[REQUEST] Investigate into fixed-function rendering DX9 support for RTX Remix compatibility.

[Russell-Beach]

Marble Blast Ultra, being built on a DirectX 9 version of the Torque Shader Engine, does not currently have RTX Remix compatibility due to using shaders. Currently there does exist some console commands that can make the game enter a fixed-function fallback mode, but it is not sufficient for RTX-Remix compatibility as of this time.

$pref::Video::forcePixVersion = true;
$pref::Video::forcedPixVersion = 0;

In the current state, RTX remix is capable of hooking into MBU, but is unable to begin ray tracing. RTX remix is able to find the games graphical assets, but cannot export those graphics to a USD scene for use in remixing and asset replacement.

Although not currently critical, getting RTX-Remix fully functional would be very interesting to allow the game to have a higher level of graphical fidelity that can better leverage the advances in hardware since the original 2006 release of MBU.
