What's New
RIS and XPU
Add new "live stats enabled" pref for DCCs
RIS
XPU
xpu renders from DCC's can now cancelled from "it" (hotkey escape or stop toolbutton). Select object and select shader tools now also function in "it".
Other
Changes in Stylized Looks
PxrStylizedHatching:
- New "Blend White Lightest" feature to give control if brightest value is solid color instead of highest hatching texture
- Hatching specular invert texture progression support for triplanar projections
- Fixed overbrights mapping: eliminates artifact in Screen & Triplanar projections
- New "Signal Energy From" option: "Signal AOV Mono" for whiteshader calculations
PxrStylizedControl:
- New Feature: "Sections Add" for additional random modification for edge detection in PxrStylizedLines
- New Feature: "Sections Quantize" for additional random modification for edge detection in PxrStylizedLines
- Updated "Sections Spread Scale" functionality for more space between random colors for edge detection in PxrStylizedLines
- Fixed bug where AOV's previously overwritten if also written in other Pattern node (like PxrTee)
Other Bug Fixes

"it"
hdPrman - the RenderMan Hydra Renderer Delegate
Fixed a bug where file textures from material x networks would appear vertically flipped in RenderMan renders. The old behavior can be restored via the env var HD_PRMAN_MATERIALX_VERTICAL_FLIP=false
- Bail if we see a "multioutput" connection, since these aren't supported yet (Note, studio has added support, but involves a USD change that we're not using yet)
Fixed an issue for mtlx image files where the rtx plug-in gets referenced. The heuristic for grabbing the texture node ptr was sometimes failing.
Fixed an issue for tex files: resolve the path, because RenderMan doesn't know about usd file relative paths.
For mtlx image file nodes without a texcoord connection automatically wire in a mtlx geompropvalue specifying st texture coords
