My test environment:
Cinema 4D version: CINEMA 4D R19.068
Renderer: Octane renderer 3.07 R2
This is my code:
# -*- coding: UTF-8 -*-
import c4d
from time import sleep
# Save path
save_path = "D:\\temp" # It's my dir for test. Change it if you dont want to save your bmp at here.
class RenderThread(c4d.threading.C4DThread):
global save_path
# Override
def __init__(self, doc, rd, bmp):
self.break_flag = False
self.doc = doc
self.rd = rd

def Main(self):
self.res = c4d.documents.RenderDocument(
self.doc,
self.rd,
self.bmp,
c4d.RENDERFLAGS_EXTERNAL
)
# Just a test for distinguish the result file is saved by which thread.
# If i get this file, it indicates that the render thread has run completed.
if self.res == c4d.RENDERRESULT_OK:
self.bmp.Save(
"{}\\RenderThread_SaveResult.jpg".format(save_path),
c4d.FILTER_JPG

th.Start()
count = 0 # When "count" equals 10, end render thread.
while True:
print "Current count ->", count
# Show bmp to picture viewer
c4d.CallCommand(430000740, 430000740) # Remove All Images --> Clear history, just show current bmp

if th.res == c4d.RENDERRESULT_OK:

# Test of break render thread

# If i get this file, it indicates that the render thread has break.
th.bmp.Save(

break

sleep(1)
if __name__ == "__main__":
c4d.CallCommand(13957) # Clear Console
main()
There has two questions:
- In fact, render thread is not break... this is my c4d console log:
After "End()" has executed, render thread is still running...
Emmmm... how to really end render thread ?
- I got a image after "End()", but the image has a state bar at bottom...
So, can I get the image without state bar when I break render thread ?
This is the image:
Finally, I will got two images, because render thread doesn't break:
