Here you go this should work i tried it on a lot of meshes and they all seemed to work. I am not sure what you will learn from this they are very low polly and look like collision meshes.

wow, great work chrrox! Thank you for taking the time to decode this format for me.
I know it will be very educational and hopfully useful for others as well.

I don't have max unfortunately would it be possible to rewrite an importer for blender?
Thanks you again, I appreciate your help very much! and sorry for this other small request.

[chrrox]

The format was fairly basic. I do not know how to code for blender sorry ma-bee some can help you there.

[Shinokaze]

hello again chrrox, Ive gone ahead and downloaded the latest trial version of max after playing around with it for a few minutes I'm able to open and run a script but after selecting the .c3 file I wish to open it comes back with these error message.

Code: Select all

--Runtime error; buildTVFaces; mesh has no texture verticels - $Ditable_Mesh:Objec001 @ [0.000000,0.000000,.000000]

Code: Select all

--No'+' fuction for underfinded

Is it max 2011? if so ill have to test my script with it max 2011 can be very picky with spaces and other things.
also make sure the file you want to import contains a mesh alot of the files you posted were just animations.

Shinokaze,

The posted script does not like all .c3 files.


I added the .c3 loader module to my program and I released the 3D Object Converter 4.433 update package now.
http://web.t-online.hu/karpo

Please install the v4.40 or use the v4.40 portable version.
After that you must upgrade to the latest version (v4.433) using the Help/Check for updates... function.
