[SOLVED]Create new renderdata

Is there a way for creating completly new RenderData?
For exemple set render engine to Hardware seem to broke the UI since we got the interface of the standar render but we don't have parameter for hardware.
Also I'm not able to use some preset or set a custom size.

import c4d
  
def main() :
    rd = c4d.documents.RenderData()
    rd[c4d.RDATA_RENDERENGINE] = c4d.RDATA_RENDERENGINE_PREVIEWHARDWARE #Not working ?
  
    rd[c4d.RDATA_FRAMESEQUENCE] = 2
    rd[c4d.RDATA_PRESET] = c4d.RDATA_PRESET_HDV1080_25#Not working
    rd[c4d.RDATA_XRES_VIRTUAL] = 1920.0#Not working
    rd[c4d.RDATA_YRES_VIRTUAL] = 1080.0#Not working
    rd[c4d.RDATA_FRAMERATE] = 25.0
    rd[c4d.VP_PREVIEWHARDWARE_ENHANCEDOPENGL] = True
    rd[c4d.VP_PREVIEWHARDWARE_SHADOW] = True
    rd[c4d.VP_PREVIEWHARDWARE_POSTEFFECT] = True
    rd[c4d.VP_PREVIEWHARDWARE_NOISE] = True
    rd[c4d.VP_PREVIEWHARDWARE_ANTIALIASING] = 32
    rd[c4d.RDATA_PATH] = "test"
    rd[c4d.RDATA_FORMAT] = c4d.FILTER_JPG
  
    c4d.StopAllThreads()
    doc.InsertRenderData(rd)
    doc.SetActiveRenderData(rd)
    c4d.EventAdd()
  
if __name__=='__main__':
    main()

Hi,

let's go through this one by one:

rd[c4d.RDATA_RENDERENGINE] = c4d.RDATA_RENDERENGINE_PREVIEWHARDWARE #Not working ?

The actual switching of the engine (in the sense of having the combo box change to the HW renderer) should work this way (at least it does here). The problem is, that you still need to manually add the actual video post effect "Hardware OpenGL" to make it work and have the relevant parameters.
I suggest to take a look at the RenderData manual in our C++ documentation. Among others you can find a code snippet that actually switches to the HW preview render.

rd[c4d.RDATA_PRESET] = c4d.RDATA_PRESET_HDV1080_25 #Not working

Unfortunately the presets can not be used in Python (in C++ there might be workarounds using certain messages). The resolution preset does not get stored, instead certain parameters get modified, when the user interacts with the preset menu.

rd[c4d.RDATA_XRES_VIRTUAL] = 1920.0#Not working
rd[c4d.RDATA_YRES_VIRTUAL] = 1080.0#Not working

Here we have two options. Either take a look at the above linked manual page and set the resolution via RDATA_XRES and RDATA_YRES IDs directly, like so:

rd[c4d.RDATA_XRES] = 1920.0
rd[c4d.RDATA_YRES] = 1080.0

Or, if you want to stick to those virtual IDs (for whatever reason), then you need to fake user interaction in order to make it work. Like so:

rd.SetParameter(c4d.RDATA_XRES_VIRTUAL, 1920, c4d.DESCFLAGS_SET_USERINTERACTION)
rd.SetParameter(c4d.RDATA_YRES_VIRTUAL, 1080, c4d.DESCFLAGS_SET_USERINTERACTION)

Thanks you a lot Andreas.
I still don't have the reflex to check C++ but I should.

Here is the correct python code if any other people want it

import c4d
  
def main() :
    rd = c4d.documents.RenderData()
    rd_bc = rd.GetDataInstance()
    
    rd_bc[c4d.RDATA_RENDERENGINE] = c4d.RDATA_RENDERENGINE_PREVIEWHARDWARE
    
    hardware_vp = c4d.BaseList2D(c4d.RDATA_RENDERENGINE_PREVIEWHARDWARE)
    hardware_vp[c4d.VP_PREVIEWHARDWARE_ENHANCEDOPENGL] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_SHADOW] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_POSTEFFECT] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_NOISE] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_TESSELLATION] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_SSAO] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_REFLECTIONS] = True
    hardware_vp[c4d.VP_PREVIEWHARDWARE_ANTIALIASING] = 32
    rd.InsertVideoPost(hardware_vp)
    
    rd_bc[c4d.RDATA_XRES] = 1920
    rd_bc[c4d.RDATA_YRES]  = 1080
    rd_bc[c4d.RDATA_FRAMERATE] = 25
    rd_bc[c4d.RDATA_FORMAT] = c4d.FILTER_JPG
    rd_bc[c4d.RDATA_PATH] = "test"
    
    c4d.StopAllThreads()
    doc.InsertRenderDataLast(rd)
    doc.SetActiveRenderData(rd)
    c4d.EventAdd()
    
if __name__=='__main__':
    main()
