  • V-Ray 2.0 for Maya Beta 2

    Hello,

    We have uploaded beta 2 to our web site. Here is the changelog from Beta 1:

    V-Ray 2.0 for Maya, Beta 2
    =========================

    Modified features:
    (*) Support for Maya 2012;
    (*) Initial support for V-Ray materials in Viewport 2.0 in Maya 2012 (may be somewhat unstable on Mac OS X);
    (*) Added "Compensate camera exposure" option for VRayToon;
    (*) The "Inclusive set" option for VRayToon is now off by default;
    (*) Floating-point colors are written to the Render View for Maya 2011 and later;
    (*) Added a "RT Image Ready MEL" callback that is executed when the RT engine completes a frame;
    (*) The installation now adds an environment variable VRAY_TOOLS_MAYA* to specify the location of the additional V-Ray tools;
    (*) The PTex loader prints messages to the log whether the PTex file was successfully loaded or not;
    (*) Additional color space attributes for PTex textures;
    (*) Added new "absolute" mode for vector displacement that matches the floating-point vector displacement maps from Autodesk Mudbox in "Absolute tangent" space;

    Bug fixes:
    (*) Incorrect texture filtering with specific meshes;
    (*) Crash with img2tiledexr if a wildcard pattern does not contain a path;
    (*) Crash with VRayToon when hiding all elements in the scene;
    (*) Some V-Ray AE templates were not loaded on Linux;
    (*) Connecting attribute to attribute when the destination is VRayMtl didn't work in Hypershade;
    (*) VRayPTex didn't work as a bump map;
    (*) VRayFastSSS2 could produce invalid colors with the raytraced single scatter modes;
    (*) Various documentation errors in the V-Ray SDK;
    (*) Fixed help links for VRayFur and VRayFurSampler nodes;
    (*) Fixed help links for VRayEnvironmentFog, VRaySimpleFog, VRayScatterFog and VRayMeshMaterial nodes;
    (*) V-Ray RT: Fixed issues with shading groups update;
    (*) V-Ray RT: Fixed crashes with VRayFur and other dynamic geometry when the dynamic memory limit is low;
    (*) V-Ray RT: Changes to VRayFur were not updated in the RT engine;
    (*) V-Ray RT: 2D displacement did not work properly;
    (*) V-Ray RT: VRayPTex textures could disappear when adjusting a VRayMtl material;
    (*) V-Ray RT: Attempting to render a particle instancer produced a fatal error while translating the scene;
    (*) V-Ray RT: Crash when attempting to render large resolutions;

      Good question There is a bug in the UI which is fixed for Beta 3, but in the meantime, use the following MEL command:
      Code:
      setAttr "vraySettings.aoOn" 1;
      There is also another bug where if the AO amount is less than 1.0 it is assumed to be 0 and has no effect - this is also fixed for Beta 3.

            Zdravko, thank you. I was hoping to find some instruction for the RT Engine. I actually had found that page before, but it doesn't seem to cover the new RT Engine tab. I was at the LA demo at RFX and am very excited to get started. I was at the back of the room so I could not see how to start using the RT, any help would be much appreciated.
            Cheers!

              Hi Brad, it's pretty straightforward. It seems like you've installed the Vray for Maya 2.0 Beta, so you're halfway there. Just start Maya, and select Vray as the renderer.

              IMO, I would start with Vray RT in CPU mode first. So goto your render settings, click on the RT Engine tab, and make sure the Mode is set to CPU. Next, just add a cube to the default scene and click the IPR button on your shelf, and that should start Vray RT. You'll see a progressive render in your Maya frame buffer and Vray will launch a new console window where the Vray RT output messages are displayed.

              As far as Vray RT GPU - I believe you have to have a CUDA enabled graphics card, and be sure to download the latest drivers for you graphics card. Stop the IPR [if its running] and close the window. Then it's just as simple as opening up your render settings, RT Engine tab and switching the mode to GPU. The very first time you run Vray RT in GPU mode it can take upto several minutes for the OpenCL code to compile in some cases.

              Best wishes.

                Quick question: are the glare and bloom lens effects in the Maya beta?

                edit: never mind, found the answer

                    Hi bradjhayes,

                    In order for the RT to work vray standalone ( /Applications/Autodesk/maya2012/Maya.app/Contents/vray/bin/vray )
                    needs to open a port (20207) for listening.

                    It seems, it failed on your machine.

                    Can you check if you have:
                    1. something else running on port 20207
                    2. a firewall preventing vray to open the port

                    To check if something has opened the port.
                    To do so use this command (you have to open a terminal): "lsof -i -P | grep 20207"

                        Does vray standalone start, when it is started from the terminal manually?
                        To start it use this command: /Applications/Autodesk/maya2012/Maya.app/Contents/vray/bin/vray -server -portNumber=20207

                            This error code means that the address is already in use, so something has opened the same port.
                            Can you try to use -portNumber=20206 for example, to see if the server will start?

                            Also try the "netstat -an | grep 202" command and paste the output in the forum.

                              Ok, first the good news I tried running the -portNumber=20206 and that did seem to start the standalone. see the following:

                              I was hoping that with the standalone running it would just work, but when I went to the IPR nothing seemed to happen. When I ran the second command you gave me I got the following:

                              I really appreciate the help. I at least feel like I'm getting closer. So what would you suggest next.
