Expand Your World With Volumetric Effects
B站中文版
I was invited to do an episode of Inside Unreal about my volumetric techniques. Here’s the VOD. Pretty pleased with what I could came up in one week. The chat was super fun and nice. I had a blast!

Create nice and feasible volumetric cloud in Unreal Engine 4 | UE4之制作高端霸气的干冰体积雾
Summary
Making beautiful and feasible volumetric effects has been a trending topic for game development. Inspired by the Gears 5 tech talk and the good ol’ Guerrilla paper on cloudspaces, I decided to do my own take and created this fluffy dry ice fog using Volumetric Fog feature that comes with UE4.

This is done purely within Volumetric Fog and Volume Material systems, thus requires no low-level coding and supports various lighting feature within UE4.

Continue readingPerforce backup with rsync
First thing to know, I don’t really want to backup the entire perforce database since it’s huge and requires a lot of extra steps. I’m only backing up the latest version in case a doom fire happens to my apartment.
The scheduled backup is run on my p4 server A, in order to run a scheduled backup plan to push my newest project version to server B.
Create client(aka workspace) for the server A itself.
p4 -d `pwd` client -t Vuth_Auri -o Auri_Backup | p4 client -i p4 client Auri_Backup
Then run a script in crontab.
51 * * * * bash /home/vuth/__backup/runBackup.sh
$cat runBackup.sh
p4 sync rsync -rtz -e "ssh -p 1111 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /home/vuth/.ssh/id_rsa_somekey" /home/vuth/__backup/p4 vuth@123.123.123.123:/home/vuth/p4
First line get the latest version of your project to the workspace.
Second line runs rsync over a ssh connection to your remote server B.
And that’s it. Notice that this is incremental. You can add –delete to the rsync command to remove garbage from remote server B. I left it for extra safety.
