Could detail some 'gleaned' info., but it won't be of much use to you without a detailed explanation from a BIS developer. The 'content' of the file has diminished from the rtm_0101 format in so much that the older version specified a 4 x 3 (standard) transform matrix whereas the 'new' binarized version only specifies 7 floats per bone per frame. Even if you include the 'total moving' this still only gives you 10 floats so not enough to define the standard transform. | Could detail some 'gleaned' info., but it won't be of much use to you without a detailed explanation from a BIS developer.

Supposition is that possibly BIS have implemented 'size/scale' independent anims that then 'perhaps' take thier 'scale' from the model being applied too, that's speculation though. | Supposition is that possibly BIS have implemented 'size/scale' independent anims that then 'perhaps' take thier 'scale' from the model being applied too, that's speculation though. | ||
I'm sure the tools should be out soon enough and perhaps an actual explanation might accompanying them regarding this topic. -- [[User:Sy|Sy]] 09:45, 2 July 2009 (CEST) | I'm sure the tools should be out soon enough and perhaps an actual explanation might accompanying them regarding this topic. -- [[User:Sy|Sy]] 09:45, 2 July 2009 (CEST) | ||
-------------------- | |||
the new file format has been published | |||
[[Rtm Binarised File Format]] | |||
for the most part it has simply removed the enormous redundancy of information in this, unbinarised, version. | |||
However, as Sy points out, the 7 'floats' are a total mystery. | |||

- Any chance we could get a rough sketch of the new RTM files please (the ones starting with "BMTR")? It would save us some sleepless nights and lotsa' byte counting.. teaCup 01:43, 2 July 2009 (CEST)
