Hi @ktheorin1, thanks for reaching out us and welcome to the Forum. To find all the assets in a given scene you can use the BaseDocument::GetAllAssetsNew() which returns you a list of dictionaries with all the assets contained in a document. The example below retrieves all the textures in the active document and append the string "_replaced" at the end of it def main(): textures = list() # execute the GetAllAssetsNew for the current document c4d.documents.GetAllAssetsNew(doc, False, "", c4d.ASSETDATA_FLAG_TEXTURESONLY, textures) for t in textures: textureOwner = t["owner"] textureURL = maxon.Url(t["filename"]) # get the texture suffix textureSuffix = textureURL.GetSuffix() # remove the suffix from the URL textureURL.ClearSuffix() # replace the name by adding the word "_replaced" textureURL.SetName(textureURL.GetName() + "_replaced") # set again the suffix to the URL textureURL.SetSuffix(textureSuffix) #update the textureOwner parameter textureOwner[c4d.BITMAPSHADER_FILENAME] = textureURL.GetSystemPath() # notify Cinema about the changes c4d.EventAdd() It's also worthy having a look at the maxon::Url to handy manage the path of the retrieved textures. Cheers, R
