Mograph Camera Shader from Python
fasteffect last edited by m_adam
I'm trying to write a script to add the mograph camera shader to the luminance channel of a material, and then set the Camera target. I can insert other shaders, but I cannot locate in the documentation the correct way to instantiate that shader, nor how to modify the property of a shader once added to the material.

here's an example on how to create a camera shader and set the link of the camera.
Be aware you need to create the shader using it's ID so it could be changed in the future.
I've used a script from @m_adam as a base and just added the camera shader stuff. You can thanks him a lot ^^
import c4d from c4d import gui def main(): # Gets the active object if op is None: raise ValueError("op is none, please select one object.") # Retrieves the BaseDraw of Render View bd = doc.GetRenderBaseDraw() if bd is None: raise ValueError("no BaseDraw found") # Retrieves the scene camera cam = bd.GetSceneCamera(doc) if cam is None: raise ValueError("there's no camera") # Creates a default Cinema 4D Material, the created material only exist in the memory mat = c4d.BaseMaterial(c4d.Mmaterial) if mat is None: raise RuntimeError("Failed to creates a new BaseMaterial.") # Inserts the material in the active document doc.InsertMaterial(mat) # Creates the Camera Shader #be aware you have to use the ID here but it can changed in future release sha = c4d.BaseList2D(440000050) if sha is None: raise RuntimeError("Failed to creates a bitmap shader.") # Defines the camera link inside the shader sha[c4d.MGCAMERASHADER_LINK] = cam # Inserts the shader into the material mat[c4d.MATERIAL_COLOR_SHADER] = sha mat.InsertShader(sha) # Checks if there is already a texture tag on the active object, if not creates it textureTag = op.GetTag(c4d.Ttexture) if not textureTag: textureTag = op.MakeTag(c4d.Ttexture) # If the texture tag is not available at this point, something went wrong if textureTag is None: raise RuntimeError("Failed to retrieves the texture tag.") # Links the newly created material from the textureTag Material link parameter textureTag[c4d.TEXTURETAG_MATERIAL] = mat # Changes the texture tag projection to UVW textureTag[c4d.TEXTURETAG_PROJECTION] = c4d.TEXTURETAG_PROJECTION_UVW # Informs Cinema 4D something changed in the scene c4d.EventAdd() # Execute main() if __name__=='__main__': main()

Thanks that worked perfectly. I thank you both!
