2026 Kit CAE in RTDT Blueprint

[FlowTwinAI]

how is the volume data (index-Xform) called in the blueprint . Most CAE prims are in non edit state ? any clue

Not sure I follow. There's nothing different about the stage in RTDT. The webapp may make it challenging due to mismatch in the browser and kit aspect ratio (something that'll get fixed in the next release). You can always directly launch the editor app and update the stage as needed.

Hello Utkarsh, Some prims related to CAE (streamlines, VDB)are disabled. Have you run this in any case ? I can see inferencing for design changes but the results don’t display !

How did you manage the Aeroplane demo via web app ( was it KIT CAE2.0, latest RTDT) ?

Seems the blueprint (Index-Xform) is looking for volume assets (VDB) that are either pre-configured to a local path (or) specific layers are handling it. Needs to be confirmed !

[utkarshayachit]

the airplane demo was largely done as a refactor of the RTDT with considerable changes to the stage. We're working on updated version of RTDT that's based on Kit-CAE 2.*.

That's not correct. The Volume prim is setup with attributes for IndeX that makes it read data coming in from the Inference via the corresponding CaeDataSet.

Somthing isnt trivial in RTDT .. that is not allowing the CAE data to be previewed by default.

The vdb path the code is looking for : Asset(../E:/Projects/Datasets/modulus/driveSim_0_conv.vdb) data read failed with Response 6
which doesnt exist

Even usdpaths refer to the hardcoded local path

I am not too familiar with the old stages. An entirely new implementation + stage is getting prepped for release in mid-May.

Sure Thanks. would be glad to try out any Beta setups if they can be shared before release.

the old stages.

• seems like a Rabbit hole ..

the /RTWT_IndeX.usda has these hardwired.
