Black texture after fusing scans

Product Name: SLS-3 HD
Operating System: Microsoft Windows 7 (64-bit)

Hello,

 

I'm currently using the HP 3D Scan Pro 5 software with the David SLS-3 HD hardware. Everything works fine until I want to fuse the meshes.

 

When I only select few scans (4-5) the fusion process is successful. If I select more or even all of my scans, the fusion either causes the software to crash or produces a valid mesh, but without texture. The whole object is black. The fused object's surface looks fine if I hide the texture.

Re: Black texture after fusing scans

I am not sure why the software is crashing. Possible problem could be large number of scans and not enough resources. If your texture is all black, you can try to export fused object in .OBJ format and texture will be in .PNG format. Change the resolution of .PNG texture file into 2048 x 2048 or 4096 x 4096 if you need bigger resolution and import your object into HP 3D Scanning software again. It should be shown correctly.

Re: Black texture after fusing scans

Hello, I had problems of partially black textures with DAVID 3 and 4, and they were due to the AMD graphic card. No problem with Nvidia. You can also try to run the x86 version of David instead of the x64, i.e. the version for 32 bit operating systems.

I do have the problem of having completely black textures when I open a model that I took a year ago with DAVID 3 into a more updated version, but it is only a david problem. If you open the model in meshmixer, or meshlab, or open3dmod etc, the textures are fine Smiley Happy

Hope that helps a little...

Hi Vito,

 

long time no see Smiley Happy Resizing textures would also be temporary workaround for you.

Re: Black texture after fusing scans

Follow up: David 4 still crashes for me when I try to fuse scans, especially a lot, but there are some unselected scans in the list. Maybe this can help?

Re: Black texture after fusing scans

If you select all scans for fusion there will be no crash?

Re: Black texture after fusing scans

Have you started separate topic about this? If not please do so. We are going off topic.

Re: Black texture after fusing scans

[ Edited ]

Thanks a lot for your help. I will try to resize the textures and to open the model in another software next week, when I have access to the computer concerned. Perhaps this workaround helps. I will let you know about it.

 

I encoutered crashs of Scan Pro also only when selecting only a subset of my scans. When all scans were selected, I didn't get any crashs.

Re: Black texture after fusing scans

We will try to recreate this problem, as a temporary workaround you can save one copy of your project for archive (with all scans) and other one for fusion (contains only scans that will be fused).
