I have a material with a movie loaded in the Color channel. When I apply the material to an object and set the Editor->Animate Preview option on, scrubbing the timeline, I see the movie playing in the object surface.
However, when I try to get the bitmap from the material, using this python code, it always gets me the first frame, no matter where I have the play-head:
import c4d #Welcome to the world of Python def main() : mat=op[c4d.ID_USERDATA,1] # is there anything in the Link user data? if mat==None: return # is it a Material? if mat.GetType()!=5703: return color_ch=mat[c4d.MATERIAL_USE_COLOR] # is the Color channel turned on? if color_ch==0: return texture=mat[c4d.MATERIAL_COLOR_SHADER] # is there anything in the Texture slot? if texture==None: return # is it a bitmap/movie? if texture.GetType()!=5833: return # render the bitmap to the Picture Viewer irs = c4d.modules.render.InitRenderStruct() if texture.InitRender(irs)==c4d.INITRENDERRESULT_OK: bitmap = texture.GetBitmap() texture.FreeRender() if bitmap is not None: c4d.bitmaps.ShowBitmap(bitmap)
Yes, I do get a "RuntimeError: illegal operation, invalid cross-thread call" error in the last line of code but, even so, I get an image in the Picture Viewer and it is ALWAYS the first frame of the movie.
How can I get the correctly calculated frame, according to the parameters set in the Animation tab inside the material channel?
