How to import a model dazstudio (obj) in Sketchup?

I hope that chap intends to go into battle with a bit more armour.

Wow, this looks like a horror movie. After teleportation, your body parts end up messed up!
It is rather like that ! The geometry arrives reasonably OK - although in the initial versions the poor guy's skin was on 'inside-out' [yeuk!], but no matter what tweaking is done he ends up with either giant eyeballs on top of his head, lips on his forearm, hair where it shouldn't be etc...
The "Hiesenberg Uncertainty Principle" at it's most extreme [the very reason Star Trek Transporters, the Fly teleporter etc won't work safely...]

I can tell you the problem I think

Poser/Daz studio OBJ's tend to use stacked UV maps to maximize space on the map. also it's not uncommon for a texture map to be 4096x4096 in size for the skin etc, tho many will goto 8192 these days

If I'm right, the body has a huge Head UV stacked on top of it....

I've seen figures have a lot of issues due to the UVs thanks to this method...

So if I understand Dazstudio and sketchup are not compatible with export | import.

Dazstudio to Sketchup :
mapping = not good
Polygon = OK

Sketchup to Dazstudio:
mapping = OK
Polygon = OK

We found that the teleportation has a significant impact on skin.
Use teleportation with moderation!

actually not quite

you can export from DS to SU with no issues on the mapping if the UVmaps are not stacked (overlappying)

if the export has single layer maps, it should work ok. that counts out the current generation of Daz figures tho...

Ok I’m doing a test.
Here are my Dazstudio presets:

OBJExportOption

To: Custom

Scale: 1%

Axis Conversion
(X)Invert Positive direction = not check
(Z)Invert Positive direction = not check
(Y)Invert Positive direction = not check

-Ignore invisible nodes = not checked
-Use bone welds = not checked
-Remove Unused Vertices = not checked
-Write UV coordinate = check
-Write-Normals = not checked
-Write object-statements = not checked

-Write Groups = checked
-Use existing groups = checked
-Use nod name = not checked
-Use surface name = not checked
-use figure name = not checked

Write-surfaces = checked
-Write Material Library = checked
-No-maps = not checked
-Collect maps = checked
convert maps (for bryce)= not checked

[TIG]

Why not Scale 100% ?
Try it with Write-Normals checked ?

Some of the second OBJ's texture image seem to be missing - like '2_SkinHead.jpg' that is required in the MTL file, but is not in the 'Maps' folder [although they would really need to be in the MTL file's own folder anyway...] - therefore there are no face/body textures ?

This probably won't fix issues, but it isn't helping !

Hello ThaiI, am not able to successfully import an obj Michael 4 (model of dazstudio) in Sketchup.

Have you managed to import a sketchup model with texture in?

If yes, can you list me the exact settings?

I am a beginner with Daz and I can not find how to make sure if the mapping UVmaps are not stacked (overlappying).

Thank you in advance and sorry for my bad english ...
