i use vay for su 1.0...how can i upgrade it???
pls help.
i want to use sr1.5 as soon as possible.....
Follow the link from this announcement: http://asgvis.com/index.php?option=com_smf&Itemid=90&topic=5167.0
Just run the installer and I'll do the upgrade for you.
An update to this:
This also occurs in SketchUp 7.
And I've realised that the components isn't missing, but instead it's the position of the copies that's incorrect. They all end up in the position of the original.
Do you need any examples? Or do you have what's needed?
Is that blue material a material you've created? Or just the default SU backside? Ideally to avoid oddities, don't rely on the default SketchUp material. From your render it looks like you have the SU backside showing in the model, but the mirror reflects the front face colour. ...I could be wrong though... Hard to tell without actually investigating the scene.
Not sure what you mean by pixeling, but if you refer to the noise in the image it's most likely due to the QMC being used for primary light bounces. If you change to Irrandiance Map it'll be smoother and render quicker.
The brick wall reflection is odd. Is there actually a texture applied to that side. HArd to tell since it's in the shadows.
If you posted the file it'd be easier to tell what's happening.
The forums over at ASGVis, http://www.asgvis.com is great. Really helpful people there. I picked up V-Ray about a year ago now. Have used it for a few projects now and then. V-Ray is a bit baffling with all the options to begin with, but eventually you pick up what controls what.
This occurs in SU6 and SU7.
When you import a 3DS model the backface UV mapping is incorrect. For instance, I got a bunch of XFrog trees. Leaf texture are mapped to a plane. On the front face it's correct, but on the back side it's incorrect scale and rotation. Import in any other program and it looks ok.
It's a major show stopper.

Do you know where can i download a free version of the vray for SU sr1.5 ¿?
The tip ´bout the light that you gave worked perfectly. Unfurtunately didn´t have the same luck with the reflective efect.
In the image i'm working with no GI and wanted to have a mirror efect in the grey wall but it's not showing off.
I'am having serious problems creating mirror and pullished metal.
Please some advise.
Thanks again.
The SR1.5 is a free upgrade from your old version.
By default when you add a reflection layer in V-Ray it creates a Fresnel reflection. You can see the capital M next to the colour in the reflection layer. Click that M and choose none in the map type. Then the reflection is even, determined by the colour value in the reflection layer. Set it to white for complete mirror.
Also, the docs says that if the example
=SMALLEST(CURRENT("LenX"),20, 10)
was put into the LenX value it'd restrict it. Or am I reading it completely wrong?
Yes, there's a Service Release availible. Info and download link here: http://asgvis.com/index.php?option=com_smf&Itemid=90&topic=5167.0
As for your scene:
Emmisive materials needs a high multiplier when you use the Physical Camera. In the original version, which you have, it could easily be 20000-40000. In the SR release it's much less, down to the tens.
Reflection, you don't see any reflection because you don't have anything to reflect. You have a box and a cylinder floating in empty space. Don't be fooled by the SketchUp ground, that's just a Style effect and V-Ray has no clue about that.
You either need to model some surroundings, or use a 360 degree image for your Enviroment Background.
So there is no way to let the user see that the value has been corrected?
There's a DC forum?
...or do you refer to the normal Component forum?
Could be a graphic card issue if the app makes use of the card for the calculations... Just guessing here...
I've got a custom Angle attribute for my DC.
It's set to:
Units: Decimal Number
Display rule: Users can edit as textbox
Display label: Angle
Display in: Degrees
Then to limit the values to a max of 360 I use this formula to Angle:
=SMALLEST(CURRENT("Angle"),360)
The problem is that when I type a value in the DC Option window the formula disappears and gets replaced by the value I entered in the Option Window.
Maybe I read the docs wrong: http://sketchup.google.com/support/bin/answer.py?answer=114561

SMALLEST(value1,value2,...valueN)
The SMALLEST function returns the smallest of the values in a list.
Example:
=SMALLEST(CURRENT("LenX"),20, 10)
The previous example, when entered into the LenX value field, constrains the component so it cannot be scaled less than the smallest number (the value of LenX, 20, or 10).
But from that I thought I could do just what I did with the Angle attribute...
p.s. Is there a different section of the forum DC related topics should be posted in? The Component section didn't seem fitting as it looked like more for sharing components...
Ah.
I reset the component and now all the custom Attributes are gone.
Thanks for clearing that up.
I just noticed that if I ever created a custom attribute for a DC component part, remove it, the attribute is still present when I open the DC and select one of the copies.
If I select the original, where the attribute is not seen in the Component Attribute window. Is this a bug or am I missing something when I remove attributes?
I tried to write 6² as 6^2 as in most other scripting languages I've used. But that caused an error. What syntax do you use in DC formulas?
Can you post a screenshot of the scene? It'd make it allot easier to determine what's going on.
Also, what V-Ray version do you have?

I'm not sure how long it will be until we switch to 7, due to the economics of our industry. Will the free version of 7 work ok installed alongside the Pro version of 6?
Yes. 
It's not been consistent. I'll keep observing it and report back.
And what's more: had I tried it directly in SU I wouldn't have had that problem because the SIN function then sakes degrees and not Radians... doh!
