Hi!

can you put your files here so that I can have a look to them? If you don't want to put them here you can send them by email at contact@arnaudguyon.fr

thanks!

I successfully displayed it :)

• first put your jpg file in a "drawable-nodpi" folder instead of "drawable" so that it will be loaded at its exact size (I will update the documentation with that).

• when you create the model, don't forget to put the correct name for the material (01_-_Default_CMRO_TEX.TGA)

WavefrontModel model = new WavefrontModel.Builder(context, R.raw.camaro_obj)
                .addTexture("01_-_Default_CMRO_TEX.TGA", mSpaceCruiserTexture)
                .create();

• finally scale and place the object at the correct position

mObject3D.setScale(1f, 1f, 1f);
mObject3D.setPos(0, 0, -6);

with all this you should be able to see your car on screen.

It remains 1 issue, the mapping does not seem to be correct. Note that the .mtl file is not used, it is not planned to use it so far. Maybe there are some important values there for mapping (like an offset or something).

I don't have enough time today to investigate more.

tell me if you can see the car with those changes, and if there is still mapping issue.

Hi,

I have found the issue. Vertical mapping is inverted in smartGL : if you try doing a vertical mirror on your jpeg then it works with smartGL. I'll fix that as soon as I have time.

Hello Lai,

I've made a fix in release 1.1.3. Could you please use it and tell me if this is ok for you?

And are you ok if I use your car as a sample for my library ?

thanks!

Arnaud.

I assume the bug is fixed (tested on my side), so I'm closing the issue.
