Those materials are definitely not very recent. We changed the extension of our material format to .vrmat sometime in the past year or two. We changed from a binary to xml based format about 4 years ago also, which caused some compatibility issues. There were huge archives of user made materials being passed around, before our own material library grew to the size it is today, it's possible that these older materials are from before our switch to xml.

Hi,
I'm having trouble with the materials I've downloaded from your website.
When applied to geometry they display black and all the texture seems to be pointing to "C:\Users\fpedrogo\Documents\V-Ray Materials"

Plus where can you download VRay express for SU?

Thanks

Yes, basically Vray doesn't know how big to make your texture or in what direction to lay it because it uses SketchUp textures to determine that. And since a color has neither direction nor size it gets all messed up.

That seeemed to do the trick ! thanks a lot for the help !

Anyone with the same problem?

that's weird, not sure what it could be. Did you try contacting support? Are you on any kind of network? If wireless - there may be some connection problems.

Sorry no, GPU can't be used to help speed up the render. Only thing that can help speed things up with vfs 2.0 is distributed rendering on multiple machines.

I think you just need to keep reducing the multiplier on the emmissive layer. It also helps to change the emmissive color to lower saturation and make it a darker value.

Just tested a simple cube using RT with a Titan X GPU and it doesn't work. Like Andy said, for now use CPU and if you access to DR nodes, use them as well.

yes, thanks

Cool birds' song during the cool tutorial video! 😎

This is a UV mapping error. Add a UV Map to your Diffuse layer.

Hi, I bet many have asked or noticed this already- the "reset color" in material editor is greyed out since I installed Vray, now it's hard to revert to original texture after playing around with sliders. Also, my textures was automatically saved and renamed into a temp folder (Chaos Group), not a big deal though..

Have someone figured out how to unlink Vray from overriding my materials control? I appreciate any help, I'm really hoping to get the "reset color" button working again. Thanks a lot!

PS: (to Admin) If this is the wrong section, please move it. thanks!

This is something you should report to the V-ray for SketchUp developers so they can address it.
(Also, it's useful to include V-Ray and SketchUp version when asking questions like this given how different version may act differently.)

I'm new to sketchup and Vray so not really sure but you can try reading this:

http://www.vray.com/vray_for_sketchup/manual/choosing_different_render_engines.shtml

It could be something with the iraddiance map settings

"When Min Rate and Max Rate are too low, "leaking light" happens even if the objects are joined together"..you will find where they talk about this somewhere in the middle

I tried readjusting the physical camera and environment settings like you suggested but i still can't figure out how to get rid of that washed out look..any other suggestions?

@valerostudio said:

Take it one step further and add an arrow so you know which way the front face is facing. Similar to how the icon looks in Max.

Yeah, that works too 😉

Make sure you post some final renders in the Gallery !

They store the preview image as a Base64 string, maybe that's why?

On chaoswebsite link doesn't work

You need to add a map to your diffuse layer so that V-Ray can get the UVW information to apply the material properly.

Youll need to pack the scene and share it with any other designer on a Mac. To do this you can go to Extensions> V-Ray> Pack scene. V-Ray will collect all necessary assets and then place them in a local folder. This is the best way to share the file with another user.

That solved it indeed, Thank you very much. First time I had this problem, from now on I'll be aware of this. Thanks again.

Glad it worked! 👍
