Models: 3D Artist's corner
Welcome to the 3D Artist's corner. Here you can learn about creating 3D models for qfusion.
This page is still very much work in progress, and there seems to be little actual information on creating new 3D models and visual effects for qfusion
- The model formats more often used in qfusion development are: IQM (Inter-Quake Model Format), MD3 (for animated meshes) and LWO and ASE (for static meshes).
The preferred format for qfusion is IQM A format that is also used by some other open-source games like Xonotic and Cube2 based games. So you might be able to use some documentation from these games too. Here is a tutorial how to get a .iqm playermodel into Xonotic which should work very similarly in qfusion.
qfusion doesn't use specific bone names for things, but "tags" bones as tagmasks like this:
tagmask "Bip01 R Hand" "tag_weapon" -2 0 0 // numbers mean offset forward, right and up
You can perfectly call "Bip01 R Hand" absolutely anything as long as you show it in the animation.cfg file.
Playermodel textures usually are 512 x 512 or 1024x1024 etc. and there are usually 3 textures on each model, head, torso, and legs. There are also diffuse, norm, gloss/specmap and colorpass/mask. A colorpass is a texture overlayed onto the model that tells what parts will be colors when you choose your team colors and player colors. Colorpasses have alpha channels, and everything painted white gets full color, while grey to black are less and less colorful.
For example: *padpork_head.tga *padpork_head_colorpass_fb.tga *padpork_head_norm.tga and:
- padpork_legs.tga
- padpork_legs_colorpass.tga
- padpork_legs_colorpass_fb.tga
- padpork_legs_norm.tga
Padpork doesn't have a colorpass texture on his head because his head stays pink when not fullbright (fb).
Note that many textures in the game have been converted to .ktx a special OpenGL compressed texture format similar to .dds. The engine will look first for these and if none are found will fall back on uncompressed .tga.
Animations are 1 big animation. Frames are specified for each animation from a text file (animation.cfg). A partially outdated (from before .iqm was used) file definition can be found here.
There is a root bone from where the upper animation is played. The code works works basically like this:
- It gets the bones for the main animation (run, walk, etc).
- It gets the bones for the upper animation (shoot, pain, etc).
- Mixes them in one new bunch of bones picking depending on the root bone.
- (it could add here another frames to be blended for animation transitions, but this step wasn't really needed here)
- Add special manipulations (rotate spine and head according to looking direction)
- Mount the skeleton.
- Feed it to the renderer as is (skipping renderer interpolation).
Here are console commands that help to test model in-game:
- Start a local server by
devmap <mapname> - Toggle third person view by
cg_thirdPerson 1 - Adjust view angle and range by
cg_thirdpersonrange&cg_thirdpersonanglerespectively
Following config script allows to use END button to toggle third person view & keyboard arrows for adjusting view angle and range:
bind END "thirdperson"
aliasa thirdperson "thirdperson_in"
aliasa thirdperson_in "cg_thirdPerson 1; cg_showHud 0; aliasa thirdperson thirdperson_out"
aliasa thirdperson_out "cg_thirdPerson 0; cg_showHud 1; aliasa thirdperson thirdperson_in"
