Voxel Pro 1.2 and Voxel 2.0

Development Programming & Scripting

Lately I have been having issues with my characters suddenly falling through my Voxel Terrains but then I notice they were not falling through but the Voxel Worlds would unspawn then when I moved back toward the last area I was on land the Voxel World respawned, and I could continue moving my character around. I tested with multiple maps, 3 different Video cards, fresh installs of UE5.5.4…

it was UE5.5.4 that has an issue (and possibly earlier versions as well.)

SO!

ok for now I have a work around.

it seems that it doesn’t matter whether I use Voxel 1.2 or 2.0 both versions have the same issue… its not the Voxel version or Voxel, its UE possibly only the newer versions of 5x. I didn’t have this issue in the past.

the Voxel map coordinates set the center to Vector 0, 0, 0

I noticed that UE5x and earlier all set the landscape in the Positive Quadrant. So, I repositioned my Voxel Maps fully into the Positive Quadrant X+ and Y+… and problemed solved (and as a bonus the Voxel system is responding faster now.)

I tried 3 video cards and Fresh install of UE5.5.4 both with VoxelPro 1.2 and with Voxel 2.0

i7-7700k 64GB Intel ARC A770 (Things are working.)

Guess UE has a bit of a problem with the Voxels in the Double Negative areas (X-, Y-)

the Zed axis didn’t seem to matter.

You know it has always irked me in the past that UE would position the landscape only in the Positive Quadrant … makes me wonder if they have a problem with the math in the negative Vectored Quadrants. Hmmm

UPDATE:

As of UE5.6 this issue seems to have disappeared.

There’s a problem with the sample using voxel. Could you please take a look and help me out? Thank you.

Try reducing the Voxel size from 100 to 20, Reduce voxel world from default to half its size. and see if it still locks up.

The voxel system handles the memory better for the landscape than the Landscape of UE but still does take memory. I had similar issues with my system until I added more Ram and changed to a bigger video card.

I was running CPU: i7-7700k, Mem: 32GB DDR4 2400MHz, GPU: AMD RX580 8GB, OS: Win10, MB: Asrock B260M Pro4. Now I am using CPU: i7-7700k, Mem: 64GB DDR4 2400MHz, GPU: intel ARC 770A 16GB, OS: Win11, MB: Asrock B260M Pro4. And I haven’t had any Lockups since I added the addition ram and changed the GPU.

Sure Onlyhan I can look what seems to be the problem?

first check your Virtual memory settings. using Task manager look at the GPU and see how much Dedicated and how much Virtual memory you have. Windows uses part of its virtual memory as a swap memory for the Video card.

When UE becomes unresponsive look at the task manager and see if either the CPU usage or the GPU usage is maxed. if either are, and I’m betting the CPU is, set your Virtual memory to minimum 2x your ram and max to 3x your ram.
