolette27]

I check that and only one race (not used yet) use a differente skeleton, can that be the cause of the problem ?

[zzz72w3r]

As for Havok, just leave it the way Groovtama has it.

Which race? 

 

If no character (player/NPC) is using that race then it's probably not the cause but I am not knowledgeable of custom races. 
 

[Mimolette27]

The succubus one and i don't think any npc use it.

Are you using ECE?

[Mimolette27]

Nope

 

[zzz72w3r]

Where did you get the xml file? 

 

Try get it from here: http://www.loverslab.com/topic/27122-working-vagina-hdt-collisions-hair-physics-now-with-belly-support/

[Mimolette27]

For HDT PE the original one and for HDT B&J belly the original one too.

 

(I'm using a sevenbase body, if i use the xml from the post you give to me, no problem will happen ?)

 

[zzz72w3r]

I don't use 7base and I don't know the HDT B&J belly.  The only belly node bodies with HDT support are the Bodyslide version of CBBE and UUNP (has a 7base shape).

FAQ  #5 from the XPMSE page:

 

"

5. How 2 fix low FPS or broken HDT Physics after updating to 2.0+:

Spoiler

HDT is logging a tremendous amount of error which means the default HDT xml has content that one or more actors skeleton does not support. Keep in mind to replace custom races\actors' skeletons propertly.

Also check your xml for old problematic content, like "NPC PreBelly" and "Weapon" nodes like "WeaponSword"

That stuff is old and not supported.

Belly node was a mess with HDT so now if you want belly in UNP you better switch to UUNP.

[Mimolette27]

I will try to replace the defaultBBP XML by the one you giving me and i will see

I have custom actor i will try to replace her skeleton thx for the tips

 

Not using a belly can fix my problem ?

 

[zzz72w3r]

Belly node pre-UUNP, pre-XPMSE was almost always the problem. 

 

CBBE/UUNP +XPMSE + xml-post-XPMSE = peace of mind.

[Mimolette27]

I think i will just not use hdt (Too bad for me)

Thx for help

I had a similar issue with bounce and jiggles. The mod supplies the body and the xml file, and when I used them I got noticeable lag wherever there were more than a handful of female NPCs. This was with the latest XPMSE.

 

My set-up now seems very stable.

 

XPMSE 2.75

HDT-PE 14.28

xml from "My Body Is Not Jello"

Body is Seamless Body UNP by zzjay (from Nexus) which I added the belly, left breast, right breast, left butt and right butt bones to using Outfit Studio. I'm not great with bodyslide at all, but I generated the UUNP HDT UNP template body and used that as the reference to copy the weights to the Seamless body. I preferred that result to the UUNP body itself.
