I added the code to a python tag and Cinema said the code ran without problem, but nothing happened to the dimensions of the plane. Did i miss something obvious?
here is the C4d file..

There are several places where your bitmap can be fund, according to the state of your document (saved or not)or your choice while loading the picture(make a copy or not).
This script should work in any case.
Let me know if not.

Thanks for sticking in here with me.
No joy. Maybe i'm doing something wrong. I dropped this code in a python tag on a plane object with a texture attached. Should that have worked?!
Am i doing something wrong?

Yes, if you use a Python tag, than op is the Python tag and not the assigned object.
You have to use obj= op.GetObject() instead.
Have fun!
Martinlike:
import c4d,os from c4d import gui,bitmaps,storage def main() : obj= op.GetObject() print obj if obj==None:return #not a plane primitive if obj.GetType()!=5168:return doc = c4d.documents.GetActiveDocument() if obj.GetTag(c4d.Ttexture)== None: dialog=gui.MessageDialog("Please assign a material to the object",c4d.GEMB_OK) if dialog== 1: return else: TexTag=obj.GetTag(c4d.Ttexture) Mat= TexTag.GetMaterial() Shader=Mat[c4d.MATERIAL_COLOR_SHADER] print Shader if Shader.GetType() != c4d.Xbitmap: dialog=gui.MessageDialog("Please insert a picture",c4d.GEMB_OK) if dialog== 1: return bitmapPath = Shader[c4d.BITMAPSHADER_FILENAME] #if bitmapPath is´nt absolute if not os.path.dirname(bitmapPath) : #the document has´nt been saved already ->picture in user library if not doc.GetDocumentPath() : abspath= c4d.storage.GeGetStartupWritePath()+"/"+"tex"+"/"+bitmapPath #the picture should be inside the asset´s texture folder else: abspath= doc.GetDocumentPath()+"/"+"tex"+"/"+bitmapPath else: abspath = bitmapPath print abspath bmp = bitmaps.BaseBitmap() if bmp.InitWith(abspath)[0]== c4d.IMAGERESULT_OK: if bmp != None: bmpsize = bmp.GetSize() obj[c4d.PRIM_PLANE_WIDTH]=bmpsize[0] obj[c4d.PRIM_PLANE_HEIGHT]=bmpsize[1] obj.Message(c4d.MSG_UPDATE) #render the Bitmap if you like #bitmaps.ShowBitmap(bmp) if __name__=='__main__': main()p.s.
Don´t use EventAdd() than;) -

Hi,
be sure to use a plane primitive!!
At the beginning of the script we exclude any other objects even a converted plane.
like
#not a plane primitive if obj.GetType()!=5168:returnbecause at the end of the script we want to assign the bitmap size to the primitiv values.
obj[c4d.PRIM_PLANE_WIDTH]=bmpsize[0] obj[c4d.PRIM_PLANE_HEIGHT]=bmpsize[1]If this doesn´t work, post a scene file.

I have been using a plane and i have tired many ways of applying the texture, still no joy.

ok,
you did not use a regular project structure.
The Bitmap is only inside the project folder, but not in a separate "tex" folder like cinema4d usually set it up by default.just create a new folder inside your project folder, name it tex, drag the picture into it and open the scene. works fine!
or
open the scene and safe it again including the asset. works fine!
or
There is a Texture Manager inside cinema4d which shows you every path of every texture in your scene
Adapt the script to your special needs, if you like
Please try to understand those lines by searching the sdk.:abspath= c4d.storage.GeGetStartupWritePath()+"/"+"tex"+"/"+bitmapPathand especially
abspath= doc.GetDocumentPath()+"/"+"tex"+"/"+bitmapPathI implemented a print statement for the abspath already, that you can read it in the console window.
