It convert a Silkroad MOdel File to an Wavefront OBJ file
You can view OBJ file with Blender, or with this XNA Sample

XNA Sample:

You can find Models and Textures here:
Data.pk2/prim/mesh/ = MOdels
Data.pk2/prim/mtrl/ = Textures

To Convert a ddj file you need a HexEditor like XVI32
Then delete the first 20bytes and then save as *.dds
DDS can converted by "DDS Converter 2"

Many Models are saved in more then 1 *.bms file

[moderiz11]

And obj back to silkroad format?

[chea77er]

I will try to code an OBJ to BMS today in the evening

[moderiz11]

New weapons mods here we come

[soadmania]

Awesome work

[Nezekan]

OBJ => BMS would be awesome, after all these years...

its better and faster too use this tool:




its not from me this converter

thank you my friend

[playerh007]

chea77er is it possible that you try to code BMS=>OBJ

that would be great

(sry i know that this threat is very old but i need it)

[flatro21]

Ohh so good word gz dude.

[chea77er]

sry guys, i got some request for OBJ to BMS. But there are some informations which i don´´t know what it is. In my code you can see that there are many bytes which aren´t converted.. so you can try to make OBJ=>BMS without this infos just replace the jumped bytes with 00 or something. don´t know if thats work.

I have no time to check this.

[jhondelle]

thanks.. too ^^

[darky666]

i dont know if anny1 is still watching this tread

but if you want to experiment with this you will have to collect the garbage
(just google it garbage collect C#)

because if you start the vieuwer it uses up all your memory then it crashes

other then the memory usage its a nice program

[bootdisk]

Garbage collectors run in background, the only platform in which it was needed to force a call was at j2me.

Debug the code and I'm sure there must be an infinite loop, as perhaps, most of the structures have changed from chea77er release to today's silkroad version.
