Chams

​

Features

​

Entity Types

• Render other players through walls
• Self - Show your own player model (requires third-person or Freecam)

• Highlight end crystals through walls
• Essential for crystal PvP awareness

• Apply chams effect to your hand/held items
• Creates a glowing hand effect

​

Visual Settings

​

Colors

• Inner color of the entity model
• Default: Blue with 25 alpha (transparent)
• Lower alpha = more transparent

• Outline/wireframe color
• Default: White with 255 alpha (solid)
• Set alpha to 0 to disable wireframe

​

Effects

• Changes blend function for a shiny/glowing effect
• Uses GL_ONE_MINUS_CONSTANT_ALPHA blend mode
• Creates a brighter, more vibrant appearance

if (shiny.getValue())
  GL11.glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_CONSTANT_ALPHA);
else  
  GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

• When disabled, respects depth testing (entities behind walls are dimmer)
• When enabled, renders at full brightness through all blocks

if (!walls.getValue())
  RenderSystem.enableDepthTest();

​

Rendering Modes

​

Standard Mode (Cancel = false)

• Normal entity renders first
• Chams overlay renders after
• Both are visible

​

Cancel Mode (Cancel = true)

• Vanilla rendering is cancelled
• Only chams rendering is shown
• Applies model animations manually
• Renders feature layers (armor, items, etc.)

if (cancel.getValue()) {
  event.setCancelled(true);
  // Manual rendering of model, animations, and features
}

​

Configuration

​

Shader Integration

• Custom model rendering via ChamsModelRenderer
• Shader-based color application
• Depth buffer manipulation for through-wall rendering

​

Player Model Rendering

if (entity instanceof PlayerEntity) {
  ChamsModelRenderer.setupPlayerTransforms(
    (AbstractClientPlayerEntity) entity,
    matrixStack,
    animationProgress,
    bodyYaw,
    tickDelta
  );
}

• Proper body rotation
• Smooth animation interpolation
• Correct pose (standing, sneaking, swimming, etc.)
• Feature rendering (armor, elytra, items)

​

Hand Rendering

ChamsModelRenderer.renderHand(
  matrices,
  tickDelta, 
  wireColor.getColor(),
  fillColor.getColor(),
  1.0f,
  wireColor.getAlpha() != 0,  // render wireframe?
  fillColor.getAlpha() != 0,   // render fill?
  false
);

​

Integration

• Shows self chams when in freecam mode
• Freecam.INSTANCE.isEnabled()

• Respects visualize rotations when rendering
• Adjusts head yaw/pitch for anti-cheat visualization

• Skips rendering when FROM_INV flag is set
• Prevents conflicts with inventory-based rotation spoofing

​

Visual Tips

​

Performance Notes

• Chams renders during RenderWorldEvent with MANAGER_FIRST priority
• Range limiting prevents rendering distant entities
• View distance culling: only renders entities within loaded chunks

double d = (mc.options.getViewDistance().getValue() + 1) * 16;
if (player.distanceTo(entity) > range || x > d || z > d) {
  continue; // Skip rendering
}
