See the previous post. It is very unlikely that NVidia actually threw out these vectors. It only managed to optimize them out by detecting that ANY plausible tangent vector (which is always orthogonal to normal vector) would have led to the same result. So the optimizer happened to patch around the use of the missing data by chance.
The shader didn't change substantially functionally, it's mainly a .papa mesh file change. And NVidia was giving me tangents and binormals that worked with the normal maps I was using, so it was generating valid binormals and tangents, not just "any tangent". It was being sent over surface normals and texture coordinates, which are the two bits of data used to generate binormal and tangent vectors to begin with. So really all the data it needs to generate correct tangents was there, just the fact that they had code to do that is amazing.
Skitter: Bugs I used the patrol command with all the skitters - Skitter is not stuck, but just stops patrolling the area (Image 1) - Skitters are stuck in the lava (Image 2) Fabrication Bot: Bug - Fabrication bots won't assist building advanced energy plant (Image 3) AI (Hard): Bug - Continue Bumblebee build mode with commander assisting the air factory. (Image 4)
Also want to point out that link is somewhat inaccurate. There are two different sets of tangents which that author is conflating. There's a set of surface mesh tangents that get used to generate the base surface normal, which are then thrown out and ignored by most applications. Then there's the set of tangents that get used in conjunction with normal maps that are unrelated to the surface tangents apart from the surface normal itself and instead based on the texture UV space. edit: There's even some techniques that require ignoring the surface tangents completely and just use arbitrary artist authored surface normals.
My engineers really wont assit me :/ Forgot to make the cursor visible in Fraps, but im trying to assist the engineers by the Nukes, only when i move them very close they do the job.
