در این قسمت میتونید لایه های مختلف تصویر رو جدا جدا رندر بگیربد و در برنامه هایی مثل Photoshop یا AfterEffect اونها رو با هم ادقام کنید یا برای اصلاح یا تشدید برخی کانالها استفاده کنید .
مثلاً اعمال عمق تصویر در رندر نهایی و یا اصلاح مقدار انعکاسات در رندر .
سلام
رندر المنت ها به درد کامپوزیت میخوره
المنت ها لایه های مختلف تشکیل دهنده رندر نهایی شماست ، مثل : دفیوز ، رفلکت و...
حالا موتور وی ری هم از این نوع رندر پشتیبانی میکنه
یه توضیحاتی هم درباره هر کدوم از این المنت های وی ری توی این سایت داده شده www.jironomo.com/vray-render-elements.php
In this tutorial I will explain exactly what each individual vray render element does and how to set up the vray render elements in your vray render settings. I will then go on to explain explain how we use some of those elements in post production to tweak our images. This can save you a lot of time re-rendering images if you are not happy with a certain element (reflection, colour etc) you can use a few tricks in photoshop (see the photoshop layers masks and compositing tutorial) and the various vray render element images to adjust your final image without having to re-render!
What are the vray render elements?
The vray render elements basically allow you to seperate the different visual information available in a 3d rendering into seperate images. It is then possible to use photoshop to use these various elements to tweak specific parts of your rendering.
Here is a list of all the vray render elements available in vray 1.5 and a brief description of what they do:
Vray Alpha - Alpha transparency
Vray Atmosphere - The atmospheric effects
VRayBackground - The image background
VRayCaustics - The caustics on the material. Only present when the Caustics option of V-Ray is enabled. This channel does not include GI caustics
VRayDiffuseFilter - The pure diffuse surface color. Note that this is different from the standard 3ds Max Diffuse render element, which contains the diffuse surface lighting
VRayGlobalIllumination - The diffuse surface global illumination
VRayLighting - The diffuse direct surface lighting
VRayMtlID - The material ID of the object
VRayMtlSelect - This element allows you write the result of a V-Ray compatible material into a separate element
VRayNormals - The surface normals
VRayObjectID - The object gbuffer ID
VRayRawGlobalIllumination - The raw diffuse global illumination (not multiplied by the diffuse surface color
VRayRawLighting - The raw diffuse direct illumination before it's multiplied by the diffuse surface color
VRayRawReflection - The pure surface reflection before it's multiplied by the reflection filter color
VRayRawRefraction - The pure surface refraction before it's multiplied by the refraction filter color
VRayRawShadow - The raw light that was blocked by other objects
VRayReflection - The reflections on the surface
VRayReflectionFilter - The reflection filter (the color by which the raw reflections are multiplied to give the final surface reflection). This may be considered as an alpha channel for the reflections
VRayRefraction - The refractions on the surface
VRayRefractionFilter - The refraction filter (the color by which the raw refractions are multiplied to give the final surface refraction). This may be considered as an alpha channel for the refractions
VRayRenderID - The node render ID of the object that contributes most to the pixel value
VRaySelfIllumination - The self-illumination of the surface
VRayShadow - The diffuse light that was blocked by other objects
VRaySpecular - The surface specular hilights
VRayUnclampedColor - The unclamped image color
VRaySamplerRate - Shows an image where the pixel brightness is directly proportional to the number of samples taken at this pixel
VRayExtraTex - Renders the entire scene with one texture mapped on all objects
VRayVelocity - The surface velocity. This channel will not be generated if 3d motion blur is enabled
VRayWireColor - The wire color of the object as set in the 3ds Max scene. This can be used to generate masks for the objects based on their wire color
VRayZDepth - The z-depth of the surface
VRaySSS2 - Renders just the subsurface part of the VRaySSS2 material on a separate layer
