DMX/Source 2 Vertex attributes
< DMX
The DMX mesh format (Version 22) supports arbitrary mesh attributes. The Source 2 tools can make use of many attributes besides the standard ones to control per-vertex model features.
Note:The list is very likely incomplete.Standard
| Attribute | Type | Description |
|---|---|---|
| position | vector3 | Vertex position. |
| normal | vector3 | Vertex normal. |
| texcoord | vector2 | UV coordinates. A second UV map can be added with texcoord$1. |
| blendweights | float | |
| blendindices | int | |
| wrinkle | ||
| balance | float | |
| tangent | vector4 | |
| speed |
Vertex Color Maps
| Attribute | Type | Description |
|---|---|---|
| color | vector4 | Vertex color. Can be used in the VR shaders to tint a model with the appropriate material attribute enabled. |
| VertexPaintBlendParams | vector4 | Used to blend between texture layers in bland materials. Works the same way as the Hammer Terrain Blending tool. |
| VertexPaintBlendParams1 | vector4 | Todo: Unknown additional blend parameters
|
| VertexPaintTintColor | vector4 |
Cloth Simulation
| Attribute | Type | Description |
|---|---|---|
| cloth_enable | float | (0 - 1) Enables cloth simulation and creates a cloth node on the vertex when set to 1. |
| cloth_animation_attract | float | Legacy parameter deprecated in favor of cloth_goal_strength. |
| cloth_animation_force_attract | float | Legacy parameter deprecated in favor of cloth_goal_strength. |
| cloth_goal_strength | float | (0 - 1) Controls the how much animations influence the vertex position. |
| cloth_goal_strength_v2 | float | (0 - 1) Todo: Same as cloth_goal_strength?
|
| cloth_goal_damping | float | |
| cloth_drag | float | |
| cloth_drag_v2 | float | |
| cloth_mass | float | Todo: This sets the per-vertex mass in kg, but doesn't seem to go below 1, leading to extremely massive cloth. Enabling explicit masses ignores this value, contrary to documentation
|
| cloth_gravity | float | |
| cloth_gravity_z | float | |
| cloth_collision_radius | float | |
| cloth_ground_collision | float | |
| cloth_ground_friction | float | |
| cloth_use_rods | float | |
| cloth_make_rods | float | |
| cloth_anchor_free_rotate | float | (0 - 1) Controls how freely cloth nodes bordering to non-cloth vertices can rotate. |
| cloth_volumetric | float | |
| cloth_suspenders | float | |
| cloth_bend_stiffness | float | (0 - 1) Controls curvature of bend springs. Requires m_bAddStiffnessRods to be enabled.
|
| cloth_stray_radius_inv | float | |
| cloth_stray_radius | float | |
| cloth_stray_radius_stretchiness | float | |
| cloth_antishrink | float | |
| cloth_shear_resistance | float | |
| cloth_stretch | float | (0..+inf) A value of 1 gives extremely loose cloth. Strechiness increases exponentially with value. Todo: Does this affect both quads and rods?
|
| cloth_friction | float | |
| cloth_collision_layer_0 - 15 | float | |
| cloth_vertex_set_<set_name> | float |
