Vray Proxy Trees Free Download

Minimizing Faces in Preview when making a proxy from 10k to 5k did the trick for me, although I am having a problem bending the proxy and rendering it. It shows simply it not being curved. Any ideas why ? 210303_21512764 61.4 KB 210303_31406710 477 KB

i must be missing something here for which i might sound very stupid. i've created a vray proxy and checked automatically create proxy, when the same thing turns on to proxy on the same file i've created it, it works fine showing all the materials assigned but the problem is when i import that proxy in other file or even if i delete that same proxy and again import it, then it shows no materials. i've tried it again and again but can't find the solution:confused:

Just pick the material from the main file and save it in ur library.. (may be u could make a special one for proxy tree or whatever..), and name it as u can remember for that particular proxy file. Now whenever import a proxy file, just apply this material from ur material library and the things will be solved.

What i want to know how to do, how do i change the material ID for the material and geometry (e.g, 1,23 changed to 5, 6, 7....), so that they are all different so that when i import two trees they do not have conflicting material ID's??

because when i brought in the first tree the proxy an materials worked perfectly, but when i brought in the 2nd tree with same materail ID's it said there were duplicate ID's, and the materials to the first tree were applied to the 2nd??

If you want to apply the same sub object materials, i.e. by applying the same material, to two different trees, then you should alter the Material IDs of the model if they appear incorrect. Without ever using them, I would be suprised if the all the Evermotion trees weren't sharing the same material ID assigning convention though.

Thank you very much for the step by step thats perfect, I understand now that material ID's are Object Related, so you can have a number of sub/multi materials with the same materails IDs but they only matter when you apply them to a particular object. Didnt get chance yesterday so i will give it a go tonight. I am Converting from Sketchup & Vray to 3DS Max & Vray and i wish i did it ages ago, putting in 100's of proxy trees etc. Blows sketchup out of the water, just a shame 3DS Max is not as easy and user friendly to quickly model as sketchup. Thanks a Everyone!!!! Yet again Top Forum!!

A good use of the proxy would be in situations in which you wish to add a specific model or set of models (such as furniture, decorations, plants, trees, flowers), and you need to maintain a level of control and customization of the materials (i.e. change materials or modify their look.)

Use case: Import trees as proxies and scatter them around a building. Using proxies also allows you to build a library of assets that can be shared with anyone. Store your models in a custom library folder locally or on a drive or a server.

A good use of the Proxy Scene would be in situations in which you want to prepare and share ready-to-use whole sets of geometry (e.g. living room furniture sets, environment sets like street furniture together with trees), that do not require additional modification or change of materials. Another useful situation is if you would like to split the work between different people/departments.

Use case: Two artists are working on a scene: one on the building, and one on the environment. Exporting and sharing a Proxy Scene of the environment allows you to bring it into the scene with the building without having to set environment materials from scratch.

6. Specify the number of faces in the viewport preview of the proxy if needed (the higher the number of faces, the more detailed the preview). Changing this parameter is not mandatory, you can leave the value at its default.

Note: This automatically switches the asset to High LOD, and if you render with V-Ray Vision, the link to Cosmos will be broken and the special LOD assignment used by Vision will no longer be there. Lower level-of-detail (LOD) versions of the proxy mesh that are used by V-Ray Vision will be lost.

You must to duplicate your tree (with graph, not instance) or reimport it to set the offset.

If you have an animation on 200 frames, you can have 200 differentes offset, but 200 trees not instanced.

I prefer modeling my school architecture projects in Rhino and was wondering where I can find grass and trees for rendering with vray. I've found scatter options with Rhino Grow and a Grasshopper script but I'm wondering where to find proxy objects to scatter. I want to create a meadow with trees, just as a test now that school is out for break.

When a modifier is added, the proxy loses its memory-saving properties and is regarded as just a regular mesh in the scene. Therefore, it is recommended to perform modifications on the original mesh prior to exporting it to vrmesh or alembic and not the VRayProxy object.

