KSP 1.8.1 RO - "Voxel CrossSection Area is NaN" #103

Open scouarn opened 3 years ago

scouarn commented 3 years ago

Hello [edit : a lot of wrong stuff about the issue].

I get this kind of log message. [edit : some other wrong stuff]

[LOG 18:49:16.371] [FAR v0.16.0.1]: Voxelization Time (ms): 59 [LOG 18:49:40.872] [FAR v0.16.0.1]: Updating Untitled Space Craft [LOG 18:49:40.874] [FAR v0.16.0.1]: Overall bounds error in Radial Tank (Integral) 0 meshes [LOG 18:49:40.939] [FAR v0.16.0.1]: Voxel Element CrossSection Area: NaN FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 0 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 1 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 2 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 3 . . . FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 164 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 165 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 166 FAR VOXEL ERROR: Voxel CrossSection Area is NaN at section 167 Std dev for smoothing: NaN voxel total vol: 8.30664434111419 filled vol: NaN

I don't really know if this is the problem comes from the parts models, the voxelization algorithm or my game/pc config (I am also not a ksp mod dev). For the moment I'll try to play without the mod, thanks for reading, hope to be useful.

Seems like an error in voxelization on FAR end, I'll have a look in the next few days.

Thanks for the quick answer and merry christmas !

Hello again, I weirdly fixed my problem. I found out my game was crashing because I had left the force-opengl flag on, maybe a glitch from unity or my new gpu...

However the long message kept randomly showing up in the debug console (not at all "in a loop" like I initially mentionned, I guess I missread the logs), not always consistent with the parts attached to the craft (and even stock ones). It may be related to a KeyNotFoundException I noticed from FAR. It also sometimes caused a lot of NaN errors when doing AoA swipes.

I messed around a lot trying to reproduce the issue but it gradually stopped occurring, even after restarting the game. So I ended up deleting all the generated config and cache files and it then only happened once. It's still working fine after repasting the config files I had backed up.

So I guess it's "fixed" but not "solved". I'll be keeping an eye on the console.

@scouarn I was flummoxed by this... I tried adding -soft to a shortcut target and it seems to have restored FAR voxelization. Thanks! Sucks, though...it would save my CPU some blisters and calluses if I could let the GPU handle some of the graphics side (i have a suite of graphics mods installed). Then again, this game is terrible at multi-threading, and it seems to run well enough on the opening screen and in the hangar...gotta try loading a high-part-count model tomorrow to be sure though.

Heck, even if it lags a bit, I'd prefer it to flying in the souposphere...

I'm getting the same issue even down to the fact that forcing software rendering doesn't completely fix it. It works, but reliability isn't fantastic. Great.

Did you ever figure this out? I still get issues with voxelization.

I assume your issue was when attaching a previously unattached part to the ship in the editor. This should fix it.
