IMHO the description of the content of the MDLH section is not correct. "MDLX" is part of the RIFF header, the MDLH section seems always to contain 1 integer with the value of 123456 and 1 float with the value of 10; I assume that is a kind of file signature. osman
You are correct Winfried. I realised this after I had typed it, but I haven't had the time yet to update it. Will try to do that ASAP. Arno
I have updated the document now. I see the same parameter in the header section indeed, so it seems they are sort of constants. I have no idea what they mean (10.0 might refer to the version of FS????). Arno
I have looked to the VERB section of a rather large mdl file (one of the default aircrafts). There I see that the VERT and the TANS sections are repeated several times (always one TANS section following one VERT section). I wonder how this is reflected in the PART structures referring to the VERT sections, have you any idea ?) osman
I would check the first two parameters of the part section, I suspect on of them is refering to the vertex buffer used for that part. Which object are you looking at, then I'll take a look. Arno
I was looking to the Airbus_A321.mdl.
The CRAS section apparently is different from the one in FS2004 (although it is still an octree). It has first two unknown integer values, then there are 3 float values giving the lower left corner of the object, then 3 float values giving the length, height, and width, then another unknown int, and then the branches of the tree, which are now all integer values instead of bytes (apparently -1 replacing oxff and -2 replacing 0xfe).
The ANIB section has several subsections (RIFF, XANH, XANL). And after that we have a REFL section if any points have been attached to the object, with a REFP subsection for every attached point and a ATTO section for every point which has something attached to it describing the attached object. osman
I took a look at the A321 model at well and if I look at the values in the PART sections I think the sceneref value refers to the vertex buffer being used. But I have not verified that yet, to do so I would have to visualise the model and see if it looks ok :).
PS. I don't know what you prefer, but I guess it would be easier to have discussions like this on the forums. OK, so, I will continue with questions on the forum osman
