Thanks!!!

Hi pibuz, can you provide the file that causes problems?

Hi Fluid! Thanks for your reply! I'm really looking forward to slve this issue, so I can start building a good set of outdoor vegetation

You can pick a random tree from this link:

They all show the problem when I try to import the obj file. Note that all textures are in the same folder as the obj model, so I guess there is no path conflict or anything..

TIG

The texture image files need to be in the same relationship to the OBJ file, as set in the MTL file.
Open the MTL file in Notepad[++] and read it...
You will find that Xfrog OBJ texture image files usually stay in the same folder with the OBJ, as there is not a subfolder specified by the MTL file.
If an MTL file needs a subfolder for the texture image files' paths then if it doesn't exist you simply make a new folder to match, next to the OBJ file, and move the texture image files into it...

pibuz

Oh thank you TIG, I'll check that!

EDIT: just checked and in fact no subfolder seems to be required.
BTW, after the import, the material given to the branches is applied to the leaves too...

I'm attaching the mlt file to make sure I'm not reading it wrong..

These are relatively large objects with complex texturing and take a while to load...
Over 53 million lines of code in the largest OBJ in that zip !!!
They are so 'heavy' that one or two can kill you model - avoid shadows etc !!

I see what you mean as typically only 1 texture comes in - the first one !
When the OBJ and MTL says there are perhaps 7 in the original !!
The MTL file correctly specifies the materials, the image files are there and the OBJ correctly assigns materials to faces half of the face son my import are wrongly oriented - so you need to run one of my tools to add the material to both faces, smooth edges etc so it looks right!!!! ....

My old clunky Ruby based importer does work... but takes [almost] forever to process the OBJ file !
and then it's 40Mb and half the faces are wrong so I have to fix those with another tool and then add matching back materials and hide edges etc...

Fluid... back to work ! The material importing is broken!
The usemtl lef etc before each set of face definitions f 1/2/3/... needs to be read in used AND the materials made from the MTL specs...

I'm getting crashes when I try to import an .obj file I got. (120MB)
I've tried different options - triangulate on/off, material on/off - but it bugsplats every time. Memory usage of Sketchup.exe doesn't exceed 300MB.

Any ideas?

Wow, that is extremely fast! Thank-you

Best,
Jason.

Thomthom, I've never tried a file that big. How many polygons is it?

Did you also see this? http://forums.sketchucation.com/viewtopic.php?p=320223#p320223
The materials using textures [after #1] aren't being made from the MTL or then applied to the right faces

fluid

TIG, yes, I did. Please be patient, it'll be fixed soon. I'm just working on this on my spare time

TIG

No problem
Just checking...

I do not know - it's a file we got from different office.
Do you got dropbox? I could drop you the file if you want to have a look..?

pibuz

Thank you fluid for the effort you're putting into this!
We're all grateful to you, you're providing an excellent tool.

..so are you all, from Thom, to TIG, to everyone who contribute to make SketchUp a more powerful software!

fluid

Thomthom,, I just installed Dropbox, how am I gonna share a folder with you?

fluid

Just released 1.0.4, it should fix the face/material issue.

TIG

Thanks again!
This update does indeed seem to address the textured materials import issue

pibuz

Works like a charm!
Thanks TIG for the support and a GIANT thank you to fluid for this excellent tool!
