I have made new blaster pistol model. I have created my10.mdl; my10.mdx; my10.txi; my10.tga; my10.uti. Models looks working. Textures too. I have based it on standard blaster pistol (as I remember g_w_blstrpstl001). I have changed it to my new model rename in the same maner. I think problem is in model variation. How to set right model variation?

unless you want to create a new baseitem, just use the games default model names. So for your blaster pistol you would name the model files w_BlstrPstl_xxx.mdl & w_BlstrPstl_xxx.mdx, xxx being the model variation.

By naming the model that you can use the baseitem 12 in the uti and in the model variation node(of the uti) use the number you named your model.

The texture and uti can be named what ever you like as long as the file names are unique.

Ok. Thank you T7nowhere for helping me with my problem. It is working now! And thanks to SReedy85 for trying to help.
