Is there any way to make glow with Extra version of Game studio? I need some part of my models to Glow. Like some lines on the doors for example.

unfortunately shaders are only available with Commercial+


My really lame idea for you:
you could save your original model (example) "gun.mdl" as "gun_glow.mdl" - and make sure that gun_glow is a bit larger of scale, and invert the faces, to give somewhat of an outline. then call it in game through programming.

Ok, but that will look really bad and cheap Thank you any way.

or you could use sprites for let the model look like its glowing

...and use the ZNEAR for the sprite...
