Well after a day full of trial and effort I finally got there....

You can make the sun invisible and under the options turn off the affect specular. I'm on Vray 3.4 and I don't remember how it was in 2.0. Maybe something similar..

I'm only a novice at Vray, but it seems that the only way to get a numerical value for the roughness is to create a new "Vray material" from scratch. Here's the manual description of how to control it:

Reverse question - is there a way to exclude 100% transparent material from the material ID render ? Say I have a texture of a tree where the foliage is opaque and an alpha channel masks what's not needed. Material ID still considers the transparent surface as a different material.

When a lot of objects are in background, selection is not optimal.

Thanks

I would do this using Curviloft by Fredo. That way you can easily control all the cross sections, contours etc and let the plugin do the work for you.

Try increasing the "Normal Threshold" in the toon material.

That made it! Thanks a lot. I set it to 0.99

Seems to hit the mark

Or maybe use a blend material? With material A being the tile material and the B material a procedural noise for instance. Haven't experimented with it yet.

Best,

Hi, what are your settings for the background? Is it from the vray sun or do you use a domelight for the background? If you use a domelight make sure in the options to check the reflection on.

Best,

Why not use the free Visualizer? 😉

How do I enable material override?

In your Vray options editor - There's a checkbox in the "Global Switches" section

Oh! I see. Thanks for the useful tip! 😄

Is there no other way to make the 2013 do as I want? Or do I need to try again with a higher version of sk?

with a scene of nearly 200MB, I don't see any easy way around the memory issue. Can you try installing 2016 Make version and only vray 2.0 for SU and see how it goes. I would completely uninstall vray before starting on the new install.

You can ignore this post, I just found a solution.
I copy pasted the whole model in a new Sketchup file.
I guess this removes unused materials.

The little "m" button stands for editing the map of that item. Besides, I found that you don't have to turn the whole sun off, making the whole result dark. You onlt have to get inside the sun map, and turn off shadow

For trees , grass & flowers you have this free one! 😉

Can you post screenshots of the Material Panels for the material in question?

As far as I know not. You can try the beta though. It's already stable and gives good results.

Yeah, that's what I'm using these days.

There are some bumpy tricks! 😉