Property tags provide a great amount of flexibility with V-Ray Proxy objects by allowing users to template file paths. By using property tags in the Mesh file path, the user can specify different mesh files for each instance of the proxy object.

For example, suppose there are several different tree mesh files with names such as "Willow.vrmesh", "Birch.vrmesh", etc. The user can specify the path in Mesh file as E:\Assets\.vrmesh. Then in the User Defined Object Properties of the V-Ray Proxy object, the value of the tag can be set to any of the mesh file names. For example, asset=Willow or asset=Birch. During rendering, V-Ray evaluates the tag for each instance of the proxy object and loads E:\Assets\Willow.vrmesh or E:\Assets\Birch.vrmesh.

The Alembic layers feature allows modification of a selected alembic proxy by adding layer files on top of it. Each layer transforms the proxy with a different set of properties. These transformations include adding properties to a shape (e.g. UV mapping of an object that has no UVs), overriding properties, adding new objects, pruning objects or properties, replacing an object's (or properties') hierarchy with a new one, etc.

If the proxy has multiple objects in it, when importing as mesh, they are put into a single mesh, resulting in a different structure and coloring. Before using the Import as mesh button, make sure the Export each selected object in a separate file option is selected. It is located in the V-Ray mesh export menu, which can be accessed from V-Ray menu > .vrmesh exporter. This allows for accurate results when mapping with VRayMultiSubTex, Random by element mode.

If Weld vertices in result is checked when importing a proxy as a mesh, the structure and color of the mesh differs from the original. In order to keep the color of the mesh and the original proxy the same, the Weld vertices in result option should be unchecked.

This example demonstrates how the Level multiplier parameter controls proxy rendering at different distances to the camera. When the value is 0.0, no point clouds are loaded. When the value is 1.0, the exact level of detail is loaded for rendering according to the object's distance from the camera. Values between 0.0 and 1.0 bring more detail than specified at the camera distance, while values higher than 1.0 bring less detail than specified.

In older V-Ray versions, UV coordinates in the Alembic file were always imported as mapping channel 0. This meant that in Bitmap textures for materials applied on Alembic proxy objects, you needed to select Vertex Color Channel.

These options control the visibility of a proxy's components when more than one mesh is stored in the same vrmesh or alembic file. The visibility can be controlled either by the objects' names or by object IDs.

The proxy file structure is represented in a tree view with its full hierarchy. You can select individual elements and assign visibility or material overrides. Double click on the hierarchy level labels or click on the arrow icons to expand/collapse the hierarchy.

This rollout becomes active only if the loaded proxy file is in an .abc file format. When enabled, specific ID numbers can be assigned to the existing UV/Color channels and Material IDs. It allows easy modifications on the fly and rendering different variants all at once, without the need of re-exporting the original geometry.

In this example, the alembic proxy file contains different UV/Color sets and Material ID sets. Reorder variants using the arrows. Click on Update preview to apply the changes. To switch between UV/Color sets and shaders sets, use the dropdown menu Mesh set type.

These draft notes reference a PDF file that relates to the workshop held this week on Proxy trees. It also is relevant for and proxy objects developed for V-Ray. Proxy objects are created with a low polygon count to stand in for more detailed objects. They are thus less cumbersome with respect to Rhino files size and rendering performance. A particlarly effective use of Proxy objects is for varied species of trees which can be found in a library stored in the classes/examples folder.

5. Now that the tree is appropriately placed in the Rhino model and scaled, the next step is to add textures. In the V-Ray Asset Editor and under the V-Ray materials palette under the Geometries tab (3rd icond from left in V-Ray Asset Editor) you will find the proxy file listed. On the right hand site its mateial colors are a symbolic majenta and green, not actual for the tree. They need to be correlated with the color of leaves and bark for the tree we are working with and then modified. However, at first we don't know which color corresponds to the leaves and which color corresponds to the bark. 17dc91bb1f
