Vray in Rhino?


#21

CLONEOPS- Well there’s been a lot of demand for this plugin, so we’ve been giving it a good bit of attention, but the first priority is making sure that V-Ray for Rhino is as bug free and intuiative as possible. We’ll probably be releasing a basic version of the converter that will convert just basic V-Ray materials. The biggest issue is trying to get the procedural maps to convert. V-Ray for Rhino doesn’t have all of the procedural types that Max has.

My fingers are crossed that we’ll have something ready by the end of the month, but a deadline hasn’t been explicitly set yet. The added functionallity of the other map types may take a bit longer. Hang in there, and keep checking our site for updates!

[font=Verdana][size=2]PaulS2- I’ve sent you an email, please send over your sample scene when you get a chance. [/font][/size]

As far as a sample scene that we know works, there’s actually a material test scene that we use that should already be set up and ready to go. It can be found at http://www.asgvis.com/index.php?option=com_smf&Itemid=90&topic=890. If that scene doesn’t help, I can try to get the guys to come up with another test scene for you to work with if need be.

That one works fine…I can add in a light to that material tester scene and I see shadows which are cast from it. All of the general toggles (both hidden and default lights turned off -shadows on) are the same as what I have been using so this is a real puzzlement.

Thanks for pointing me to it.

I could not leave it alone and after another 1/2 hr have figured it out.

The combo of environment on (giving me shadow which gave the appearance everything was normal) and physical camera (default when creating a new scene) with ‘exposure’ check-box active forced any new light coming into the the scene a muliplier figure of around 150!! Turning off the check-box on ‘exposure’ allowed for lights with a multiplier of ‘1’ to behave correctly.

So in fact every light I added into the scene before was working correctly but the intensity was way too low for the settings as they were.

Problem solved.

Arachnode and Paul.S …using the scene just mentioned and downloaded…(by the way winzip errors out on it but "STuffit v9 "works,):shrug:
In Rhino4 demo and Vray for rhino demo the shadows do not show up if I use physical camera in the scene i believe the fstop settings etc effectively burn out the shadow…somehow…i did not explore this further or tweak the fstop/other settings.
using just default camera shadows show up with spotlight.
I fiddled with the skylight /Gi in this file at original settings and had to pump up the lighting settings to 1000 to get any visible render and get a background to show up once i knocked the walls down in the scene cube/walls.I probably missed something else but i am working in between here.:slight_smile:


#25

Very good…I think we were both concluding the same thing at about the same time:-)

For first time tryers, I suggest you (Vray4Rhino developers) change the default opening settings. It can confuse the hell out of people why things aren’t working the way they think they should.

My biggest confusion was seeing a standard spot light with multiplier settings in standard Rhino Render, render with shadows…then the exact same scene in Vray, my light was gone but only the environment illuminated the scene (giving the appearance of a hidden light as it cast it’s own shadow). In fact my light was not gone…it was just way too dim to even be seen slightly.


#26

Well that sucked an hour of my time away:)Weeeeeeeeee…:slight_smile:
anyway that’s done then.
next.-remake that material test object.somethiink wiff fins an gizmoes an such.


#27

No worries its what I do best! Still waiting for you to upload that avatar!

:slight_smile:

I’m hating Vray at this very momment. I cannot seem to get the decay to work for my. i always have to juice the modifier… it just doesnt feel right to have a modifier on 1000 just to get light (and its only on inverse :shrug:).

I’m sure it’s nto big deal but with this lack of sleep it would atleast be nice to see a cone like in max that actually tells me instead of billions of shitty test renders just to understand the scene…:banghead:… just venting.

It’s going to be a long night :curious:

Hey guys, sorry I wasn’t around yesterday. I was working on another type of exporter for V-Ray :). I’m hoping to be able to get both the material exporter, as well as this other exporter for max released around the same time, so it’s been a bit hectic.

PaulS2- Default settings has been a rather hot topic. Almost every person that uses our plugin has an opinion of how the default settings should be set, and unfortunately, it makes it rather difficult to decide which people’s preferences we should cater to. We’ve tweaked the default settings quite a bit, to end up where it’s at now, and just like yourself, there’s a few other folks out there that feel those settings don’t quite fit their needs. So we finally decided to just let you save out your own settings, and share them with whoever you want. There’s a couple settings that come with the plugin by default, they should have the file extension of .visopt. By default they should be in your C:\Program Files\ASGvis\Options folder on your hard drive. The presets that come by default are:

  • default.visopt
  • gi_irmap_high.visopt
  • gi_irmap_low.visopt
  • gi_irmap_medium.visopt
  • gi_irmap_very_high.visopt
  • gi_irmap_very_low.visopt
  • gi_qmc_lc_high.visopt
  • gi_qmc_lc_low.visopt
  • gi_qmc_lc_medium.visopt
  • gi_qmc_lc_very_high.visopt
  • gi_qmc_lc_very_low.visopt

If none of those fit your needs, by all means set the settings to how you like them, and then click File->Save in your V-Ray Render Options in Rhino.

If you’d like us to change or add something to our products though, and I hate to sound like a broken record, you’ll need to say something about it on our forum http://www.asgvis.com .

  1. We are notified every time something is posted, so we don’t need to scour the web for questions on one forum or another. (that means less time spent on searching for suggestions, more time developing.)

  2. Other users on that forum should know how to answer your questions, so you may actually end up getting your question answered a lot faster that way.

