Tests with the new Vray

[Geddart]

Hi there,

Let me introduce myself. I'm (almost) 20 years old and i learned 3dsMax by trial and error. Over the time i made many tests to improve my skills and although they can eat up some time, they can teach you a lot. Now i work @ lichtecht.com and we just bought Vray. I got my hands on the new internal version and i have to say it's incredibly cool. (although there are many bugs left)

So do you guys stressed the new Vray Version with some tests yet?
There are many people that dont have this version yet so let's start a Thread with some cool tests we made!

Thats why got so far:



This is a procedural Symbiont Texture that displaces a simple Sphere.
It renders much faster than in the "older" versions of Vray. Congrats Vlado and Peter!



The new VrayFur. There's no SSS on the Sphere. Rendered with direct computation. (to get the small gi-shadows from the Hairs)



Well, this is not that good looking but technically it's impressive!
As you can see on the objects in the front they consist of quite a few polygons. Actually the Scene consists of more than 3 Billion (!!!) Faces.
This was done with the help of VrayMesh and the new dynamic racaster. The objects are copied not instanced. I don't know if it makes a different for Vray though. The scene rendered 15min, but it was not the geometry that stressed Vray the most - it was the Antialising of the fine structures in the back. I rendered with fixed rate. From what i saw the Raycaster works like a charm. I turned the memory limit up to 600mb and it never exceeded this limit. Congrats Vlado and Peter!


Ok, if you have some tests, post them here!

WOW Impressive stuff

[f97ao]

Very cool. Please everyone that has the internal build post more tests

Also how does this new vraymesh object work? Can you have a low proxy version of it and switch smootly back and forward? I always hated the proxy objects in 3dsmax. Also is it possible to say add a modifier above one of these vraymesh objects? Would be very handy if you were to animate a super heavy tower, and you could add a bend modifier ontop of it and animate it.

Glad for any answers

Nice....!!!

The first test is impressive....!!!

Post more test please!!!

[Geddart]

Thanks guys!

@f97ao:
The VrayProxy Object is located in the new Vray Objects Palette.
You can save your Mesh to the .vrmesh which contains texture channels, face material IDs, smoothing groups, normals format. (As you can see in the last picture, smoothing groups doesn't seem to work properly yet.) When you load your mesh you can display it as a bounding box or "from file". (wireframe) When your mesh has more faces than a certain limit it'll just display every n Faces. You can't apply modifiers to the VrayProxy. (i think in this case max would have to load the mesh again and that's what we don't want)



Original - VrayProxy

this is crazy... this is crazy!!!!!

one question... is Vray fur can interact with Wind spacewarp?
maybe not..

[sinner]

what is that NEW VRAY FUR ?

[J_Bug]

From the Current Help Index as of 01-22-04:

VRayFur
General
"VRayFur is a very simple procedural fur plugin. The fur is generated only during render time and is not actually present in the scene."
Notes
"At present the fur has no meaningful representation in the viewport. This will be corrected in future releases.
At present the fur will not generate motion blurred geometry for deforming source objects. This will be corrected in future releases. Camera motion blur is supported.
Avoid applying textures with Object XYZ mapping to the fur. If you need to use a 3d procedural texture, apply a UVW Map modifier to the source object with the option to convert XYZ to UVW coordinates and use explicit mapping for the texture. "

VRayProxy
General
"VRayProxy allows you to import geometry from an external mesh at render time only. The geometry is not present in the 3dsmax scene and does not take any resources. This allows the rendering of scenes with many millions of triangles - more than 3dsmax itself can handle."
Notes
"The mesh generated by the proxy object is not modifiable. Any modifiers applied to the VRayProxy object will be ignored.
If you need to create several proxies linked to the same .vrmesh file, it's better to make them instances - this will save memory since the .vrmesh file will be loaded only once.
Materials are not saved in the .vrmesh file. Instead, the geometry will be rendered with the material applied to the VRayProxy object. This is because third party materials and procedural textures would be difficult to describe in a general way. In addition, you may want to edit the material independently of the mesh.
The resulting .vrmesh files can be rendered outside of 3dsmax - for example, by the standalone version of VRay."

VRayPlane
General
"The VRayPlane is a very simple plugin that implements a procedural infinite plane primitive for VRay. The source code of VRayPlane is also available as part of the VRay Geometry SDK."
Notes
The position of the plane depends on its transformation in the 3dsmax scene.
You can have more than one infinite plane in the scene.
The plane is rendered with the material applied to the VRayPlane object."

OMG GOSU

[sk_fly]

I read that vray fur will be able to work with shag hair to get dynamics and modify it direction and other parameters. Do you know when this will be implemented?

how to save a vraymesh?

how to save a vraymesh?

to load it with Vrayproxy?

please can u explain?

bye and thanks for the eplanation

[corey]

Pengo,

It's best to start with the new help file.

[pengo]

obviously I havent it

I want only know how it works

[corey]

This is what I know.

The VRAYProxy uses the new Vray Geometry SDK. It also makes use of a new .vrmesh file format. The meshes that is created is simplified mesh that is vray renderer ready.

All you do is select the mesh you want to replicate. You then export the selected mesh(s) to *.vrmesh file by using a MaxScript command. A Vray mesh export dialog appears where you are able to select the file loaction, choose single or multiple file export, and you can choose to automatically create proxies.

Then you load the proxy from the Create Panel Standard Primitives / Vray / and selecting VRayProxy. and then click in a viewport. Another dialog box will appear. You simply choose the .vrmesh file you exported.

Something like this anyway.
