I cannot find a way to export textures with 16-bit colour resolution in Marvelous Designer.
Being able to only export 8-bit textures becomes a problem with normal maps because the 8-bit colour values cannot store precisely flat colour vectors. When dealing with floating point values, a flat surface is defined as [0.5,0.5,1], where 1 represents white.
The maximum value, or white in 8-bit textures is 255, cannot be divided in half and remain an integer, so 127.5 is rounded to either 127 or 128. This causes "flat" areas on the textures to be slightly not-flat and you get inaccurate shading.
The maximum value of 16-bit textures is 32 768, which can be perfectly divided in half to 16 384.
16-bit or higher colour resolution is required for accurate normal maps.
If it's currently not possible to export 16-bit textures please consider implementing it because it is quite important for us users who care about accuracy.
Thanks!
