Hello,

I have a problem on my customer's iR system w/ Perf2.1.

When eye-point is far from the Point-Rot Billboard model, model seems
rendered properly.
# In fact, I use billboard model to render Sun.
# It's modeled as 1 rectangler polygon with a texture.
# At the far place, it faces eye.

However, as I move eye-point to close to the model, model's face direction
reverses gradually, and It's faced to overthere at last.

Perf2.0 & Perf2.0.1 worked properly about this.

Does anyone have any workarounds ?
Any help will be greatly appreciated,

Thanx,
