I have been working on an iPad build of my game and it looks great with antialiasing but, it seems that it slows right down when there’s a blob shadow in the scene. Before the blob it’s smooth, and the blob is set to only effect two ground objects in the scene so it seems weird that it pushes it over the edge so much.
Problem is, the character looks totally un grounded without a shadow but the game looks so much better with AA on the iPad… I’m kinda suck…
Does anyone know any way to optimise the blob shadow?
I’d just use a plane but my ground is uneven so that won’t really work. I thought I might try a decal shader but I’m not sure how that’ll work because the uv’s are broken up quite a bit.
Petey. The problem is not the AA with the blob shadow, but the projector itself.
The projector is very expensive to compute so it should be avoided. In my game, the blob alone made my FPS fall from 30 to 8!
So… consider using the plane again.
I thought I might have been doing something wrong but I guess there is no way around it. I am guessing you could use a raycast pointing straight down to get the position and then place a plane slightly above the ground?
