Shader error ?
MootoolsSoftware opened this issue · comments
Model: Netsuke_-_Shoki_capturing_an_oni.zip
Source: Sketchfab
Reproduce code:
tydra_to_renderscene.exe "Netsuke_-_Shoki_capturing_an_oni.usdz"
Parsing the following model return an error on windows:
Is this a problem in the shader or the model?
We can't decode the error and are not able to know if this is a lib limitation or conversion problem.
As the message says, outputs:rgb is supported but outputs:r is not yet supported in TinyUSDZ Tydra API
https://openusd.org/release/spec_usdpreviewsurface.html#texture-reader
This will be implemented along with USD to RenderMesh conversion task #109
Supported outputs:r(and others) in recent dev branch.
And now tydra::DumpRenderScene prints outputChannel parameter
