if i dont have textures for my milkshape model,jMe refuses to load model.(jMeException)
corrections needed to:
com.jme.scene.model.msascii.MilkshapeASCIIModel
::loadTexture(String file)
-check if file is null(or does it send ""?)
::parseMaterials(BufferedReader reader, int numberMaterials)
-when assigning check if texture is not null and assign after that
Can you provide a stack trace? Also, if you can provide the model you are testing with, that would be great.

i will upload model to my homepage tomorrow,i cant currently,looks like my internet provider doesnt allow connecting to ftp outside their network
but i guess only important lines are material lines in ascii file and they are
Materials: 1
"foomaterial"

i dont give texture filename because this model doesnt need any textures
and it's not checked on loader it just parses and passes it to texture readed but doesnt check if its null
Checked in a quick update to TextureManager that will fix the error in the stacktrace. Please try again and fwd any more stacktraces.

I’ll take care of this today. I’ve known about this for a bit now. Just never got around to resolving.
Ok, I have checked in TextureManager and MilkshapeASCII. These should handle non-existant textures better. If you are still having trouble, reply and perhaps send me your milkshape file.

model can be found at http://www.netikka.net/mika.pesu/model.txt
Hmm, that link seems to have an invalid milkshape file format. Specifically, it reports 120 triangles: but the 111th triangle is incomplete and the rest are missing. That is, the file ends with:
1 82 25 83 56 15 57 1
1 25 29 83 15 17 57 1
1 83 29

i’m not sure why this happens,looks like it gets corrupted if i send plain text files. new one is zipped
ok, found the issue and fixed it. Your model is loaded on my computer. Update cvs and try it out.
yep,it works now,thanks.
