Hey I need help getting started I have no money to buy the full version to make it easier on myself but does anyone have money to throw around. But lets get to the point I'm trying to start but no model making software lets me make and models with the file type .mdl . This is a serious problem for me and my friend we have tried blender and it makes .blndrmdl files or something like that. I have just tried renaming lets say ex: cube.blndrmdl renaming it to cube.mdl it should work somewhat but it doesn't it says invalid .mdl file retry?

My question is. Is there a model maker that supports only .mdl not made for old source engine games(ex:steam games made by valve) that I can't use.

Well If anyone has some suggestions Please help me I really need it.
