Applying Texture using Collada model

Troubleshooting General Help
1

Hi All,



I have created a small collada model and have it showing up in jME… I want to now apply a texture to the surfaces in jME (not in Blender which I used to create the model). I have tried many things and the texture never shows up. I am new to jME, so this could be a simple problem.



Here is my code (mostly from examples). Thanks for any help! I assume it's possible, but don't seem to know how?!?



Thanks for a great product…I think it'll be very fun to use!

The code looks ok to me, do you see no texture (if so what color has the model?) at all or the default jme texture?

I see no texture, just grey faces. It may be something I need to do with the collada model (the model is > 20000 chars though so I couldn't attach).



I'll do it in two posts… here is half of the collada file I'm using:

i don't really know about modeling sorry :)  are there texture coordinates in the collada file (didn't see any, but i don't know what to look for anyway)?

6

No, I don't think so. I guess one thing I don't understand in jME is texture coordinates. I've read the docs that there are a range from [0 1], but don't quite understand what that represents.



If you know that, let me know and that may help me debug from there.



Thanks so much for your help! I do appreciate it!  :smiley:

Try researching UV Texture mapping. I found this blog post which will explain the concepts to you, it even has a 3D applet running to show how it looks. Neat! http://rozengain.com/?postid=45







Edit: Also added this link to the wiki @ http://www.jmonkeyengine.com/wiki/doku.php?id=links

Yep, i guess you need to create the uv mapping in your 3d modeling app.

Then later when you apply the TextureState to your model in jME, the Textures will be applied correctly (hopefully :))

Hi, everyone.  I have encountered the same problem.  I'm using 3d max + ColladaMax plugin to generate the simple textured model.  But the texture just doesn't show up in JME.  Has anyone sucessed to get the collada  model texture from 3d max or Maya work in JME?  Hopefully the problem can be solve soon.

Hi,



Actually, I think based on the previous emails I did solve my problem. The key was UV mapping. When I added in a UV texture map in Blender, then saved the model file.



I then loaded the model using jME. From there, when I use the code I posted to add my own texture to the model, the new texture showed up. One oddness is that if I do not add my own texture, the Collada texture did not show up (just shows up as gray). However, exporting an Obj file instead does show the initial texture from Blender also.



The key (as the previous posters told me) was UV mapping. Thanks to all for the help!



Let me know if you need more help.

Programmically texturing the model after it's loaded in JME may solve the problem.  But most frequently we just want to keep the texture originally created in the collada model.  I just can't get it work. ://

It's strange that in the sample code named TestColladaLoading with JME  the models works fine with the texture.

Really quite strange… :?

12

haha, problem finally sovled! :smiley:

The reason of the problem is the colllada importer in jME currently only supports lambert and phong shading.  So by applying textures using these two methods in modeing applications,  the texture is finally displayed in jME.

it would be good to collect those collada importer limitation, maybe in a wiki page or in the jme 2 issue tracker so that the a developer or the community can implement or fix missing features.
