So if that bit is not set, it should work normally?

pegperegogaucho

Indeed!

hesopesomeso

Yeah.

hesopesomeso

Well, they are called external flags, but I guess there's nothing :KEKW:

pegperegogaucho

I guess the reason why it has not been a problem before, is that obviosuly most nodes you see are transformed and then the flag is not set. But for some reason, the flag is not set for the child nodes of the helmet cages in Rome. Oversight by the devs? Why would they even need to set this super internal flag themselves? And Is the reason why those OBBs are size (1, 1, 1) because they tried fixing it? :KEKW:

adrientd

There may be situations in the editor where for example only the translation is changed (last row) so the flags are kept, if that that flag happens to be set, the editor will not update the flag if the matrix is no longer identity.

hesopesomeso

They prolly used RwMatrixSetIdentity, which sets the flag?

pegperegogaucho

Yeah, but the node is translated but the flag is still set...

hesopesomeso

Forgot to do those. I wonder whose job that was :KEKW:

pegperegogaucho

So maybe KAL translated it but the flag was not set and some poor frenchman had to change it manually

pegperegogaucho

Also, I don't understand the point of this flag. is this just used to quickly check if the matrix is an identity without checking the elements?

hesopesomeso

Yeah, for optimization.

hesopesomeso

poor frenchman :Obelul:

pegperegogaucho

I guess back then the matrix multiplication was slower than the branch

hesopesomeso

It's the same now on a CPU.

hesopesomeso

Very confusing header, but the 0x3 is `rwMATRIXTYPEORTHONORMAL`: `RwMatrixOrthoNormalize` does set it, so I guess that's that?

pegperegogaucho

Makes sense it is orthogonal

pegperegogaucho

also if the matrixinternalidentity flag is 0x20000, so the third byte, then what actually are the external flags? :Obelul:

hesopesomeso

External flags is the RwMatrixType, and internal is RwMatrixFlag.

pegperegogaucho

It must be useful to have all the RW headers
