i’ve noticed a different behaviour about dx11 texture transform (in constant, gourad, phong ecc shaders), that i cannot understand.
my goal is to use a texture over a spread of objects. i’m attaching a better explaining patch, with the dx11 and dx9 same things in comparison. the dx9 behaviour is what i want to achieve in dx11. but i don’t know how
after some testing i found your method was not completely correct (try for example to move the phase of linearspread or something like that.
but your patch pointed me out to the right direction, that is not reversing the y, but multiply by -1 it, as in the attached patch, thank youu ;)
yes, about phase i mean translating the pieces of the grid (or for example if it’s not a grid, but something more random, like a randompread, possibly in 3d).
Simply the reversed spread worked because the values was specular (negatives and positives) because the grid had 0,0,0 as center.
