@zipit work fine thanks a lot

@zipit
In this test, the modification works well, but the cycle button is not updated.
I added c4d.EventAdd(), but in this case it runs in a loop
Test2.c4d

@zipit Thanks. I test and keep you informed

Test.c4d

I have a UserData "MyData" of type Button Cycle and i would like to modify its contents, in python node

Thanks @PluginStudent

In a python node, is it possible to know how many inputs and outputs there are? and their name?

@Cairyn Thanks, all work fine for this module

@PluginStudent
Your link is about the creation of a material (and that I already know how to do), not a render parameter.

But I have tound the solution.

    shader = firstVP[c4d.VP_VRAYBRIDGE_ENVIRONMENT_BACKGROUNDTEX]
    if shader == None:
        shader = c4d.BaseList2D(c4d.Xbitmap)
        firstVP.InsertShader(shader)
        firstVP.GetDataInstance()[c4d.VP_VRAYBRIDGE_ENVIRONMENT_BACKGROUNDTEX] = shader
    shader[c4d.BITMAPSHADER_FILENAME] = "approaching_storm_4k.hdr"

Other question, how to remove it? I don't have found "DeleteShader" or "RemoveShader"

What's wrong in my code?

import c4d

def main():
    # check doc
    if doc is None:
        return

    # get the active RenderData
    activeRD = doc.GetActiveRenderData()
    if activeRD is None:
        return

    # get the first BaseVideoPost (Active Render)
    firstVP = activeRD.GetFirstVideoPost()
    if firstVP is None:
        return
    shader = firstVP[c4d.VP_VRAYBRIDGE_ENVIRONMENT_BACKGROUNDTEX]
    if shader == None:
        shader = c4d.BaseShader(c4d.Xbitmap)
        firstVP.GetDataInstance()[c4d.VP_VRAYBRIDGE_ENVIRONMENT_BACKGROUNDTEX] = shader
    shader[c4d.BITMAPSHADER_FILENAME] = "approaching_storm_4k.hdr"
    c4d.EventAdd()

if __name__=='__main__':
    main()

Thanks to both of you I'll test all this tomorrow and let you know the result.

Hi all

How to change a rendering parameter for an external engine.
For example for VRay:
I know the pluginID. I would like to be able to change the environment parameter from a python xpresso node.

Work fine
Thanks a lot Manuel

Here's the test I took. By putting my script in a python tag on my object, it works. But in an xpresso python node, nothing happens.
Test.c4d

If you delete the tag, keeping only the xpresso node, it doesn't work.

Hi all

Is it possible to deactivate user data or a tab from xpresso?

Hi
I'll need that job too. To be able to refresh xpresso without having to provoke it with a mouse click.

@C4DS
Although a solution has not been given (as I wish to do), explanations have been provided. I have therefore considered it resolved.
For IRL reasons, I could not do so. I will be able to get back to it, and if I find THE solution, I will post it

Hi Sebastian,

Thank you for your response. I found the identifiers of the different VRay materials in the file c4d_symbol.h.
Everything works.
