Its my understanding that RT using GPU in SketchUp is currently not working in 2.0

Why would you ever manipulate a texture outside of the engine? Is that what you are suggesting? You should never have to correct them outside of your engine, my understanding is that you have to tell the engine to correct them because VRay is using 1.0 Gamma.

I just read this tutorial and it is all starting to make more sense to me.

How to setup vray and 3ds max with gamma 2.2? What is linear workflow or LWF? What is it good for?

Based on what is being said here, my guess would be that you should NOT tick those on as long as you have Input Gamma set to 2.2. Although maybe you need to tick them on for Correct RGB? I guess it might be worth a couple of test renders with it on and with it off. If you test it, post your results.

I just have never understood it. All I know is that if I export to EXR and use Linear mapping with clamping turned off, I can get what I need from Photoshop as far as correcting lighting goes.

I'm afraid there is no tool as of yet that does this. I'd recommend you file it as a feature request to QFT: https://bitbucket.org/thomthom/subd/issues/

It'd be a good addition. Or possibly see if Fredo would be interested in looking into if it could be added easily to his JPP.

Skatter works great. You can choose whether you see the grass in SU (not preferable) or only show it when you render. So the viewport stays responsive. And rendering is quite quick as it uses proxies. I noticed that the pursing time for V-Ray takes some more time when using a lot of skatters. You can limit the skatter to only calculate what you see through the camera. You should really try it out and take some time to explore it. It is worth it IMHO.

I hope that OpenSubdiv will improve texture mapping. But I've yet to see - I need to get it hooked up. But I'm hoping that OSD along with WrapR will make a killer combo. 😄

Try sub-dividing your grassy faces into smaller sections, this will help with displacement issues.

Something is messed in V-Ray Options or Material Editor settings. Save your settings first, then go back to the V-Ray default settings and try to render with Override Materials checked and unchecked then. If there is a problem in both you will have to introduce your settings one by one to see which option causes the problem. There is no way around it, I guess.

I actually had a few min to play with it tonight.

1 - Could be an old vismat created with an older version
2- the vismat might be referencing an external texture that is not on your machine, look into the maps and see if they are pointing in the right direction.

Just be aware shep that the actual corner vertices can be creased as well as the edges. You'll get different results if you don't do the corners. If you notice in the gif when I select the crease tool the corners are already red. meaning I have creased them before recording.

It would definitely be possible. You would have to create an "x-ray" style equivalent material in V-Ray and apply it to the component you are trying to highlight to have the effect your looking for. Try the material I've created and attached. Its going to render a bit more slowly, but it should work for what you are trying.

I maybe wasn't clear enough but I would like to use X-Ray one everything except the componen I want to highlight so that it's easier to see. It would be a lot of work if I would have to change all other material in the model to be X-Ray.

So you would need to apply this "xray style" material to everything but the object you would want rendered.

Please email support@chaosgroup.com with this issue.

You have to use TexMix material in the Diffuse slot. Choose Color A slot to load the first texture and Color B slot to load the second texture. Blend them using Color Mix with the alpha texture loaded in Mix map slot. That's it.

Yes! This is high up on the list. It's very annoying then the triangulation disappear as you are working with the mesh.
