Setting up UDIMs in an Image Tile with python

[ymmanuel]

Hi Ahmed

What is the proper way to set up UDIMS on an Image Tile via python?

I'm able to set all the parameters like the grid, start, digits etc...

but I'm not able to trigger the "Setup the image tiles" button or replicate the functionality via python?
any idea??

Thanks in advance

I think you don't need to access it. Only give correct parameters to define udim file format structure. It does same.

so maybe I'm missing something, here is an script example of how I'm initializing the UDIM tiles, the result is a black image that doesn't work
but if after executing the script I manually click the "Setup image tiles" button it works fine, so the setting seem to be alright

I'm using as guidance the example you showed here

PS: of course in the actual code i use a real image filepath

Code: Select all

import c4d

OCT_UNIVERSAL_SHADER = 1029501
OCT_IMAGE_TILES = 1051204

def main():
    doc = c4d.documents.GetActiveDocument()
    material = c4d.BaseMaterial(OCT_UNIVERSAL_SHADER)
    material.SetName("Test")
    doc.InsertMaterial(material)
    
    texture = c4d.BaseShader(OCT_IMAGE_TILES)
    texture[c4d.ID_BASELIST_NAME] = "Tx_Basecolor"
    
    texture[c4d.IMAGETEXTURE_FILE] = "udim1000.jpg"
    texture[c4d.IMAGETEXTURE_GAMMA] = 2.2
    texture[c4d.IMAGETILES_GRIDSIZE_X] = 3
    texture[c4d.IMAGETILES_GRIDSIZE_Y] = 3
    texture[c4d.IMAGETILES_START] = 1001
    texture[c4d.IMAGETILES_DIGITS] = 4
    texture[c4d.IMAGETILES_FILE_LIST] = "udim1001.jpg, udim1002.jpg, udim1003.jpg\nudim1004.jpg, udim1005.jpg, udim1006.jpg\nudim1007.jpg, udim1008.jpg, udim1009.jpg\n"
    
    material[c4d.OCT_MATERIAL_DIFFUSE_LINK] = texture
    material.InsertShader(texture)
    
    material.Update(True,True)
    c4d.EventAdd(c4d.EVENT_FORCEREDRAW)

# Execute main()
if __name__=='__main__':
    main()
