Baking multiple objects onto the first object UV

[juanjo_bernabeu]

Hi team,

I'm very newbie on the baking to texture side but I have a projection mapping project and we are researching on different techniques.

One of those are unwrapping the face (image attached) to make more flexible and able to track points on Unity side but the problem is the next:



Exist any way to bake multiple geometry on one object UV?
In other words, if you see the attached image you can view the diffuse texture occluded by the sphere shadow, but the sphere visibility is not there, only his shadow.

How can I make to render this sphere shape in the unwrapped texture too?

Other example is if I want to bake particles onto her face with this technique. Exist or not the possibility? I'm breaking my head making tests but without look.

Thanks for your attention and sorry for my english.

Unfortunately we don't have a way to do this right now.

Thanks Vlado.

And batch baking to take profit of deadline?. Because I'm trying to make a batch render but it does't work. Script editor says:

Batch baking should work fine. Are you baking through "render.exe" (Maya batch) or V-Ray Standalone?

Maya Batch.

If you did on lighting/shading>bake vray... works perfect as it can be made it by selecting object you want, but if you did on batch render, it does not work, maybe because you need to select an object?

I'm on Maya 2015 Vray 3.0.0.

I have the opportunity in the study up to 2016 and Vray Maya 3.1. Is there new features in this field that can improve this process?

Thanks for your attention Vlado.

For batch mode, we have the following command-line switches:

-bake_node (which node to bake)
-bake_map (name of UV set to bake)
-bake_padding (how many pixels to pad)

How do you pass these command line switches to the render?

We need to do texture baking quite often, and ideally I would put these job on the farm using deadline, but I could not find documentation for this.

There is no documentation page on that subject but you could get it via the following command:

"C:\Program Files\Autodesk\Maya2016\bin\Render.exe" -r vray -h