  3. If someone else using our product has a similar question, they’d have to look all over the web to find the answer, but if you post it on our forum, there’ll be a centralized location to go for any questions you have about V-Ray for Rhino.

  4. Someone might have already posted something similar or answered your question. Just as I’m sure you’ve seen on this forum, often when someone asks a question, and it’s already been answered, that person will have a reply to their post saying something like “search the forum, then ask the question”.

  5. Helps with bug tracking

  6. We post announcements on our forum, so you’ll find out about new products, patches, upgrades, etc.

The list could go on for a while longer, but I think you’ll see my point. And again, I don’t mean to say this in a negative manner, so please don’t misunderstand. I’m just trying to point you guys toward the resources that will aide you in the most effective manner.

Now as far as changing the default settings goes, the main issue from what I understand, is a lack of knowing how the plugin works, and what the settings do, and how they interact with each other. There’s some adjustments that could be made to the settings, but then again, what application couldn’t use some tweaking. I’m fairly confident that once we release some more detailed documentation, most of the issues folks have with the render options, whether default or otherwise, will be cleared up. It’s just fustrating when what you need to do is on the tip of your tongue, but you can’t quite find the right place to impliment it. All I can say is hang in there, and stay tuned to our site for further updates about documentation.

CLONEOPS- Haha, so you want to ‘pimp my mats’? Sounds like fun. The reason the test material scene is so simple, is just so that you can see the difference between one material or another, in a controlled environment. Just like with the guys over at www.vray-materials.de , we’ve found that really this is the best way to display material sample renders. Having options to choose other test scenes to see how certain materials work with different shaped geometry, may prove to be useful. I’ll keep it in mind for the future!

tilite- Didn’t realize that I hadn’t uploaded my avatar yet. Ya gotta love Mr. Bumbles the abominable snowmonster! Yes having some sort of invisible geometry to represent the light’s actual properties would be useful, unfortunately Rhino is a tad behind the times when it comes to some things (which is why we’re trying to develop for it, so it’s up to par with the big boys). As far as the multiplier being at 1000… http://www.asgvis.com/index.php?option=com_smf&Itemid=90&topic=453.msg2392#msg2392 … hopefully that will help. If not, here’s some more tutorials… http://www.asgvis.com/index.php?option=com_content&task=blogsection&id=5&Itemid=55 . Have Fun!!

Good deal…thanks!

Hey guys, just thought I’d give you guys a heads up!

Does vray for rhino has it’s own tesselator? - hopefully one that kicks
in at rendertime?
I haven’t used vray but i’m quite familiar with mental ray, and to me it’s very nice to be
able to tesselate at render time, without being forced to keep the render meshes inside the file-which already has some 150mb.


#32

q_vazk- V-Ray does tesselate when using displacement, but during a typical render, Rhino will tesselate the geometry, and then pass it off to V-Ray to render. That’s how it works for Rhino, but there might be different methods used by the other folks that have ported V-Ray to various other 3d apps, such as 3D Studio Max. I would assume they’re using methods similar to ours, but I can’t really say for sure.


#33

Oh, and by the way, the material studio that is available for download at http://www.asgvis.com will allow you to create V-Ray materials outside of your 3D apps, and then you can import them into either V-Ray for Rhino or V-Ray for Sketchup. It’s simple and fun to play with. Best of all, it’s free!


#34

Just a note:
I installed vray for rhino in VMWARE fusion while still in osx…
Went well, crashed due to emulation and memory restriction but I did managed to render a
few test shots. This was two days ago. Today, as I switched to boorcamp i remained shocked to find out that my evaluation expired - and of course, nothing worked to try and make it valid again.


#35

q_vazk- Sorry it took so long for me to get back to you about this. I was camping in the middle of the woods all weekend, and unfortunately had no computer access. Now I’m back and to the rescue!! The problem is basically that lots of folks when they come to the end of a demo piece of software, whatever it may be, often want to try to extend that demo or trial period. So there’s something in place to prevent things like setting your system time to another date, uninstalling and reinstalling the software, and a few other methods, from extending the trial date. The problem is that InstallSheild’s way of doing things is sometimes a little too strict. If you lock something down too much, it’s just going to make people want to crack the security just so they can use the software as originally intended.

For the most part, the way InstallShield handles the protection is fine, but occasionally an issue like this can occur. All you did was reinstall you OS, but since it was a major system change, InstallSheild may not have liked what was going on too much, so you got locked out.

We’re working on trying to migrate to a different licensing method so we can wash our hands of InstallSheild as much as possible, but until that method is implimented and well tested, we’re going to have to stick with InstallShield. So for now, if you encounter any message saying that your license has expired with either the demo or full version of software, it just means that InstallShield thought something fishy was going on, and locked you down. You should really only see something like this happen if you make a major system change that may have comprimised the license, so it’s usually not something anyone would encounter unless they were outside of their license agreement.

If you feel that your trial has been cut short, by all means please contact us at support@asgvis.com with a description of your problem, and we’ll be more than happy to help you out.


#36

Hey everybody! I just wanted to drop by and give you all a heads up. The V-Ray for Rhino manual that we’ve been working on is complete and available to anyone that registers on our site http://www.asgvis.com. It’s in pdf format, and it should help a lot of you guys out with any fustration you’ve had with the learning curve.

For those of you that have a hard time finding it, here’s a direct link: http://www.asgvis.com/index.php?option=com_docman&task=doc_download&gid=39&Itemid=72

Enjoy!
