Grant Warwick advanced materials workflow in Vray for Modo + Scene files

Muhammed Thank you for making that video it was very clear, exactly what I needed.

Thanks for the video, it helped me start understanding VRay with nodes. You should post it in the Tips and Tricks section of the Modo forums.

Hi every one, I am trying to do a displacement with Vray, but I cant figure out how it works. Do I have to use the Modo displacement, or is there any specific Vray material that I have to use ?

Hi Muhammed thank you for your answer, I already had a look at the documentation, but unfortunatly that doesnt help me that much, because I already tried what was in the documentation, the displacement didnt worked, but today I wanted to give another tried, and it has worked, it looks like that I had a bug of refresh of the RT renderer when I was working on my material.
Thank you for your help.

Edit : well I do some modification and again it doesnt work. I want to be sure of something, Is there a Vray displacement material ? Or do you just specified that any material is a displacement in the shader tree and change its properties in the Vray Geometry properties.

Yes even without using the geomtry properties..Set surface shading to Displacement like this

Thanks a lot for your help. Now I see my problem, I dont have this Vray Mtl Common option in the shader tree when I select my material, I only have the Vray Geometries properties. Well I have to investigate on that one. Again thank you a lot for your help.

[virtual_francky]

Ok, after investigating further, it looks like that I have a refresh bug with the RT Renderer.

[Muhammed_Hamed]

You are welcome!
The common option properties should be there for any Vray material. You can control,bump,normal mapping and displacement amount there.
What version of Vray are you using? Sometimes you will have to restart RT for changes to take place!

[virtual_francky]

I am using the last nightly. You are right to make it works I have to stop and restart the RT, but for displacement it is always, not sometimes, that's a bit slowing the work. Again thank you for your help and kindness.

I tried it now. I have the same problem too. The IPR is coming soon anyways for 3.5,and it won't have any update problems..also, I'm sure they will work on RT more too.
You are welcome ^^

I don't know where you are getting this.
There is no IPR for V-Ray for MODO, the feature is specific to V-Ray for 3ds Max. So it's not coming to V-Ray for MODO.
Lately V-Ray for Maya has renamed its RT to IPR, but really it's the same thing as the RT in Max and MODO.

And yes, I have logged the issues about RT not updating properly. It will be a gradual process to fix these.

My bad..sorry!
I think I read about it in Maya forum few weeks back and somehow got it mixed with Modo..so embarrassing..stupid me

Hi Muhammed.

Love that video, helped a lot with Grants Lesson..

Question for you. When you mention near the end of the video, "3.5 will have glossy fresnel" , which property in the schematic view are you referring to?

I'm trying to see how to translate your last method into the GGX system in 3.5. The only new property I see for 3.5 is the GGX Tail falloff.

Thank you!
