How do I make Darth Nihilus become transparent and gradually fade away as he disintegrates in the game?

Hello.  So a while back, I made a post called "Dumb question, but what graphics are required for a smooth dissaperance in a cutscene?".  The post basically was about the way Darth Nihilus fades away as he dissolves into a red "cloud" of dark side energy.  Back then, I didn't have the game yet, and now I do.  

There are some playtrhough videos on YouTube of KOTOR II, both TSLRCM and TSL vanilla, that have Darth Nihilus fade away gradually and become transparent before completely vanishing in the red cloud. The way he vanishes into the scarlet red dark side "smoke" looks super clean and transitions nicely, his model fades and becomes more transparent as he fades away in the cloud.  However, there are other playthroughs of the game, both vanilla and TSLRCM, in which he doesn't vanish the same way as others.  Instead, he just glitches out of existence after the dark side energies combust out of him without fading gradually and becoming more transparent.  His model just stays the same before he just pops out of existence in the cloud.

I really like the effect where his model becomes transparent and fades away in the cloud, as it looks more realistic and looks like a visually stunning effect, but in my own personal playthrough of the game, my fear was true.  He just glitches out of existence, the one where he doesn't become transparent.  I made a video of what I want the death of Nihilus to look like vs what I have in my actual game.

I want to make him become transparent and fade out gradually, but I don't know if it is graphic or resolution issues or a script thing.  To give you more context, here is what I have on my game.

I have the GOG version of the game, (Good Old Games), specifically the GOG Galaxy version of the game. I am running this on a Nimo Gaming laptop.  I had installed TSLRCM to my computer, then I installed the Unofficial TSLRCM Tweak Pack, specifically the tweak that removes the Visas Marr and Mandalore conversation on the Ravager and makes the cutscenes run like in the vanilla game.  The footage you see is from my game with those mods installed.  I then began to wonder if this was a product of the Tweak Pack and/or TSLRCM, so I uninstalled those mods and played the save game of that level vanilla, but same result, (to be fair though, I was playing from the same save after I uninstalled the mods, so I dunno). 

This is all REALLY weird because I myself am making a mod where I use the sithritual001 effect on Darth Sion in the final battle level with him on Malachor V, and he has the transparent gradual fadeout but somehow Nihilus doesn't.  You can see a snippet of my "earlier revision" of the Darth Sion mod here, where he is seen fading out and becoming transparent. 

I want to find the root of this problem, mind if anyone helps me please? Help would be greatly appreciated.

Okay, I learned some new information.  First of all, it seems like both TSLRCM and vanilla TSL in KOTOR II have the fadeout transparent effect.  I have seen some playthroughs  for both versions on YouTube where the transparent fadeout happens.  It seems like all of the YouTube playthroughs that DO have the transparent fadeout effect are Xbox or older PC.  It seems like PC playtrhough videos from 7 years ago to now seem to have what I have: The solid "DestroyObject" effect. I set the script to both "TRUE" or "FALSE", and even used the "DelayCommand" for DestroyObject, and no fadeout.  I then came to the conclusion that it was a video card rendering and/or graphics issue.  I tried changing the graphics in a variety of ways, both in-game and in AMD settings, but it doesn't do anything rather than change the "sithritual001" cloud effect's texture. I shared the savegame with a modder on the OpenKOTOR Discord, and it seem like in their playthrough of that save, which is Steam version, specifically Steam Proton Linux, there is no fadeout either.  Regardless of what graphics or anything that I do, whether it is edited or default, the fadeout doesn't happen, but it works for Darth Sion and even Darth Traya. Is there something "broken" about PCs to render this properly, or is it perhaps not a graphics thing either and is another issue entirely?
