Hi,
we are in the process of updating USD from 23.02 to 23.11 and noticed a change in the returned paths.
we have a simple test USD that points to a texture using <udim>
tag in the path
#usda 1.0
(
upAxis = "Y"
)
def Scope "mtl"
{
def Material "material"
{
token outputs:surface.connect = </mtl/material/PBRShader.outputs:surface>
def Shader "PBRShader"
{
uniform token info:id = "arnold:standard_surface"
color3f inputs:base_color.connect = </mtl/material/diffuseTexture.outputs:rgb>
token outputs:surface
}
def Shader "diffuseTexture"
{
uniform token info:id = "arnold:image"
asset inputs:filename = @C:/CODE/pyCharm/pipeline/fin_unittest/TEST_PROJECT_0/_Temp/Creatures/gorilla-tex/lookDev/texture/texture/0001/gorilla-tex_lookDev_texture_v0001_base_colour.<UDIM>.exr@
color3f outputs:rgb
}
}
}
when we query the dependencies of this file using UsdUtils.ExtractExternalReferences
we get the exact same path as in the USD file from 23.02
. However, 23.11
returns it as: gorilla-tex_lookDev_texture_v0001_base_colour.1001.exr'
23.02
β gorilla-tex_lookDev_texture_v0001_base_colour.<UDIM>.exr
23.11
β gorilla-tex_lookDev_texture_v0001_base_colour.1001.exr
this may have unforeseen implications in our pipeline and I wanted to check if this is the desired outcome and what the thinking behind it is. From the current API we donβt know if this is a single texture or a sequence (maybe the artist wants to have the same texture on all udims etc?)
