3D Studio Rendering problem A corner of a room. A rectangualr wall object built with a box, with planar mapping Coordinates and a 24bit TGA texture of bricks, intersects in 60 degree angle with another wall of the same characteristics and a floor object built by getting a shape from the 2D shaper. A 30 mm camera runs parallel to the contiguous wall. When rendering this simple animation , on some few frames, the texture map of one of the walls appears distorted as if it had been pixilated or boxilated. It only occurs in one of the walls and only in some frames of the animation, as if the distortion was related to the angle in which the camer is targetting the wall. There does not seem to be a specific patter to the relation between the camera angle and the wall. This corner situation is repeated in several places within a model. Depending on the specific corner location we get different variations. In some corners there is no problem at all. In some corners the distortion occurs at the beginning of the turn, when the camera is perpendicular to the wall, sometimes it occurs in the frames when the camera is turning and the wall gets very close to the camera and sometimes it occurs at the end of the turn when the camer is parallel to the wall. Any explanation? we can provide example images if necessary. These problems have been noticed in version 2 as well as 3. Adrian Cook ajc@epic.co.uk
