V-ray questions

What? The default VRAY unit is an inch?? I thought VRAY was created by europeans.
I'm not sure if it's V-Rays default unit. Damien has claimed it uses the model units. He might be correct in one way, but wrong in another. Sketchup uses inches internally. Always. So if V-Ray uses the SU units, without taking into account the model display settings, that would explain why we have to enter units in inches in V-Ray.
So technically, V-Ray uses the model units. But not from an end user's point of view. -

But not from an end user's point of view.i begin to believe that its actually inches. i began redoing and resized my map in inches 2 inchesx inches or 1 inch by 1 inch and its just fit with the scale. aslo after doing the displacement. they are more exact in inches (2.54 cm)even though my measurement that im using is cm and not inches.

Yea, in V-Ray you have to use inches.

Okay new Vray glitch...
I have a .skp model on one machine complete with materials and they are optimised for vray, however if I try open that model on another computer there are no materails in the vray material dialogue...am I missing something?
-
Hm... I tried loading the same file twice on the same computer, and I saw no issues. I'll see if I can install the trial on my other computer and try to open on two separate machines.
-
Thank you very much, I would not bother but I have a model that took me ages to make before my computer died of a static shock, fortunately I had saved it to my server but now i't's useless as it has over 70 textures yet in Vray it only shows one.
-
Hm.. Sounds like a bug. You could send the model to ASGVis and have them take a look at it.
What you could do, if most the materials where plain material with only a diffuse layer, is delete the V-Ray attributes in the model and then reload the model. That might force V-Ray to reread the materials.
-
I doubt it's a model bug as all my models that I have previously modelled and rendered with Vray have the same issue.
The model in question had more than diffuse I had bumps, reflections, etc.
I think it may be a texture mapping issue, a mydamhihad it's texture folder in a different location to my new one.

Damien, thank you for taking the time out to explain some of the technicalities of Vray and welcome to SCF.
It's always a good thing when developers are able to consult and advise on open forum, I know you are very active at ASGvis and glad you have also 'broken the seal' here too.My next question is regarding displacement (I'm sure that this is a well covered subject on the vray site, but for those who are new or in a deciding capacity as far as render engines goes I will ask my questions here)
I have been trying to master displacement on simple objects before using it on any real projects, I have noticed that it totally kills render times which is expected and in line with most other render apps. I have found a few strange behaviors however, below is a simple SU model with a grass displacement on it, it rendered perfectly the first time but when iI decided to add the white band the render was flat without any displacement, I then made the band a group and rendered and it worked again giving me the result below. My question is... does the grouping of two material adjacent to another where one is displaced and the other not have any significance?

Hi,
There is anyway that you put for all the settings for this excellent way to make grass in your worm. Kind to step by step to make displacement. I look in the web and asgvis and is not very clear how I can get this awesome results, Please need help ASAP with this I have a presentation in my college.
thanks.

I'd love to but I unfortunately was using a trial version which has expired a long time ago, I'm sure that one of the many Vray guys here will be able to help.

Hi SOLO,
Thank you for your quick response, I've try and try for 6 hours with many options and I not close to this results. I post the help in ASGVIS forum and I hope someone come out with the exact help.
Also are you the same guy in the PODIUM forum? I am there since they started the soft.Kalu.
PS. PLEASE any help ASAP I appreciate!!!!!!!
-
Kalu, I'm sure someone there will be around soon enough to give more help.
Yes, that's me.

just got a chance to read through this thread...Solo, have you solved your recent problem? I am not sure if i am understanding this completely but it sounds like you took a model to a new computer correct? Vray is very similar to the way autocad handles xreferences (if that sounds familiar?) and you need to have the root files in the original location that they were when you first applied them. I hope that helps?
-
Steelers, I did actually solve it, but that's in the past as I was running the trial version, maybe when the economy picks up or I will look into spending the money to buy Vray 2.

Last one for the displacement tests, using a single face (no thickness) with a texture and displacement.
I believe displacement is under the belt, now the next thing I need to get a grip of is D.O.F, anyone got any good tips that can help?
Hi there SOLO, first off, really great results there,
second would you mind sharing the SKP of the rug also so i can dissect the vray settings and the disp image?? -
Rachid, I will take a look for it tommorrow (it's on an old machine)

hey thnx mate, don't worry i don't mind the wait,
they say "great things come to those who wait"
so i do qualify for that hahaha
thnx again mate -
how can i get rid of that white spots? im using irradiance as primary and light cache as secondary engine everything else as default settings.
-
A quick-fix is to Clamp Colors under Color Mapping.

Rachid, I cannot seem to find that carpet scene any more, I can give you the maps however, in the zip file is a normal, diffuse, specular and displacement map.
