Map's blur and refraction

[maru]

Here is my problem. In the scene there is a one-sided geometry with a refractive (thin) material, lit by a Corona light, so that it projects shadows on the floor. When I move the camera away from the object, sometimes shadow of one of the faces gets very blurry. It has something to do with bitmap’s blur parameter. Images drz07_XX are rendered with different “blur” values.

Ok, I figured it out. This happens when the face is perpendicular to camera. So it’s because of texture filtering. Setting filtering to none solves the problem. This sucks and you have to be careful with it.

Thanx, very useful!

Fixed.

Shame on me for autodesk-range response time.

Merry christmas.
