How to add more texture maps to obj
« on: June 04, 2022, 01:24:53 pm »
At present, I only know how to add 1 texture map to an object
But the exported obj has many texture maps

I believe the general logic should be:
- Load textures with full names
- Load model file
- Load MTL file
- Load 3D object using model and MTL files

If used properly then Object3D#setTexture(...) is not necessary
The model loader will find the texture names that are specified in the MTL file. But these names should be properly set in the texture manager.

Instead of this:
tm.addTexture("_Vegetation_Blur7_1",_Vegetation_Blur7_1);

Try one of these:
tm.addTexture("changjing2/_Vegetation_Blur7_1.jpg",_Vegetation_Blur7_1);

Or:
tm.addTexture("changjing2/_Vegetation_Blur7_1",_Vegetation_Blur7_1);

Hello, aeroshark333

Thank you for your help, but I tried it. It didn't solve the problem

I found that it can only recognize one texture map, which is the first one in the MTL file

It should work that way. Have a look at the log output when loading the file. You should get log messages if a texture name can't be found and you should be able to see what exactly these names are.

I am a beginner. I don't know why I failed. Here is the log

That looks a bit strange....I expected some texture names to appear in the log. Can you upload the file so that I can have a look at it (next week...)?

Are these materials really used in the obj file? Maybe the export went wrong?

I'm sorry I didn't reply in time, because we are in different time zones, so my English level is also very low

At first, I planned to upload the attachment, but the file size exceeded 64KB

Are these materials really used in the obj file? Maybe the export went wrong?

Yes, I can find some keywords about texture in the obj file

Can't you upload it to some file host? Or just mail a zipped version to info@jpct.net

I had brief try on loading (but not rendering) the object and I can't see anything wrong with it. This is an excerpt  from the log output:

2022-06-07 16:56:12.148 6204-6234/com.example.androidtestcase I/jPCT-AE: Processing new material Groundcover_RiverRock_4inch!

Prior to loading the model, I assigned two textures to the manager:

Code: [Select]
TextureManager.getInstance().addTexture("02/Carpet_Loop_Pattern.jpg", texture);
TextureManager.getInstance().addTexture("02/_Wood__Floor_2.jpg", texture2);

Note that these textures don't show up in the log, only the ones that have no matching names in the TextureManager do. As all working as expected.

I'm not sure, what your actual issue is...you loaded the textures and the model but the textures don't show on the model? If that's the case, maybe you can post a screen shot of how the model looks instead?

Oh, and please wrap larger chunks of text or code into code-Tags (the # in the forum's editor). I did that for your former posts.

I loaded textures and models, but only one texture can be displayed on the model
