detail_texture

---

This extension allows users to define a detail texture, which adds detail to objects under extreme texture magnification. The textures are only supported in 2D.

• Although the extension provides for the detail texel to be modulated or added to the level 0 texel, IMPACT only supports additive detail texturing.
  
  
• Detail textures in IMPACT are restricted to two sizes: 128x128 and 256x256.
  
  
• Tuning Tip:
  For best performance, set the detail texture level to <= -3 and detail texture function such that the contribution at LODs > -3 is zero.
