FluidImporter free .obj importer Beta 1.0.5 Updated
-
Hi fluid!
Wonderful tool, your obj importer!..still, I seldom find some troubles in importing some obj files: most od the times SU reads the textures and UV mapping very well, but sometimes it happens that only ONE material is read from the source obj file, and it is applied to the whole geometry (note: all the faces are correctly UV mapped with the texture of the only material imported).
How come this? Can I fix it?
Thank you a lot!

The OBJ importer tool is in need of at least one last tweak... it isn't reading the materials 'alpha' from the MTL file. For example...
newmtl Translucent_Glass_Gray
Ka 0.000000 0.000000 0.000000
Kd 0.500000 0.500000 0.500000
Ks 0.000000 0.000000 0.000000
d 0.600000The d value is used as this material's transparency 'alpha' thus -
material.alpha=d -
I use Tig's .OBJ importer... is there something different about this one? does it allow me to import a glass of beer? cuz I could use one.

This new 'compiled' OBJimporter WILL be better than mine - IF he fixes the transparent material issue...
It's faster... -
Hi pibuz, can you provide the file that causes problems?
-
Just released 1.0.3, should have transparency working properly.
-
Super !
-
Thanks!!!

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:
http://www.xfrog.com/2011/01/130-free-xfrogplants-now-available/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..
-
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... -
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..

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!
Theusemtl lefetc before each set of face definitionsf 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?

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