fixed incorrect shadows which could be cast by volumetric objects in XPU depending on their transform.when using the shadowColor or presence inputs on PxrMarschnerHair) which only affected GPU rendering in XPU has been fixed. A problem with missing shadowing of semi-transparent curves (i.e.There was a bug in the lerping between MIP map levels in XPU texture() lookups when lerping between the finest and second-finest MIP map level present in a texture map.It is now possible to compile our patterns without HexTiling functionality by passing the PXR_HEXTILE_DISABLED define to oslc.Fixed a bug that could cause a crash when using OSL fmod() with differing variable types.

The bump direction now matches the corresponding old C++ bump code and the manifold version of the same code. The bump direction will change in images with OSL bump mapping and "invertT" 1 (which is the default) and the bump amount driven by a non-manifold input. The typo caused incorrect t derivative in non-manifold OSL bump mapping when "invertT" is 1 (which is the default).

Fixed typo in the argument to Dx() and Dy() in the non-manifold initTxCoords() OSL function.

PxrRamp: Added a clamp parameter to keep output between 0 and 1.

PxrPhasorNoise: Added direction flow controls to align waves along the vector direction.

PxrArithmetic now supports many more functions, mirroring Blender's Math node.

PxrSetRange: new pattern to remap signals using SeExpr's compress(), expand() and fit() functions.

New mapping applied to the roughness parameters of the lamaHairChiang node allowing for a more perceptually linear response that makes it easier the control by the user, in addition of supporting super rough fur rendering, as now roughness values can live in the full range that the Chiang model accepts.A crash when LamaLayer parameter "topMix" isn't specified has been fixed.An additional refraction roughness control has been added to PxrSurface WalterLobe.LamaDielectric: Dispersion can be specified using Abbe numbers.Clamp the topMix parameter of LamaLayer to a range to avoid artifacts.Fixed a bug where attempting to edit an invalid light could lead to a crash.due to participating media, but may lead to noticeable differences in lighting. Increasing this value can speed up scenes where direct lighting is expensive, i.e. Non-distant lights whose importance estimate falls below the specified value will be culled during direct lighting. A new Option "lighting" "minimumestimate" has been added.This option will not be available in future releases. If the old incorrect behavior is needed, please use Option "lighting" "geometryscalecorrection".

This fix may cause existing scenes with low sample counts to change direct lighting if they were converging slowly.

An issue that could cause suboptimal convergence of direct lighting from scaled geometry lights has been addressed.

The Alembic procedural will now attempt to apply velocity based motion blur for single frame archives.

Improved performance for edits to large numbers of geometric mesh lights.

Fixed a potential crash seen on extraordinary Catmull-Clark meshes with _faceindex primvar attached.

You can now override the basis for curves using the -shapeedit flag to the Alembic procedural.

Aggregate volumes bound to the interior of geometry via PxrSurface now correctly perform multiscattering through the interior aggregate, instead of reverting to the global aggregate after the first scattering event.

The msApprox controls on light sources no longer wrongly affect non-aggregate volumes in the presence of aggregate volumes.Attribute "volume" "aggregate" now supports strings that contain comma delimited names.Fixed an issue causing an offset in mipmaps generated using vdbmake.
