In the tutorial on making a still image, it was mentioned that the texel density of a building in an Enivironment piece is determined by what percentage of the render size it occupies.For example, if the render size is 1920 x 1300 and the height of the first floor walls is about half of the render size, the vertical size…
If you're trying to work out what texel density you need you should base your calculation on the closest view distance for the texture/object. calculating the correct density for a given view distance is simple if you know the FOV and target resolution - I'm sure its googleable but bear in mind that some renderers will…
