Multiple Modo Environments and V-Ray...

[carsonjones]

I'm wondering if it's possible to treat environments in V-Ray in the same way as we can with Modo. For example I often use one environment to light the scene and set it to not be visible to the camera. I have a second environment that is only visible to the camera and does not light the scene or affect reflections, etc. This is very handy for product shots where you might want a complex HDR to light the product but have the product on a shadowcatcher with a single colour background (e.g. white). Is it possible to set this sort of thing up with Vray for Modo?

Yes, just set it up like you do with MODO's renderer.
It should work in V-Ray for MODO. If not, then it is a bug.

Yes it works like in modo!

Actually, you can do one better than modo's render engine- you can specify environments per material!

Haven't had a chance to test it yet... will the Modo Shadowcatcher work out of the box in V-Ray? If not, is there a V-Ray preset for this, or even a step-by-step? I'm trying to hammer down my product rendering workflow in V-Ray (Modo). Thanks for the input!

The shadow catcher should work, not in RT GPU though, the GPU team are working on this at the moment.

Although there are some problems with it reflecting the environment when EIS is enabled.
Not sure if that would affect you.
I think the behavior is the same in V-Ray for 3ds Max/Maya when you have a textured dome light.
I don't know how this is supposed to be working in general.

Seems that even in CPU RT the shadow catcher does not render correctly (screen capture incl)

.

Here's a screen capture of a very basic scene. Default Modo sphere and default material using default Modo Shadow Catcher. Same result.

This is the issue I mentioned when you have EIS enabled.
Internally a dome light with the env. texture is created in this case and you are seeing the reflection of that dome light.
For these simple environments (no HDR image), you can disable EIS to work around the issue.

For HDR environments, the following setup is used in V-Ray for 3ds Max :

I need to check if this works in V-Ray for MODO.

In any case, we will try to fix the dome light, so it is not seen in shadow catcher reflections,
as the above workaround is pretty complex for a simple setup.

Is there anyway to expose this dome light to the user?

Hi,

is there any update regarding the EIS and the Shadow Catcher?
