Correction:   MentalRay in SI may not be using that, but Arnold, Redshift, and 3Delight in SI do   (among many other updates) Including things like VDB support etc... (None of which would have happened had there not been any usage/demand (more than a year post EOL) Recent changes (2015) for Arnold & 3Delight for Softimage, (Redshift updates would just be too long to list) Arnold for Softimage 3.8 July 13, 2015 Faster export times overall on Windows (up to 20% faster). Faster export of polygon meshes (up to 35% faster). Much faster export of ICE instances (up to 5x faster) and ICE primitive cylinders, discs, cones, boxes (up to 3x faster). Faster rendering when using SItoA shaders on Windows (up to 15% faster). 3.7 June 10 2015 Faster cutout texture mapped opacity, with more accurate renders (in previous versions, an object was rendered more transparent when it was further away from the camera). Multiple scattering for volumes: Indirect light in volumes now supports an arbitrary number of bounces instead of being fixed to one bounce. Per-light volume contribution: A volume contribution scaling parameter was added to lights, similar to the existing diffuse and specular parameters. Deep volume output support: Volumes are now visible in deep renders (note that older atmosphere shaders and volumetric mattes are not supported yet). The volume property now shows the names of available grids in VDB files. Faster UDIMs: UDIMs accessed through the built-in image shader node now internally use texture handles, which helps improve multi-threading performance. 3.6  April 27 2015 Optimized volume rendering Fixed long-standing artifacts with large ray marching steps Faster volume caches (such as OpenVDB) in IPR 3.5 March 09 2015 Transmission component in the hair shader. Support for the Volume primitive as a property and volume_sample shaders added. Mattes now work with volumes as well. 3.4 January 16 2015 Faster Curves and Volumes. Opacity controls added to the Skin Shader. The autobump detail enhancement now works for procedurally displaced polymeshes even when there are no UV texture coordinates. 3Delight for Softimage  Changelog 4.0.49 - 2015-07-24 OpenVDB. Fixed output to Preview window when all the Render Channels are disabled. All the lights are hidden and the raytracing is disabled when Main Render Channel is not enabled. Display first enabled Render Channel in the Preview window (it was unconditional displaying of Main Render Pass). 4.0.48 - 2015-07-23 Added 3Delight Hair material. More detailed profiling. 4.0.45 - 2015-06-04 Fixed light visibility in IPR Default SSS Algorithm is Ray-tracing No limit for GI and SSS samples 4.0.43 - 2015-03-12 Output rendering progress to stdout Fixed mesh lighting in RIB export Fixed float precision in fog 4.0.41 - 2015-02-21 Faster reflections when using multiple bounces. 4.0.40 - 2015-02-13 Ignore the Smooth Subdivision Threshold if the object has displacement Don't skip environment map rendering if there are no envmap files Fixed bug when a light can't be changed after user changes Interactive Rendering Type Support for JSON statistics ESC key stops the rendering 4.0.38 - 2015-01-06 Fixed depth in deep output with path tracer. Also an SI|3Delight feature list, showing how tight integration is, (arguably 'tighter' than Arnorld and Redshift which are already considered extremely well intergrated) As a cost-effective solution (notwithstanding the first free license) and since pathtracing was introduced, as an easy/worry-free (Arnold-like) solution (only slightly slower than Arnold for similar noise levels) also not only supporting, but excelling at 'specialty' things like hair/fur, rendering *tons* of particles, and things you never thought would have worked, let alone work well, (also mentionning EXR 2.0 at the end) Cheers! Integration with Softimage   Great care has been taken to ensure a seamless integration with Softimage: Complete Render Tree support 3Delight for Softimage fully supports Softimage’s render trees (including compounds) and all materials. ICE Support  Point Clouds and ICE attributes are fully supported and efficiently rendered. Stand-Ins 3Delight for Softimage fully supports stand-ins for efficient rendering of large data sets. Softimage Properties Compatibility 3Delight for Softimage recognizes all the common rendering properties so that its behavior is as close as possible to Softimage’s internal renderer. Rich Geometry Support Support of all Softimage geometry with the added benefit of perfectly smooth rendering of Subdivisions and NURBS (no tessellation or polygonal edges at any detail level). Toon rendering and Inking  All toon shaders are supported and the ink lens shader is also supported. 3Delight for Softimage is able to render beautifully anti-aliased outlines, fast. Hair Hair is rendered using 3Delight’s efficient curve primitive. Linear, quadratic and cubic curves are all supported. Hair instancing is fully supported as well. Polygons All types of polygons are supported. Also, polygonal geometry with a subdivision step greater than 1 will be rendered as a smooth subdivision surface. Edges and vertices tagged as “hard” are rendered properly. Point Clouds All particle shapes are supported with proper shading. 3Delight for Softimage can take advantage of 3Delight’s lightweight particles to render extremely large clouds of point-shaped particles. NURBS All NURBS surfaces are supported. Trim curves on surfaces are also fully supported and rendered to sub-pixel accuracy. Curves 3Delight for Softimage can render Softimage curves of any shape and degree. Curves are smoothed to sub-pixel accuracy.   Main Features of 3Delight for Softimage Powerful Rendering Engine Supporting both path-tracing and REYES algorithms. Path-tracing allows for real time modifications of the camera, the lights and the materials. Fast Indirect Illumination and HDRI A novel two-pass algorithm allows for efficient rendering multi-bounce indirect illumination. Environment sampling (HDRI) works well even with the very high dynamic range data without the need to blur the environment maps. Motion Blur and Depth of Field Multi-Segment motion blur and realistic camera shutter simulation contribute to high quality rendered images. Compared to other rendering software, motion blur in 3Delight for Softimage is fast. Depth of field is fully supported and simulates a realistic camera bokeh. High Quality Anti-Aliasing Edge anti-aliasing, motion blur and depth of field quality are all controlled using very simple and predictable options. Contrary to other rendering software, increasing pixel samples for higher quality anti-aliasing does not affect performance significantly. Geometric Displacements Displacements are efficiently rendered to sub-pixel accuracy.   Subsurface Scattering Automatic subsurface scattering can be enabled on a per-object basis and delivers impressive results, fast. All standard Softimage materials can be used without modification to achieve subsurface scattering effects. High Quality Fur Rendering Deep Shadow Map technology provides production grade quality and performance. Multi-Channel EXR and Deep Output Ability to output "deep data" as OpenEXR 2.0 files. Compatible with Nuke. On 08/27/15 8:44, Jens Lindgren wrote: Not many people use multilayer exr because it's slower to read than splitting it out to different files. This slowness is solved with EXR 2.0 but Softimage isn't using that. Don't really know if it's possible with MR but in Arnold you simply name the framebuffers the same and it gets merged to one file. Maybe that's how it works in MR as well. /Jens On Wed, Aug 26, 2015 at 9:35 PM, Pierre Schiller <activemotionpictu...@gmail.com> wrote: bump On Mon, Aug 17, 2015 at 7:28 PM, Pierre Schiller <activemotionpictu...@gmail.com> wrote: bump.

I know this has been posted a lot of times, but I was wondering if AD did ever fixed the issue with multilayered .exr images on a single file from MR? (mental ray). I know all other render motors work normally when rendering layered .exr images (arnold, vray, etc..) But SI 2015 can already render .exr layered image (zdepth,normals, etc.) on a single file? Store in channels work well... I guess, but I was asking this if there´s any possibility to work those layered passes directly from the render manager? Thanks.
