Nej, your question isn't stupid ^^
Meshes are like objects to make it simpler to understand or basically something that defines model, a collection of vertices and edges. c:
I'm sure you can make meshes in blender, but there may be some other method out there that might be easier.
Hope I didn't confuse ya ^^
P.S this seems like it would go in the help thread c;
You're welcome ^^
And the help thread is for any question that deals with the game or even on the forum and not just in-game. Like the question you asked is like...for maps/map making, etc and that deals with the game c:
This board is more of a discussion, thoughts and all that good stuff that deals with the game / forums if that makes sense c:
