Hi, While rendering to terrainData.heightmapTexture I discovered that writing 1.0f to pixels doesn't result in terrain of maximum height (as specified in "Terrain Height" inspector field) but 0.5 does (1.0 is twice that and not available for manual brush edits). Seems odd/surprising but I expect there is sensible reason behind it. how much money to buy a car

Web説明. Perlin noise is a pseudo-random pattern of float values generated across a 2D plane (although the technique does generalise to three or more dimensions, this is not implemented in Unity). The noise does not contain a completely random value at each point but rather consists of "waves" whose values gradually increase and decrease across ... how do i share media files
