vray and vray rt questions

[3LP]

Other question :

On with base relay vray RT to render the equivalent of the first bounce in Vray production ?

Because, if I render with Brute force as first bounce or irradiance map, I do have some really different results.
My lights and my shader aren't the same based on with first bounce I put.

So, Vray RT will be more like IR or more like Brute force for the first bounce ?
Or will he understand what type of informations we put in vray production ?
The first bounce is a question, but there is also the question of color mapping, but I saw in a earlier reply that RT will understand what type of environment we put in vray production. So may be it does the same for first bounce and color mapping ?

And another one if I may :
Could we see the Render elements inside vray RT allso ? Lets take a simple example : if I want to configure my VrayExtraTex to have a AO pass done with the render, can I see the Render element like in VFB, inside Vray RT ? To only tweak that Render element ?
It would be great! May be the cpu could switch to RT the render element that we a currently viewing. It would be a shame if my cpu is been used for a element that I will not watch because i'm tweaking my sun and have no interest to see the AO pass.

May be I'm to curious and have to wait 2 weeks to have my answers, but i'm very exited about that release

Is there any presentation where we can see RT in action?

I will be posting one soon.

V-Ray RT uses brute force GI for both primary and secondary bounces, regardless of the GI engines selected in the standard V-Ray renderer.

Could we see the Render elements inside vray RT allso ?

V-Ray RT does not support render elements, since their calculation is quite complicated and will only slow it down.

For the ExtraTex RE you could use the RT's material override to test the settings.

I'm wondering about processing over several computers.

Currently, I copy over all my textures locally to every computer when it comes time to render a final image. I found that working from a dedicated texture server has problems such as bottlenecks, and tends to slow down my renderings.

How will Vray RT handle Distributed computing? Will the method be the same/comparable to current Vray DR?

I am curious about the processing over several computers as well. For an example, If I have an interior scene lit with 30 Standard Spots, would 20 opteron 275 cores be enough to work without major refresh delays? I understand that there are many factors involved including materials and such but generally speaking in a scene with out a lot of glass or reflections.

Also, does volume light work with this and if not, is it planned for the future? (This would be huge for us.)

As far as textures are concerned, it works pretty much like the normal V-Ray - they must be accessible to all the render servers either from a shared network place, or locally on each machine.

It depends on how many machines are working; with too many machines, the network itself may become a bottleneck, especially for simple scenes.

Nope, at the moment atmospheric effects are not supported. These are planned for an update though.

what max versions are supported? and how close is the rt result to the vray render?

[vlado]

Currently V-Ray RT has builds for 3ds Max 9, 2008, 2009 and 2010. However, it works much better with 3ds Max 2009/2010 as there is a new API there specifically for tracking scene changes.

I am wondering if vray RT will eventually evolve into a renderer of its own? or if it will remain an activeshade kind of renderer...

Anyone have screenshots at 100% size?

I think RT looks like a good product but I am skeptical of quality... kind of hard to order it without demoing it or at least seeing full size previews. How long does the intro price last, if I may ask... I'd really like to demo the product before buying.

Any comments from people who have small networks or single workstation installs would be helpful. Realtime performance on a 10-50 CPU farm does not equal RT performance on a single Quad core.

Also, can the RT window be "floated" or does it always have to be in four view? Sorry if this is a dumb question, I don't use 3dsmax anymore but RT may be enough to bring me back to it.

Thank you.

Think of RT as a progressive renderer. An image resolves itself overtime. More cpu power, the faster the image will clear. I had tested it on a single 4 core and two 4 core machines over the network, and it worked well. But of course if you have 4 16 core machines it will be much faster. I think the idea of the renderer such as RT is that in a couple of years from now the cpu power will be at such level where we will see it in pure realtime. Right now its a new development which still has lots of way to go.

Yes, it can be placed in a render buffer window.
