| 1. Why does my HeatHaze object render entirely (or with patches of) white? This is because the object is not being rendered using Single Sided. Note that there may also be problems if the HeatHaze object is more complex than a simple primitive - basically, if any “outside” (single sided) face is visible through another “outside” face, then the shader will not render properly. |
| 2. Is there any way of adding more detail to the effect? You could try adding a bump map, as this will add to the distortions. Also, you could try animated the shape of the HeatHaze object - if using a cylinder, for example, you could animate vertex changes to it, or use a deformation object moving along the length of the cylinder. |
| 3. Is there any way of adding colour to the HeatHaze object? No. For the sake of speed, and for ease and flexibility of use, the HeatHaze shader does no surface calculations at all (no diffuse, ambient, specular, etc). Normally, the HeatHaze object is used to surround another object, so if you have a flame for example, then you texture the flame as normal, and surround it with the HeatHaze object. Similarly, you could add another object inside the HeatHaze object if you wanted to have a coloured distortion of some sort (smoke, underwater eddies, or special effects). |
