Only 1/4 of a picture was rendered

I done multiple complex 4K rendering before this one, and that without any problem.

13400f/3060 12gb/32GB DDR5

Hi mate, It looks weird, Can you send the logs, files, and video to us for troubleshooting? support@d5techs.com

How to collect logs:
D5 Support Tool - Get Help / Tech Support - D5 RENDER FORUM

The video is rendered separately or using render queue? Please follow Bruce’s advice to send us the files and video for further troubleshooting; we are looking into this issue, thanks in advance!

Hi mate, we test the scene with 720,4k but cannot repro that situation. 720 is fine without any problem, 4k crashes many times during the process.

Rending only one 5min-clip has a high risk to lose all of them, Divide them into more clips(maybe the 20s each), and then combining them will lower the risk. Also, we will improve the D5 video function so the combining process can be done automatically in the future. sorry for the inconvenience.

Anyways, we will still try to repro the situation and find the problem.
