Viewport freezes

All Viewport’s functions just freezes indefinitely (all grey out) after I hide some objects . I could still select objects and move them around though. Had to restart the project without saving :frowning:

Hi caominh,
Sorry to hear that you ran into this problem. From your description, I think it is due to that the CPU was still calculating during that time. Besides, how about the RAM usage?

Although it is not saved, I think the Auto-save function is turned on by default, so you may check the version history to see whether you can recover the file from that.

What’s more, please let us know the hardware information, or you could use the support tool to get a log file for us, with which we can narrow down the issue cause. D5 Support Tool - Get Help / Tech Support - D5 RENDER FORUM
