Hi, I had the same issue but solved it.
Make sure to enable "HOUDINI_VDB_FORCE_STREAM_SAVE" variable in your .env file.

Hi, I had the same issue with my Linux Mint machine, but I solved it yesterday!


✅ Issue

Houdini's Render Gallery uses SQLite to store data. When saving to a NAS (Network Attached Storage), users may encounter errors such as:

・ database is locked (5)

・ Permission Denied

This happens because NAS file locking mechanisms interfere with SQLite’s required locks.


✅ Causes

1. CIFS (SMB) mounts do not support SQLite’s byte-range locking by default.

2. Houdini’s Render Gallery relies on SQLite, which cannot function properly if locks cannot be acquired.


✅ Solutions: Add nobrl Option for CIFS (SMB) Mounts

If using CIFS (SMB) to mount the NAS, follow these steps:

1. Unmount the existing NAS mount:

sudo umount /mnt/NAS

2. Remount it with the nobrl option:

sudo mount -t cifs //NAS_IP/your_share /mnt/NAS \
-o username=your_user,password=your_password,uid=1000,gid=1000,vers=3.0,nobrl

3. To make this change permanent, edit /etc/fstab:

sudo nano /etc/fstab

4. Add the following line:

//NAS_IP/your_share /mnt/NAS cifs username=your_user,password=your_password,uid=1000,gid=1000,vers=3.0,nobrl 0 0

Apply the changes:

sudo mount -a


If you use SMB to mount NAS, it might help.

Hi,

I'm encountering an issue with Arnold in Solaris.
As you can see in the attached picture, the curvature node doesn't work properly when using CPU mode.

Only Curvature_Convex returns nothing.

Has anyone else experienced similar behavior?
I have attached the .hiplc file link for the reference.

If someone could take a look at it, I would greatly appreciate it.



Thanks,
Kensho
