Hello, I had to upload a small patch today (Monday) to fix V-Ray RT GPU performance and a specific issue with VRayHairInfoTex; you will recognize it by the V-Ray RT version - 2.20.02 Note: The recent versions of the nVidia drivers will take about 4.5 GB of RAM to compile the GPU code. Make sure you have it free :slight_smile: V-Ray 2.20.01 is now available for download from our site at http://www.chaosgroup.com/ Here is the changelog since the previous release is as follows: Build 2.20.01 official (4 December 2011) ============== New features: (*) VRayHairMtl specifically for fur and hair rendering; (*) VRayOrnatrixMod modifier for direct rendering of Ornatrix hair; (*) VRayHairInfoTex texture for additional hair shading effects; (*) VRayPTex texture provides support for PTex files; (*) MaxScript functions for access to the V-Ray VFB contents; (*) V-Ray RT: added “Real zoom” option to the ActiveShade quad menu to modify the rendered region (zoom, pan) directly in the ActiveShade window; (*) MetaSL support in VRayGLSLMtl and VRayGLSLTex; Modified features: (*) V-Ray RT GPU: initial support for VRayBlendMtl materials; (*) V-Ray RT GPU: rendering of VRayProxy objects; (*) V-Ray RT GPU: support for affect diffuse/specular/reflection for VRayLights; (*) V-Ray RT GPU: support for simple skylight portals; (*) V-Ray RT GPU: support for textured area and mesh lights;

(*) V-Ray RT: support for 32-bit ActiveShade buffer; (*) V-Ray RT: add a “Reload” button for VRayHDRI that works with V-Ray RT; (*) Distributed rendering: option to specify a maximum number of render slaves; (*) Distributed rendering: when a slave completes a DR render, it will automatically try to join other running DR jobs; (*) ply2vrmesh: added support for .bgeo files in ply2vrmesh; (*) ply2vrmesh: added -info option to ply2vrmesh to print information about .vrmesh files; (*) Irradiance map format (*.vrmap) has changed - map files from V-Ray 2.20 cannot be opened by previous V-Ray versions; (*) imapviewer: added -incremental command-line option and “File > Incremental add” menu item for incremental merge of irradiance maps produced by V-Ray 2.20; (*) imapviewer: added ability to load and display light cache files; (*) VRayMtl: added “Affect channels” option for reflections; (*) VRayGLSL: split into a VRayGLSLTex texture and a VRayGLSLMtl material;

(*) VFB: added ICC color correction to the V-Ray VFB; (*) VFB: added right-click menu to the items in the V-Ray VFB history; (*) VFB: right-click menu option to add and edit comments in V-Ray History per image; (*) VFB: ability to do A/B VFB comparison with a rendered image in the V-Ray VFB; (*) VFB: the frame stamp is now saved to and loaded from the V-Ray VFB history images; (*) When writing a raw .exr file, V-Ray will attempt to produce a scanline version of the file instead of tiled one; (*) Added a glossiness render element, also for texture baking; (*) Added a Clear option for the Previous render list in the System rollout; (*) Changed the default image sampler to Adaptive DMC; (*) Exposed the irradiance map preview mode parameter in the UI; (*) Reduced flickering of the irradiance map and light cache when “Time independent” DMC option is disabled; (*) Disable any HSDS modifiers before saving the scene for DR; (*) SDK: switched to Intel C++ 12.1 compiler;

(*) Nitrous: the first time the user selects “Show realistic material in viewports” the objects with this material disappear; (*) The material texture maps were not shown in the Max2012 shaded viewport; (*) DR: fixed hanging buckets in specific cases; (*) DR: slaves with missing files continuously tried to re-join a DR render when “restart slaves on render end” was on and “Check for missing files” was enabled; (*) DR: if a render slave failed to receive the entire irradiance map from the client it still continued the render producing wrong buckets; (*) VRayBPTracer: region rendering did not work; (*) VRayFastSSS2 did not work correctly with light exclusion; (*) Assigning a texmap to material texmapslot caused a crash when the texmap was disabled; (*) Exclude from shadow casting did not work for VRayIES lights; (*) Fixed a crash when rendering with Particle Flow emitted from animated geometry; (*) Fixed a crash with VRaySun when the scene is rendered with the scanline renderer; (*) Fixed uneven motion blur for fast moving objects with many geometry samples; (*) Scrubbing the time slider created keys for the FOV parameter;

(*) AA filter type not saved in V-Ray presets; (*) Loading a V-Ray preset does not respect the selected rollouts; (*) Scripted materials are not handled properly when assigned as sub-materials; (*) V-Ray RT: environment override slot in VRayMtl did not work with glossy materials; (*) V-Ray RT: DOF did not work with animated cameras; (*) V-Ray RT: gamma issues with the ActiveShade window; (*) V-Ray RT: IFL sequences did not work with VRayHDRI; (*) V-Ray RT: initialization error in stage 2 when Mix material is used as normal map; (*) V-Ray RT: differences in RT with 3dsmax Composite map; (*) V-Ray RT: environment override slot in VRayMtl materials doesn’t work for glossy materials; (*) V-Rat RT GPU: OpenCL code failed to compile with the latest nVidia drivers;

[image]On another topic Actually, does it even support Max’s Hair and Fur? It doesn’t seem to work here… Or is it just for Ornatrix? Works for me… Best regards, Vlado

doesnt work for me. the hair material is being ignored. is there any thing one is supposed to do? should we use geometry, buffer or MRPrim?

Looks like everyone is Vray’ing this Saturday :slight_smile:

I wonder about the Environment Variable we created for rendering with the old DMC Sampler of Vray 1.5 to be able to get noise-free and RAM-free renders. Should we still keep that or is the DMC Sampler in the update working fine?

hmm is this something i missed? which environment variable?

[image]Old files I wonder about the Environment Variable we created for rendering with the old DMC Sampler of Vray 1.5 to be able to get noise-free and RAM-free renders. Should we still keep that or is the DMC Sampler in the update working fine? Please see my reply in the other thread. V-Ray 2.20 produced the same noise levels as V-Ray 1.5 SP6 in all of the tests that I did. However it may still be useful to do a few tests of your own. Best regards, Vlado

Oh well. If anybody got any clue as to how to apply the new hair shader to a standard Max Hair and Fur modifier, it would be very welcome.

Will get you a scene in a moment… Best regards, Vlado

@BBB3: Yes, a tip how it works with standart hair & fur would be great. @ chaos group: i’ve not much posts but i’m with you a long time. You guys doing a great job but i cannot understand why you don’t make any manual of your product or your nice upgrades. For 2.0 it was just a modification from the (i don’t know) 5 years old 1.5 version. I know there are a lot of tutorials but a documentation where all the parameters are explained is much better.

Here is an example scene; not very good, but I hope it is enough for a start: Chaos: Industry-leading design and visualization software Best regards, Vlado
