Well, I had this error previously only with my Character and only in 1-2 isolated interiors, but now, I beleive because of using Dynavision 3, I`m having such an issue here and there, mostly in Underground Hideout.

PC and NPC just turns invisible, when entering a certain spot, like they got overriden by filter or a ligthning effect. I still can see their shade and they are 100% accessable, can talk with them, they are located on the radar and on the minimap. Just their 3D model is invisible.

Also after loading a new game for some time everthing is ok.

I know there was a similar topic invisible parts bug, but its for ENB, not Dynavision.

I beleive I can manage it myself, but if anyone had such problem or can suggest a faster solution, you`re welcome.

Update:

Found a temporary solution, will test further.

Whatever Dynavision is adding, it messes the lighting and unlike ENB, has no means to configure transparency. Made some test runs with basic ENB 0.249 and transparencyfix=false, everything works correctly.

When I`ll find a way to fix it withoug ENB, I`ll update this topic.

Sorry i didn't see this sooner,

The transparency bug in Dynavision is a well known problem with the mod and Dof in general on this engine.

ENBs transparency bug is a different fixable issue: http://vgunetwork.forumotion.net/t158-weird-random-invisible-glitch-face-armor-weapon-parts-randomly

I doubt this can be fixed without knowing exactly what order image space modifiers and shaders are loaded and how they interact with each other, even then it might not be possible.

The only thing i can think of is trying this: http://www.nexusmods.com/newvegas/mods/49420/?

Its an old fix for enb but it might have en effect on Dynavision as well.

I hope this helps and sorry i couldn't be more useful.

Edit: Sorry, i didn't see you already linked to that thread.

@Hitman,

Thats ok, I already found a solution with running Dynavision with wrapper ENB version. Wierd, but solely ENB lags in certain areas, solely Dynavision has that daym invisiblity bug, but together they work perfectly for me 0_0

I`ll take a closer look on this weekend, but as a way to fix it asap - run them together. I like Dynavision for its ingame McM menu and differrent color schemes, so would like to keep them both =)

Try uninstalling and reinstalling to see if it works.
