Texturing in 3DS Max (any version)

Preparing the CMP for exporting/ Sur splicing.

Right. I thought if im going to write the tutorial explaining how to texture, i might as well go all the way and explain how to prepare the CMPs for Sur splicing. Problem is, its kind of hard to explain with words, but i will try my best to explain it as simply as i possibly can.

Preparing the groups:

Right. This part requires a bit of your own judgement and decision making. You need to look at your model, and rightly guess how many different CONVEX primitives (ie boxes/cylinders etc) will it take to make a fully fitting, as accurate as possible hitbox for your model. Bear in mind, if you are creating a station etc, you have not got any other choice but to use the Sur splicing method to create the hitbox anyway, so youll have to go through all of this process anyway.

Looking at this model, i approximate that it would take me about 14 primitives to hitbox, assuming i wish to make the hole in the hitbox like the mesh has if you can spare mesh groups , then go for it, but remember, the hitbox must cover 100% of the ship before you worry about details for the hitbox. The next step involves breaking the model up into 14 groups accordingly.

REMEMBER: due to the way the cmp exporter is currently setup, we are limited to 18 mesh groups per cmp. There ARE ways to pass that limitation, however, that requires alot of work, and ill let you master the basics before i begin the next step for obvious reasons.

To split a mesh in 3ds max into different groups, you need to make sure your model is already an editable poly. Once you make sure, you need to go into polygon mode, and start selecting ALL the faces you wish to detach from the main group to make a new group

As you can see in the image above, after you select all the faces, you need to hit the button on the right hand side option set called detach. It will open a new window prompt, asking you to give the detached mesh a new name. MAKE SURE YOU GIVE IT A SENSIBLE, UNIQUE NAME. Do NOT call it box 1, instead try something like.. central body. Furthermore, AVOID USING NUMBERS WHEN NAMING THE GROUPS. I will explain why further on.

As you can see, i ended up with 15 groups. Remember, the initial approximations do not necessarily have the be exactly how it turns out- that depends on how you wish to split the mesh up, as long as the hitbox which you make covers the mesh as best and as accurately as possible.

The next step is for you to download this script, and put it in the Scripts folder for your 3ds max 9. While youre at it, download this obj exporter for 3ds max (this is slightly different than the wavefront obj exporter, but works 100%). To install the exporter, just drag the icon into one of your viewports and drop, it should automatically install it.

The next step is important, pay attention. You need to re-arrange the groups there according to how they are connected. Remember, the each mesh you group must be connected in some way to another group, and as such you need to set them up in the window. Now, Click on the button on the top tray that when highlighted says Schematic view. This button is on the left hand side of the material editor button. Once open, youll see a new window with loads of blue/purple coloured buttons. As you can see in the image below, ive re-arranged the groups properly so each group is touching the next group in the cmp

Before you do anything, you need to press the button called connect (third button on the tray), followed by the hierarchy mode button (sixth button on the tray. Once youve done that, you need to click on the blue button on the right hand corner (in this case, exhaust three), drag your mouse whilst clicked onto the next blue button (exhaust two) and drop once your mouse is above the exhaust two box as shown below:

You will need to do this from right to left for each box, so you click, drag and drop onto next box, then from the box you dropped on, you click, drag, and drop onto the next box until you have something like this:

Next step involves using the plugin you just downloaded from me. Close the schematics window, click on the option called MAXscript, click on the option called Run script, it will open a new window. Select the script that is called detachbyID, and click open. This will open a new window. MAKE SURE YOU HAVE THE SAME SETTINGS AS I DO AS SHOWN IN THE SCREENSHOT BELOW:

If everything is as it should be, youre ready. Click on DETACH button. This script will detach the meshs groups and prepare the cmp to be just like how the cmp would be in milkshape (3ds normally doesnt do this due to being far superior than milkshape etc, but using this script will help you when you export your model to milkshape to prepare the cmp)

What you end up with after detaching is a multicoloured mesh. Click on the schematic view option again, and youll notice instead of the initial 15 groups you had, youll have alot- more now. What this script has done is it has split the mesh up into subgroups per mesh. In milkshape, you get groups based on what texture is applied per face. This script has done exactly that, split up the sub groups inside each mesh according to the textures applied to the faces, but it has kept your overall 15 groups total. (this bit may be a bit hard to understand, and i cant exactly word it properly, if you still need further assistance understanding this part hit me up on skype [Gurjiv.singh is mine, afaik] and ill try and explaining it as best as i can).


What you need to do is re-arrange the groups again if need be ( i will have to) so that each subgroup is grouped together before you move onto arranging the next mesh. Hopefully the screenshot will be able to explain better:

After you re-arrange the groups, you do the same step as before. You select the connect button, then hierarchy mode button, and from right to left, start connected all the groups again. Close the schematics mode window once youre done connecting.

Congrats. Part one of the tedious journey is complete. Next, you need to export the mesh for the second step to creating the cmp via milkshape. Click on file -> export, and in the options, select the new obj format (youll see it right below the wavefront obj option in the dropdown), give it a name, and click export. When you do so, youll see a new window opens up. Make sure the settings are EXACTLY THE SAME as shown in the screenshot below:
