OBJ imports with no textures from max and uanble to dae format

bhaskarsjsj

Hello

I have created a 3ds max glass building with textures, and exported it as obj file with mtl and texture in the same citiengine workspace folder / models folder, but when imported into Citi engine it does not show any textures,

Is there anyway of applying manually.

I have followed all your procedures but still a failure.How Can I Create a Scene with .OBJ Texture?

Hi!

Have you tried opening the .mtl and checking the path name to the textures for each model component?

It should look similar to this....

newmtl component

Ka 0.000000 0.000000 0.000000

Kd 0.400000 0.392157 0.368627

Ks 0.330000 0.330000 0.330000

map_Kd YourAssets/YourTexture.jpg #This should be the path to your texture

Good luck!

Also check that the material name has no spaces:

like Micah said:

newmtl component

not like this:

new mtl component

I believe space in material name will produce that error you have.

I have tried everything you have mentioned but nothing is happening

can you be more specific about this ---YourAssets/YourTexture.jpg #This should be the path to your texture

this is what mtl I am getting after exporting to obj in 3dsmax 2014, all the texture and obj and mtl is in the model folder of citiengine workspace\

can you please make the problem here please.

The file appears to be formatted correctly so I am not sure how to fix this. However, I have done a couple of things on my obj files in the past that seem to have worked. Try rearranging the file in the following formats and see if it works...

Try this one first.....

newmtl Arch41_057_mat_1
Ns 0.0000
Ni 1.5000
d 1.0000
Tr 0.0000
Tf 1.0000 1.0000 1.0000

newmtl 13___Default
Ns 10.0000
Ni 1.5000
d 0.5000
Tr 0.5000
Tf 0.5000 0.5000 0.5000

newmtl 13___Default

Ke 0.0000 0.0000 0.0000
map_Ka HighRiseGlass0055_2_S.jpg
map_Kd HighRiseGlass0055_2_S.jpg

Try this one next (remove the illum entirely)....

newmtl Arch41_057_mat_1
Ka 1.0000 0.8784 0.0667
Kd 1.0000 0.8784 0.0667

Ke 0.0000 0.0000 0.0000
map_Ka HighRiseGlass0055_2_S.jpg
map_Kd HighRiseGlass0055_2_S.jpg

Lastly, try putting ONLY TEXTURES in a separate folder within your "Models" folder (For example : models/RandomFolder/HighRiseGlass0055_2_S.jpg) and try this format...

newmtl Arch41_057_mat_1

Ka 1.0000 0.8784 0.0667

Kd 1.0000 0.8784 0.0667

If none of these work, zip up the textures, obj, and mtl and attach it in a comment and I will see if I can get it to work on my end if you like.

Another thing you might try is this....look within the software you made the model...and find the option to "Export two-sided faces" and DISABLE it. I have had this problem in the past as well.

Good luck, I know this is frustrating from experience; especially when you spend a lot of time building a model and it will not export.

MicahTaylor

Also, dont forget to refresh the "models" folder and workspace every now and then.

bhaskarsjsj

Thank you Micah Taylor

Nothing is working, there should a much easier way of importing 3d models like fbx which does have much complication like obj files.

can I assign the materials manually in citiengine for the model.

Is there anyway for it.

I have 3xported it in 3ds max 2014 , where can I find "Export two-sided faces" in 3s max.

thank you once again

Hi there,

The Tr in the .mtl files is transparently, so when CE are receiving Tr 0, it means that this is fully transparent, and not visible. So it’s correct that you need to reverse the transparency 0 = 1, the rest I usually leave as they are, but I think the right way to do it would be 0.55 = 0.45. I don’t know why it is reversing it like that, maybe there is a fix.

You will have to check if you are assigning the materials in 3DS as standard materials, if not you are not able to see them outside an autodesk product, since .obj not are supporting autodesk materials. I couple of test I ran with FBX export from an Autodesk product, shown that even if you are exporting as FBX, other applications will not recognize Autodesk materials (the couple I’ve tested anyway)

So you will have to go from something like this:

To this:

The you will be able to see your materials i CE

This seems stupid, but I don’t think it’s CE to blame, but more like the autodesk materials, not being able to show outside of autodesk. But again they work great inside Autodesk

bhaskarsjsj

Hello Kenneth

thanks for your advice, I can see the materials but is looks very transparent

how to change it to normal dark material

KennethLindhardt

So your materials are visible?

The way I see you material the (if o remember it correctly Arch41_057_mat_1 material is fully transperent. Change 0.0000 to 1.0000 after Tr the next material is half transperent since its 0.5000 after Tr, change that to 1.0000 play around with those values, if I should remember it the opposite way .

Remember to refresh the folders, and regenerate the model. If you can see materials you are 90 procent of the way.

KennethLindhardt

By the way feel free to make the model folder available online, if you don't resolve this, maybe I can have a look tomorrow.

bhaskarsjsj

Thanks Kenneth once again

but one more thing when the models are imported the face get split in to multiple faces/ polygons.

how to resolve this, there are two many faces and the maps are assigned to multiple individual faces/ polygons

if there is a curved surface and it get split into multiple polygons,

and how do I make the model folder available online shall I zip the folder and attach it here.

and how do I attach it here.
