I’ve just tried to use scalar param and it worked but started to give me weird results which wasn’t good enough, I’m trying to draw to a render target and having the trail fade over time from oldest drawn to newest.
I did think of an alternative solution but it depended on the SetTextureParameterValue function which doesn’t seem to work? could be a bug or doesn’t work the way i think it does.
I’ve drawn a picture to hopefully better explain what i mean.
