Title: MD5 error/textures not loading
Post by: TedBudstorm on May 06, 2015, 11:03:46 PM
I was just learning how to use Bonzai Engine and I am getting this error when trying to use MD5 models and animations, and some textures are not loading.

Console output:

There seem to be some problem with the cpu skining code with your model, which seem to be used because the shader is not yet loaded.
The best would be to send us the model so we can fix it (via the forum or our contact email). In the meantime, and as a workaround, you can request a shader only context to ensure the cpu skinning code is not used. To do that, you can use DisplayCapabilities.setGLApiVersion (http://bonzaiengine.com/javadoc/com/bonzaiengine/opengl/DisplayCapabilities.html#setGLApiVersion-int-) with for example 30.

About the texture not found, can you locate them ?
Where are they related to the model ?

The textures are located in the same location as the MD5 model

Like

>res/models/md5/bob_lamp_update.md5mesh
>res/models/md5/bob_lamp_update.md5anim
>res/models/md5/bob_body.tga

Most of the texture not found are the diffuse. MD5 format don't explictly reference the texture files, by default the engine use the following pattern:

So for bob_body.tga, you should rename it to bob_body_d.tga
If you don't wish to rename any file, there's some way to plug some callback when a texture is not found (ex: bob_body.tga) and try to open another one (ex: bob_body_d.tga) by code.

I'll give a look to your model, when I can.

Okay, I fixed all of the file names, and now I get this

I think the "Implicit version number 110" error was fixed in the 1.3.3 dev builds.

Yeah, that seems to have worked, thanks. :)
