Solokiller's Half-Life Model Viewer
(October 14, 2017)
Solokiller's Half-Life Model Viewer is a GoldSrc model viewer written from the ground up for improved performance, memory usage, and cross-platform portability when compared to Jed's Half-Life Model Viewer. This makes it much more stable and efficient, and it comes with a host of other new features and improvements. You can load a model using the "File" menu or by dragging it into the viewer.
Solokiller's Half-Life Model Viewer features Steampipe support, per-axis mirroring to better represent how Counter-Strike viewmodels look in-game, in-depth viewing of model bones and attachments through new panels in the UI, more accurate rendering of chrome textures, backface culling, surface normal viewing, and smoother rendering of animations, among others.
As of v2.2, you'll need the Microsoft VS 2017 x86 Redistributable to run the program.
