Replacement issues in Shader-heavy games

[Kim2091]

This entire thread relates to these 3 games:

• Barnyard
• Skyrim
• Fallout: New Vegas

First Issue When adding lights to meshes (following the proper steps), the lights "float" and are attached to the player camera or mesh instead. The lights then follow the player/camera until it's culled from being out of range. Examples:

Second issue In Skyrim specifically, captured meshes are actually stacked on top of each other, losing their original positions. This occurs with multiple objects, although there's no consistency to which ones it occurs with. The main object types this happens with are light sources though (torches, chandeliers, etc.). Examples here:

New 3rd Issue Mesh replacements do not work properly. They behave similarly to light additions, where they're attached either to the player, or the player camera. See this comment: https://github.com/NVIDIAGameWorks/rtx-remix/issues/181#issuecomment-1613669477

• Remix build: d8bf66a (and many earlier ones)

• Fallout NV: Steam

Attach logs! Logs produce nothing helpful here

To Reproduce Steps to reproduce the behavior:

First Issue

1. Add a light to a mesh as you normally would (https://discord.com/channels/1028444667789967381/1096847508002590760/1096847729788977183)
2. Load in-game
3. Observe the issue

Second Issue

1. Load Skyrim with this conf file: https://cdn.discordapp.com/attachments/1097563444137427056/1113888845298143322/rtx.conf
2. Make a capture of the Sleeping Giant Inn
3. Look at the captured torches on the wall

Third Issue

1. Replace a mesh per Mark's newest tutorial in one of the specified games: https://discord.com/channels/1028444667789967381/1096847508002590760/1123306156773879928
2. Observe end result. The mesh should be anchored either to the player position, or the player camera

Expected behavior

1. The light should remain attached to the mesh. This is not the case, as it follows the player mesh or camera.
2. Meshes should not be stacked, and should appear in their original positions
3. Meshes should remain in their designated locations

Note: Updated with the mesh issue

This is exhibited in Fallout New Vegas

New behavior. I also replaced meshes for the first time this week. Here's the result in Barnyard:

https://github.com/NVIDIAGameWorks/rtx-remix/assets/62084776/ce5e6245-646d-47e1-9452-efb851146982

In this instance, I replaced the table meshes in the scene with the character model, just as a test. As you can see, a solid black mesh is attached to the player model, rather than being in place of the tables.

I used the same process of mesh replacement in Morrowind, per Mark's suggestion to attempt it in another game to verify I'm doing it properly. It does indeed work: https://cdn.discordapp.com/attachments/1097049994156060682/1123494675827929149/image.png

I just wanted to update and say that this is sadly still an issue. I tested a mesh replacement again in Barnyard, and it seemingly has improved a small amount, but not much.

Rather than being stuck to the player's position, it now just follows around the player similar to light behavior:

There's a new game experiencing this issue: Kingpin: Life of Crime

I can also confirm the same issue in Prince of Persia: The Two Thrones

[NV-LL]

Hello! Will you please test this on the 0.5 release and let us know if the issue persists? Thank you!

[Kim2091]

@NV-LL I can confirm that the issue unfortunately persists in Barnyard (and almost certainly the other games as well). Here's a new video and example

In this example I have anchored a cube to this vase mesh.

This is how it looks in-game:

https://github.com/NVIDIAGameWorks/rtx-remix/assets/62084776/e5499c42-9d27-4581-a621-26c328ecea18

As you can see, it tracks the player camera instead of staying anchored in place. It is also culled as soon as the vase is culled, which proves it's anchored to the correct mesh.

One more thing that I've seen since the original post: scene scale does not actually work other than for terrain baking.
