Solid Angle Houdini to Arnold 5.4.0 | 775.3 mb

The Arnoldrenderer product team is pleased to announce the availability of Arnold (or HtoA) 5.4.0 for Houdini. This release brings improved Solaris support including support for rendering curves, and fixes issues with alembic packed primitive translation.

This is a minor feature release, using Arnold 6.0.4.0 and Arnold-USD (6b712999). It is fully binary compatible with 4.0.* versions.

Enhancements

    htoa#1419 Support spotlight shaping parameters in Solaris
    htoa#1422 Support mat context in Force Materials and Assign Material
    htoa#1425 Add Arnold parameters for Render Vars LOP
    htoa#1427 Add GPU settings to render settings LOP
    htoa#1445 Add rim_light_tint to toon shader
    htoa#1447 Update RenderVar parameter naming conventions
    htoa#1453 Refactor Solaris LOP UI code
    htoa#1459 Get GPU device list for Solaris render settings LOP
    htoa#1472 Dynamic creation of render geometry settings
    htoa#1481 Add preset for AA_inv_density to AOV list
    htoa#1514 Create curve parameters for the render geometry settings LOP
    htoa#1515 Increased default texture maximum memory

- Automatic file path remapping: String parameter values can now be automatically modified according to the OS Arnold is running on. For example, this is useful when the artist workstations are running Windows but the renderfarm nodes are running Linux. Configuration is done with a JSON file that contains the strings to search and replace for each OS. This configuration file can be selected through the ARNOLD_PATHMAP environment variable.  (#9311)  For example:
                 

               
Rim light control for the Toon shader: A new rim_light_tint float parameter was added to the toon shader to tint the color of the rim light using the base color of the surface. See the full documentation. (#9003)

Performance improvements on Windows with many cores and texture-heavy scenes: Several performance improvements have been made, particularly for those running Windows, using many cores, tiff based textures, and/or reading many textures/sec. Expected speedups can be anywhere from a few percent to orders of magnitude faster on many-core Windows machines. (#9515, #9685, #9686, #9695, #9709, #9761) For a medium complexity scene that uses exr based .tx textures we get the following speedups on Windows :

- String parameter path metadata:  A new path metadata can be assigned to string parameters to give specific hints about how they will be handled. Currently available values are: file, folder and folderlist. Arnold will expand environment variables, apply the remapping, and handle backslashes on string parameters with the metadata. (#4969)
- AA_adaptive_threshold in log: The options.AA_adaptive_threshold used is now output in the log file. (#9841)
- Upgraded OSL:  Arnold now uses OSL 1.11.6 bringing multiple optimizations and bug fixes, see the full list of changes. (#8917)

GPU Enhancements

- Global AOV shaders: The aov_shader option is now supported on GPU. This option defines a list of shaders that the renderer will evaluate after the regular surface shader. With this, it's possible to add shaders to set specific AOVs without modifying the original shader tree. See the option documentation. (#9394)
- Initial support for attributes in OSL:   You can now retrieve user data bound to shapes via the getattribute function or via a lockgeom parameter attribute. This initial implementation still has some limitations when compared to the CPU implementation. Queryable attributes are currently restricted to those bound to the current shaded shape and attributes of the active render camera. Querying node parameters is also not yet supported. (#9666)
- Initial support for tracing in OSL:   You can now use the trace function to trace rays in OSL shaders along with the getmessage function to retrieve information regarding any intersected object. This initial implementation has the restriction that you cannot yet query parameters on an intersected object. (#9797)

USD Enhancements

- UsdRender schema: UsdRenderSetting, UsdRenderProduct and UsdRenderVar are now supported in the procedural. (usd#453)
- Improved Solaris Primvar support: Primvars with arrays of a single element are converted to non-array user data in Arnold. This improves primvar support in Houdini Solaris. (usd#456, usd#463, usd#478)
- Curve support in the render delegate: Curves now render in the Arnold render delegate (usd#483)

Incompatible Changes

- AiMsg* changes:  Changes have been made to how logging behaves. Now the log session is for the life of the Arnold process instead of just between AiBegin/AiEnd pairs. If messages are not showing up or too many messages show up, you might need to set the logging flags and other options before calling AiBegin. Another change is that you can now set the log filename at any point in time, each time AiMsgSetLogFileName is called the previous file will be closed and the new file will be created. See the API documentation for the full set of functions. (#9575)
- Increased default texture maximum memory:  The options.texture_max_memory_MB default value has been raised from 2048MB to 4096MB. (#9846)

Arnold for Houdini (HtoA)     provides a bridge to the Arnold renderer from within the standard Houdini interface. Having been in beta for several months, the plugin has already been used in production by many studios, including Prime Focus World for Hercules and Vampire Academy, Milk VFX for the Sherlock and Doctor Who TV series, and Framestore NY for the Captain Morgan commercials.
 
Solid Angle SL     is the technology company behind the Arnold rendering software, with offices in Madrid and London and customers throughout the world including Framestore, DreamWorks, ILM, Sony Pictures Imageworks, MPC, The Mill, Mikros Image and Rising Sun Pictures. Arnold was designed from the ground up to efficiently raytrace the complex geometric datasets required for feature­-length CGI animation and big­ budget visual effects, while at the same time simplifying the pipeline, reducing the number of passes, minimizing storage requirements and greatly enhancing interactivity for lighting artists.
