V-Ray scripting in ruby?

mcekk

Hi everyone,

Is it possible to access methods and/or classes for V-Ray objects through the SU API?
I want to edit the lights, materials and rendering options in an automated way.

So far, I was able to apply geometric transformations to the lights using the following method:

I created a separated .skp file for each of the light objects (rectangle, spot, omni) with fixed parameters. These objects are saved as groups.
I loaded these files as component definitions and created instances as needed.
I applied geom transformations (translations rotations and scaling) to those components to set up the scene.

However I also want to change some parameters of the lighting and the materials from the script. Where is this information stored? Is there a xml file somewhere?

Thanks in advance

SU 2014 + VR2.0

Ill forward your question to the developers and get back to you when I have an answer.

As far as I know, there is no API for VfS.
But the data is stored as XML in the object's attribute. So you can modify it to change the light's properties.

Thanks, Ted and Jiminy for the quick response.
Can I safely edit the file current_skp.xml (located at ASGVIS/VfS), that apparently stores the current global parameters?
Still can't find the light parameters.

Send me a PM and Ill email over a short example from one of the Developers.

Thanks Ted.

no, that file gets overridden when you kick off a render. There are some helper functions we use to manipulate the xml that we store in the attribute dictionaries of the scene, but none of it is very obvious or easy to use for your own purposes. We are also going to be modifying the way a lot of our stuff works over the next couple versions, so if you were to tap in to our xml and play with it, it might not have a very long lifespan.

Thanks for the answer, Devin. Is there another V-Ray implementation where I can animate the illumination? Or I have to wait that this feature comes to SU? I also work with Blender. Thanks in advance.

we currently don't support animated parameters in any portion of V-Ray for SketchUp

I was able to do some short progress modifying the skp files from each light separately and reloading through the ruby script. The only thing that it is still missing is the possibility to render the scene from the script. It is possible to do this from the SU API or from the system? Thanks in advance.

Yes, you can call
VRayForSketchUp.launch_vray_render
VRayForSketchUp.launch_vray_rt_render
VRayForSketchUp.launch_vray_batch_render
