[Monitor221hz]

Have you tried clearing past output? And could someone post a list of all the FNIS mods they're using? As that's that only component that had major changes this version.

[qx12]

I cleaned already and The latest version of the NET file is installed.Character have animation in game,but some special animation have no effect,example dance.Additionally,ZAZ mods always likes this.

[Monitor221hz]

Please update to the latest version and retest the engine.

Is the dance animation an ofa type animation? Animations that only play on arms via FNIS animlist should be compatible now.

v1.6.1-alpha the same as in version 1.6.0 tells me "Engine launched with configuration: Skyrim SE/AE" instead of a list of registered animations. In the game itself, any sexlab animations do not start.

Same.

It sends that when the engine has started running. Did you wait for it to finish?

[mydoom13]

It displays this message immediately after start. I didn't wait very long as it used to take 6-7 seconds. but I waited about 30-40 seconds for sure.

Can you post the engine.log?

[Monitor221hz]

Alright, I found the issue. Catastrophic backtracking with the regex used to match animline. Should be fixed next version.

[mydoom13]

Engine.log Here. but there is only one entry "INFO : Skyrim Patcher 1.6.1-alpha" It seems to me that it doesn’t even start working after pressing the button Launch

[Monitor221hz]

Please test with this experimental build And let me know if the problem persists.

[Monitor221hz]

The issue was closed as the problem seems to be solved, but do let me know if the issue remains.

[mydoom13]

I pressed Launch, waited a minute and went for a walk with the dog. ) When I returned, the process was completed successfully. "Launch finished in 925.87 seconds"!! It’s not surprising that we didn’t wait until the end, deciding that it didn’t work. Previously it took 6 seconds)

[Monitor221hz]

this seems to be a separate issue; I've moved it into #255

[Monitor221hz]

@mydoom13 are you on a HDD or SSD?

[mydoom13]

@mydoom13 are you on a HDD or SSD? ssd

[mydoom13]

I gave the latest version to a friend and his animations took 974 seconds to generate. he also has ssd we have approximately the same set of mods in the game

[Monitor221hz]

@mydoom13 please send your Engine.log

[mydoom13]

Engine.log

[Monitor221hz]

@mydoom13 that's not the latest version; can you retest with v1.6.3-alpha and not v1.6.2-alpha, and then post the new engine.log?

[mydoom13]

oh sorry, I didn't see the update. I installed and launched. as long as he does his job. Apparently it's still not fast.

[mydoom13]

Engine.log Here. 1.6.3 became faster. 225 seconds

[InvIMj]

1.6.3 Works like a charm, with fast generation times. Only thing I noticed, was Let Your Hair Down's animation, makes the character T-Pose for awhile.

[TOHgoat]

still not work for me,it generates nothing.

How many seconds does Pandora take you to work? I'm on my last launch "Launch finished in 223.13 seconds" In version 1.5.1 it took me 6 seconds with the same set of mods.

[mydoom13]

still not work for me,it generates nothing.

Are you waiting long enough? this may take up to 15 minutes.

[TOHgoat]

I promise I waited for more than 15 minutes, but it still didn't generate anything, the Engine.log is empty.

About 5-6 secs*, give or take. Pretty fast overall.

Edit: 14 secs

Yeah, you have waaaaay more than me...

[MaskPlague]

For 1.5.1 generation time is 4.6 seconds with 37k animations. For 1.6.0, 1.6.1, 1.6.2, and 1.6.3, I haven't successfully run the engine once giving 20 minutes to each version and the Engine log is empty for each version. Eagerly awaiting optimization. ;-;
