VRay RealTime

NOTE: This product requires that you already own 3ds max and VRay 1.5 SP3 or above.

VRay RT is NOT compatible with VRay EDU.

*** Available for US, Mexico and Canada only. Other Nations must purchase from their local dealers, per request of Chaos Group (makers of VRay).

** All licenses are non-transferable once registered. Once having purchased the product, the end user will not be allowed to transfer or sell their rights to third parties.

Free Domestic ground shipping (if shipping is necessary - see below)

LICENSING: the VRay RT license resides on a WIBU key. You can add it to your existing VRay Advanced WIBU key. Because VRay RT requires VRay Advanced for 3ds max, most customers will prefer to reprogram their hardware key with the added license. If you never got your WIBU hardware key but you do own any prior version of VRay Advanced for 3ds max, contact us and we will provide you with a key.

INSTALLATION: You will be able to download the VRay RT installer for your version of 3ds max from your account at ChaosGroup.com . If you have lost your login information, please contact us and we will resend it.

Product details:

Created with the busy and rigorous 3D artist in mind, this top notch raytracing technology allows immediate interaction between the user and the virtual environment. V-Ray RT follows the user’s actions while working on the scene and automatically and progressively generates a photorealistic preview of the scene. Designed to improve and speed up the Texturing and Lighting stage of 3D scene creation.

General
The V-Ray RT interactive rendering system has many advanced features; here only some of them are listed. Note that all features are subject to change without special notice.

Currently it is CPU-based. Does NOT require special graphics cards
Currently the V-Ray RT technology is based on CPUs - it does NOT require any special or expensive graphics cards. All V-Ray RT needs is CPUs. As usual - we will use ALL of your CPUs and cores at no extra license cost.
However, the V-Ray RT architecture is very robust and if needed - it can seemlessly be implemented to allow new hardware acceleration technologies in the future.

Distributed rendering
V-Ray RT supports distributed rendering across multiple machines in the local network.

Integration with 3ds Max
V-Ray RT is an ActiveShade renderer in 3ds Max, separate from the production V-Ray renderer. V-Ray RT does not introduce new plugins other than the interactive renderer itself. Instead, the existing 3ds Max and V-Ray materials, textures, lights, cameras etc. are used.

V-Ray RT consists of two major components:

• V-Ray RT interactive renderer in 3ds Max;
• One or more V-Ray RT render servers.
  

Interactivity
A major feature of V-Ray RT is its ability to track changes to the scene performed by the user and automatically update the ActiveShade preview. The following scene changes are supported:

• Create/delete objects (geometry, lights, cameras, etc.);
• Modify object parameters;
• Move/rotate/scale objects;
• Apply/remove/edit object modifiers;
• Hide/unhide objects;
• Apply materials on objects;
• Modify material properties like textures, colors etc;
• Modify light properties (like position, color, etc.)
• Animation of cameras, objects, lights and materials (scrubbing the time slider);
• Render settings change;
• Camera/view orientation change;
• Modify camera/view parameters;
• Environment change (color, texture etc).

Geometry
The following geometric objects are supported by V-Ray RT:

• Triangle meshes;
• All other primitives that are convertible to triangle meshes (NURBS surfaces, patches, etc.);
• VRayPlane objects.

Materials
The following materials are supported by V-Ray RT

• V-Ray materials: VRayMtl, VRayBlendMtl, VRayOverrideMtl, VRayLightMtl and VRay2SidedMtl;
• 3ds Max materials: Multi/sub-object, Standard, Shellac and Blend;
• VRayWrapperMtl material is only partially supported.

Textures
The following textures are supported by V-Ray RT:

• Bitmap textures: PNG, BMP, TGA, JPG, EXR, HDR, SGI, PIC and TIFF file formats;
• Procedural textures: Checker, Noise, Falloff, Speckle, Cellular, Gradient Ramp, Tiles etc;
• Utility textures: Output, Normal bump, Mix, Mask, RGB Multiply, RGB Tint etc;
• V-Ray textures: VRayColor, VRayCompTex, VRayEdgesTex, VRayHDRI, VRaySky and VRayBmpFilter;
• 3rd party textures: the ColorCorrect texture is partially supported (the Gamma and Source parameters).

Illumination
The following methods for illumination are supported by V-Ray RT:

• Indirect (global) illumination:
  • Progressive path tracing as global illumination solution.
• Direct illumination:
  • Standard lights: Spot, Omni and Direct;
    • VRayShadow shadow type for hard and soft shadows;
  • Photometric lights;
  • V-Ray lights: VRayLight (Plane, Sphere and Dome types), VRaySun and VRayIES.
• Environment illumination and image-based lighting (IBL):
  • Either through GI or
  • with a VRayLight in Dome mode with a texture map.

Shading
The following shading effects are supported by V-Ray RT:

• Diffuse materials;
• Bump and normal mapping;
• Transparency;
• Clear reflections and refractions;
• Blurry reflections/refractions:
  • Phong, Blinn and Ward reflection models;
  • Anisotropy;
• Absorption (fog) for refractive materials;
• Layered materials;
• Two-sided (translucent) materials;
• Self-illuminated materials.

Camera effects
V-Ray RT supports the following camera types and camera effects:

• Camera types:
  • Perspective views;
  • Standard cameras;
  • VRayPhysicalCamera.
• Camera effects:
  • Depth-of-field with bokeh effects;
  • Exposure settings and vignetting.
  • Camera distortion

Animation
V-Ray RT supports and reacts to the following animation types:

• Camera animation;
• Object animation (move/rotate/scale; deformations);
• Material animation;
• Lights animation.

Render settings from V-Ray Production
V-Ray RT takes some of the render settings from the production V-Ray renderer, if present:

• Color mapping;
• Override material;
• Camera settings for depth of field (when using perspective views or standard cameras);
• Environment overrides.

Go to downloads section at top of page and choose your installer - x86 for 32 bit operating system x64 for XP x64 or Vista x64 Limitations of the VRay RT Demo: The evaluation demo version of V-Ray RT has the following limitations. These limitations are not present in the full version. 320 x 240 maximum resolution for the ActiveShade preview, whether in a floating window, or in the viewports; Maximum 15 geometric objects in the scene (without limitations to their size); The ActiveShade preview will close automatically after 180 seconds (3 minutes); Maximum 5 ActiveShade sessions per 3ds Max session are permitted; DR is limited to two render servers - these can be either a local render server and one additional machine, or two remote render servers.
