This is a bugfix release, fixing Houdini Indie on Windows and Mac, and adding SDF volume rendering.
This release uses Arnold 188.8.131.52 and OpenVDB 3.1.0.
Binaries available for the following Houdini, Houdini FX, Houdini Indie and Houdini Education production builds:
and for the following platforms:
- Linux x86_64 (gcc4.8)
- Windows 7 x64 (vc11, vc14)
- Mac OS X 10.8+ (clang7.3)
Please note that Houdini Apprentice does not support third party renderers and thus cannot run HtoA.
- SDF volumes: The
volume_sample_floatshader now supports Signed Distance Function grids, allowing precise volumic representation of polygonal objects with less voxels (htoa#801). This adds 4 new parameters to the
volume_type: Interpret the volume data as fog (density) or SDF (signed distance function). In SDF mode, the inside is converted to a constant density of 1.
sdf_offset: Offset the SDF values by this distance, allowing to dilate or erode the SDF boundary shape.
sdf_blend: The distance over which to smooth out the edges of the SDF.
sdf_invert: By default, positive distances represent space outside of the boundary while negative distances mean inside. This parameter lets you invert this convention.
- Orthographic adaptive subdivision: Adaptive subdivision mode now works with orthographic cameras (core#5425)
Fixed incorrect texel offset from
persp_camera.uv_remap.This will slightly change the output of cameras using a distortion map (core#5420)
- Fixed Houdini Indie rendering on Windows and OSX (htoa#808)
- Fixed "invalid parameter name" log messages (htoa#799)
- Fixed crash when calling
asCode()on objects with Arnold properties (htoa#809)
- Fixed incorrect motion blur with timeblend SOP (htoa#811)
