SketchUp & Vray Expert needed

[Albion Man]

Hi,

OK, I'm here at gone 2.pm and and pulling out what little is left of my hair!
I am trying to add people and other items to my scene.
I have saved the PNGs and the corresponding alpha channel.
But when I render there is always a faint (blue?) line showing at the edges of the face I have textured.
I have checked them in Photoshop ensuring all the edges are transparent pixels.
I have tried moving the lines inward slightly to come in tight on the image.
Still no joy!

I have attached an image so you can see what I am talking about.
Hope someone can help me.

Thanks.

It is the transparent pixels themselves that's like that. Don't have a link at hand - but there is a trick to avoid that. (sorry - I go to run don't have time to explain. should be some thread in ASGVis forum.)

i suspect there are still black pixels left at the edges of your alpha channel. you can check it in your photo editing software.

Hi,

Sorry for the delay in replying I had to meet a deadline.

I gave up in the end and used the silhouette people provided in SketchUp.
Simply coloured them white with a 50% transparency setting.
It worked out quite well, but I still wasted a lot of time trying to find a solution to the annoying blue fringe of pixels that showed up.
As I said, I checked them in Photoshop ensuring all the edges are transparent pixels.

If anyone can tell me how to solve this problem I would appreciate it.
I have attached another picture showing a man and tree with this annoying problem.
I have also attached another image showing the final image I was working on.

Regards
Albion Man

Hi thomthom,

Thanks for those links.
Nice to know there is a solution to this problem.

I had a quick look at the ASGvis forums concerning some other topics.
Think I will stay away from the new updated version of Vray for a while.
Looks like they still have quite a few wrinkles to sort out.

Are you an official beta tester?
What do you think of the new version?

One other thing, I am looking for a good grass material for vray.
The type I am looking for is shown here:

But the link is broken.
Do you have any idea where I can get it from?

Sorry to pose these questions here but this forum is much more user friendly than the ASGvis one.

Thanks.

Yes - I've been a beta tester since the beta first started up.
There are some issues - yes. I had originally planned to stay with 1.05.30 until the patch came out, but I had a model at the office that took ages to parse with the old version - and the new parsed it so quickly that I risked it. So far it's been going fine with only minor hickups. I've been working with simple clean new scenes - not any existing ones - so that has probably made be avoid many of the issues.

But this release is generally very good. When the patch comes out it'll be brilliant. V-Ray materials follow the Sketchup materials so we can copy between models and make components with V-Ray materials already set up. AO, render frame, IES and alpha channel support are great additions.
