Hi @turrican welcome in the plugincafe community. I moved your topic in the correct category and assigned tags, see (How to Post Questions) Please do it for your next topics. Regarding your question, yes it's possible to do it in python. however, I suggest you contact maxon support to report the initial bug regarding the FBX importer. Now you have to keep in mind here we don't code for you but help you to achieve what you want. So the steps in python for doing it are: Loops over each material. Retrieves their name. Create a Bitmap Shader and assign it to the correct channel of the material (normal). To loop over each material, keep in mind that material in Cinema 4D is BaseMaterial which is a child class of GeListNode so to loop over all material use # Retrieve the first material of the current document mat = c4d.documents.GetActiveDocument().GetFirstMaterial() # loop over each material while mat is not None: # Do the things for each mat mat = mat.GetNext() To create a bitmap shader (c4d.Xbitmap) and assign a texture to it find an example in shader_create_bitmap_r13.py. To know the ID of the normal channel, just drop and drop it into the console, see Python Console - Drag and Drop. Cheers, Maxime.

Thanks s_bach very much.

@m_magalhaes said in Retrieve the Surface Point of current RayObject from an arbitrary UV value.: feel free to mark this thread as "solved" how? :) Edit: Solved done :)

@m_adam said in Bake Texture within ObjectData: bakeBmp = c4d.bitmaps.MultipassBitmap(512, 512, c4d.COLORMODE_RGBf) This example helped me a lot. Thank you so much. Regards, Mustapha

@m_adam thanks so using c4d.documents.SaveDocument the window is still showing up.. even with "SAVEDOCUMENTFLAGS_NONE" or "SAVEDOCUMENTFLAGS_AUTOSAVE" could it still be showing up because of an error in the file path its trying to save to or something like that?

hello, If you have nothing to add, this thread will be considered as "solved" tomorrow. Cheers, Manuel

Hi Maxime, thanks for the response! I was aware that the scene gets copied, but unaware of the GetDocument function so it definitely makes sense! I will give that a try and report back. I have been trying this with both a python effector, as well as in a python xpresso node. Andrew

@r_gigante Thank for your professional help! I am so grateful for your commitment!

@mfersaoui said in Automatically add effector object into In-/Exclusion User Data: @m_adam Thank you, Now I'm searching for how to add an Object to an In-Exclude user data. I tried with the following code but this doesn't work. import c4d def main(): effectors = op[c4d.ID_USERDATA,2] # In/Exclude User Data plain = doc.GetFirstObject() # Plain object (Effector) effectors.InsertObject(plain, 1) c4d.EventAdd() if __name__=='__main__': main() The actual issue is that effectors = op[c4d.ID_USERDATA,2] perform a copy of the InExcludeData so that means you have to reassign the data correctly after it since you don't do the change directly from the InExcludeData of the BaseContainer. op[c4d.ID_USERDATA,2] = effector Cheers, Maxime.

Thanks that worked perfectly. I thank you both!

@s_bach Sorry, I just saw your message. the replies notifications was disabled. Thank You!

@m_adam Oh, yes! Thanks, it works just fine.

@m_adam Thank you. Thank you very much！

@m_adam Thank you for another detailed answer !

Hi Maxime, thank you very much! Good to know. I would otherwise searched forever. Cheers, PdZ

Well, I do have a loop but I just pasted the code that would, hopefully, perform the calculation. And I did tried the GetDeformCache approach, but my mistake was, in fact the cloning of the object. Thank you so much for the code, Adam.

@m_adam Sorry about the gaffe. I make sure for it not to happen again. Thanks for your response.

You may want to consider to use scipy. You have to do indexing once, but can the efficiently iterate over the points within a desired radius with the functions that come with the module.

Hi Riccardo, I spoke with SolidAngle. Eventhough the problem has nothing to do with Arnold, they helped us to solve the issue. There is a different behavior on Python when using BaseBitmap and MultipassBitmap for multiple renders. We render thousands of elements from the object tree in C4D. When you reuse a BaseBitmap the depth information will be saved for every element. However when you do the same with a MultipassBitmap, it will only store the depth information for the first element. Strangely this does not apply to the beauty image. The solution is simple. We set up a new MultipassBitmap for every render call. In hindsight, we should have initiated a new bitmap even for the BaseBitmap. Thank you for time, David

Hi rownn, thanks for following up. Can you elaborate more on I wasnt able to get the "customlength" by offset.? Actually looking at your screenshot and assuming that the red-labelled refers to what you actually consider "wrong" and the green-labelled to the right, I think that the red-labelled is indeed correct since it actually lies in the middle of spline considering that the start point is the top/right vertex. At the same time, the green-labelled point is the one that you can obtain when passing 0.5 to SplineHelp::GetPosition() which is the 50% of the spline parametrization not of the spline length. Assuming a linear rectangle is used as shown above the code below shows the behavior I describe: def main(): sh = c4d.utils.SplineHelp() sh.InitSpline(op) splineLength = sh.GetSplineLength() halfLength = splineLength / 2 midPointOffsetIncorrect = halfLength / splineLength midPointOffsetFromReal = sh.GetOffsetFromReal(midPointOffsetIncorrect,0) midPointOffsetFromUnit = sh.GetOffsetFromUnit(halfLength,0) mtx = c4d.Matrix() midpointRed = sh.GetPosition(midPointOffsetFromUnit) # which in this case is the same of offsetFromReal midNullRed = c4d.BaseObject(c4d.Onull) midNullRed[c4d.ID_BASEOBJECT_USECOLOR] = 2 midNullRed[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector(1,0,0) midNullRed[c4d.ID_BASELIST_NAME] = "MidRed" mtx.off = midpointRed midNullRed.SetMg(mtx) midpointGreen = sh.GetPosition(midPointOffsetIncorrect) midNullGreen = c4d.BaseObject(c4d.Onull) midNullGreen[c4d.ID_BASEOBJECT_USECOLOR] = 2 midNullGreen[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector(0,1,0) midNullGreen[c4d.ID_BASELIST_NAME] = "MidGreen" mtx.off = midpointGreen midNullGreen.SetMg(mtx) doc.InsertObject(midNullRed) doc.InsertObject(midNullGreen) c4d.EventAdd() Best, Riccardo
