Vray Vision doesn't reflect material changes

[manishpaul_simon]

Hi there, I was trying to incorporate Vray Vision into my workflow but I guess it still needs some further development. When I added a colour to the color gain or even add color corrections control to a bitmap, it doesn't reflect in Vray vision. I guess I will be sticking to Vray Interactive & try looking at Chaos Vantage for future, unless there's a decent update to Vray vision.

Hi manishpaul_simon,

V-Ray Vision is based on a game engine and in that context supporting the V-Ray shaders complexity (and all the parameters) is close to impossible.
However we are currently working on a new system that is able to 'bake' any texture network into a bitmap data to be used in Vision.
The results we're getting are very promising and we intend to make this available in an upcoming update.
The main limitations of the baking approach are:

• Procedural textures are only samples in a limited UV area which will in some situation lead to visible tiling
• 3D procedurals can not be baked in a reasonable way because they are mesh / UV independent. We can only sample them as 2D maps which again might lead to visible tiling and incorrect texture size.
• Procedural textures which depend on the camera position (falloff) or are based on raytracing (dirt) can not be baked.
• There is a slowdown caused by the baking process...

Note that currently even V-Ray GPU uses this technique internally to handle most procedurals.
Vantage would also have to do something similar to support everything that V-Ray outputs.

Regards,
Konstantin

Hi Konstantin

I would like to express My self about vray visión and what i have found in this Journey vray 5.

When i first saw the vray visión in the beta of vray 5 i was amazed about a real time engine in which we can see our designs.

But suddenly i realized that vray visión wasn't Ready for complex scenes

If i have to tell You the truth i had never used that tool nor vray 5, neither 5.1 and 5.2 since the poor Quality of the tool it takes too much time to load a scene and when it is finally Ready the Quality is so poor that is imposible to see a real space, materials doesnt look right, light and shadows looks like a cartoon.

On another note, reflections and refractions look really bad, when You change something vray visión doesnt work fluidity is slow and doesnt reflect real changes, ( as Manish Paul already said)

I complete understand that this is not the same than vantage ( real raytraced software with great reflections and refractions)

But here is My point...unless we don't get a real update on that is going to be useless again.

On another note when You brought the update 5.1 and 5.2 i almost didnt see any kind of improvement it was almost the same than vray 5.

The Quality didnt improve it, Also between 5.1 and 5.2 with the hotfixes a Lot of the release notes always says improvement on that, improvement on this.

But at the end of time it was almost the same than before the hotfix.

I mean a Lot of the release notes was just visión and visión but this is My concern it is almost the same than vray 5.

And i feel that a Lot of resources just wasted in vray visión and vray visión but i was like ohhh god when i SEE the release notes... Vray visión and vray visión again

But it is impossible to use since this doesnt have any kind of Quality.

On another note vray gpu in interactive mode is going to improve a Lot with the light cache calculated with the gpu...

So unless we don't see a real Quality on vray visión is going to be useless again.

For me is imposible to use it as real time engine and it is Even worst to use it as animation.

So if You are going to improve vray visión i want a real great update on that... Since this takes resources and somethings didnt improve like interactive render, i use all the time interactive render to see lights and materials.

Thanks again Konstantin

Hello, Luis,

Thank you for your sincere feedback!
Firstly, allow me to clear some confusion - the V-Ray Vision developers are a separate team. The progress they make does not come at the expense of V-Ray for SketchUp's development.

In terms of performance you mentioned the main issue is with the long loading time of complex scenes. Beyond that, is there anything else that troubles you in this regard?
Do you feel a need to have a lightweight scene viewer while you work/present your projects or is the workload you put your hardware through a secondary concern?

In terms of quality, procedural texture baking, as Konstantin wrote, will be а noticeable overall improvement. There are a couple more initiatives we may be able to share later on once enough progress is made.
Beside what you shared, can you please rate, let's say, the top 3 visual issues you find most glaring.
To save your time, it would be enough if you are willing to take a screenshot of one of your scenes loaded in Vision and just circle out the specific parts which appearance you are most unsatisfied with.


It will also help us asses your feedback properly if you can share more about the way you use Vision (and the way you think you may find it useful).

1. During which stage(s) of your projects did you use Vision?
2. If improvements for all shortcomings you've found are implemented, which stage(s) of your work process do you think Vision might cover?
3. Have you attempted to use Vision during client meetings?
4. Have you ever used Vision's Standalone Application Export?
5. Production V-Ray rendering aside, on a scale of 1 to 10 where 1 is "Performance" and 10 is "Quality" what do you personally consider more important in real-time viewers such as Vision/Vantage/Enscape?

Again, thank you for sharing your thoughts!

Kind regards,
Peter

Hi Peter

One of the things that i really want is the posibility to do an animation with Quality.

As You already know sketchup is in not the Best software to do animations, 3d max and maya are so much better in this regard.

With the Journey of vray 5 i found that this tool is better for make animations, i believe interactive render is the Best way to see how light, shadows, materials, reflections and refractions looks because i see almost how it is going to be in the production render.

I have never do an animation with vray for sketchup in all My life!!! ( But i really miss that in my work)

1 it takes a Lot of time to render a bunch of images that later i have to use another software to Match the images in order to produce an animation.

2 sketchup is not the Best software to do animations, as You already know sketchup is almost the same than 10 years ago, they do not do anything to really improve the software, but vray is another thing, i'm really happy how Vray has improved over the years, we get with time so many surprises with the major and minor updates ( Also hotfixes are great too)

So i would like to use visión just to produce animations, i believe visión is not going to be the same than interactive render since interactive render is a Ray traced software, but visión is like rasterization.

Vray gpu soon is going to have a better interactive render with the upcoming light cache + brute forcé.

So 2 things in order to use visión: a better representation of materials, better lighting, better shadows, better reflections and better refractions and a faster way to use it.

For complex scenes it takes time to load and Also doesnt move really fast, (Even with 2 2080 ti with nvlink)Also when You have a Lot of effects like the house that i showed to you in the team viewer sometimes i feel doesnt represent the real thing.

So vray visión should be something like lumion right??

I know lumion has a Lot of years for improvement and visión just came 2 years ago.

So vray interactive render for how are going to see the final render and visión to do animations but of course with Quality

That is something that i really miss in vray for sketchup...imagine just doing an animation like lumion...that could be really awesome Peter!!

Right now i don't use visión since the Bad Quality, but seems that with vray 6 this is going to change.

So please make this tool as powerfull as it can be so we can make an animation with vray visión with sketchup with Quality

Thanks again Peter
Best regards

Right now i'm rendering a complex hotel here in México, when i finish that i'm going to try heavy vray visión, just in about like 3 or 4 days more.

On another thing don't forget to bring support for things like displaccement, vray hair material with vray fur, something similar like the complex tonemapping with the VFB, don't forget too normal maps, edges textures, vray dirt.

Thanks again.
