General / fbx texture numbering issue

« on: October 31, 2022, 05:24:01 PM »

Hi,

i have an issue when i export a model as fbx.

Metashape is naming the textures as:

modelname.png
modelname1.png
modelname2.png
modelname3.png

instead of
modelname1.png
modelname2.png
modelname3.png
modelname4.png

So the first texture file ins't loaded by my other softwares. I have tried with "fbx review" from autodesk and with Unreal.

Is there any way to fix this ?

General / Please modify the "use existing depth maps" feature

« on: September 22, 2022, 12:49:41 PM »

Hi,

when making a mesh there is the option to use existing depth maps.

But if you change the region, when enabling this option, it will only use existing depth maps.

It should use those depth maps but process the missing ones needed for the new region.

Could you make this possible, otherwise we have to process all depths map again :-(

General / Need help to use Quick_layout script with laser scans

« on: September 22, 2022, 12:45:42 PM »

Hi,

i'm trying to import laser scans images and point cloud.

I know that i have to use quick_layout script but i must be missing something.

I import the laser scans (images), use script, but when i align cameras they loose their position.

and when i import the point cloud from the scan it's not aligned.

Could you please repeat the exact order to do things for this ?

do i have to check the images in ref pane before/after script ?

for alignement should i enable "generic preselection" ?
should i enable referecence preselection with source ?

thanks !

General / Bad texture issue

« on: March 28, 2022, 03:09:03 PM »

Hi,

i have issues with the texture génération. Very often some parts of my model have bad blurry texture.

Here for exemple:

Metashape model (ultra high setting, 32x4k texture) (don't forget to select hd for textures in the tool box)

Mac Photocatch model in raw settings:

Look around the mouth for example.

General / How to find the optimal texture resolution ?

« on: January 26, 2022, 03:02:04 PM »

I'm using 8k textures.

How can i find how many of them i need for a model to get the best result ?

using too few is obviously not giving a good result.

but i have noticed that too many gives a worse result too so it's important to have a way to find the right number.

General / We really need help to fix the Cesium tiled format output

« on: January 20, 2022, 06:25:25 PM »

There is definitively something wrong with the cesium tiled output.

There have been several messages on the forum about that so i'm not the only one having issues.

Could please have a look, this i a very important feature to be able to use our very large models. 

Here is a tiled model generated by metashape:

Using cesiumjs with inspector tools:
https://www.gigascope.net/vr/tilesfrommetashape/

Using my aframe vr viewer:
https://www.gigascope.net/vr/tilesfrommetashapeaframe/

link to download the tiles:
(https://data2.gigascope.net/3d/tilesfrommetashape/street0.zip)

And the tiled model from cesium when i upload the obj to cesium:

Using cesiumjs with inspector tools:
https://www.gigascope.net/vr/tilesfromcesium/

Using my aframe vr viewer:
https://www.gigascope.net/vr/tilesfromcesiumaframe/

As you can see something is broken in the metashape output, you can use the inspector to see that the Bounding and Content volumes are wrong.
