This is really to show you how to texture properly, and its a nice and simple thing to make.
Difficulty - Pretty much as easy as it gets.
You should known basic controls for 3dsmax before starting this... but i'll make it as user freindly as possible.
And you'll also have to have experience in a photo editing program i.e. photoshop, paintshop pro.
You also need this Mars texture i made to start:
Create a sphere with the radius of 20cm, settings should look like this:
Right click, convert to editable poly:
Click subdivision surface, and choose settings like this:
Click the sphere so its selected, then press the M button, this will bring up the material window, like so:
Select the first picture of a sphere so it hi-lights it, then click the box with "Standard" written in it, this will bring up another window, choose multi/sub-object, then press ok:
Get rid of old meterial, then click the "set number" button, and put 1 in the box, then ok:
Click the material box as shown, then a new subwindow opens up, use the side bar to scroll down to maps, then click the "none" box for diffuse color:
A new wondow will open, choose bitmap at the top, then find the location of the mars texture (marstxt3ex.bmp should be the name of it):
Now then, we have the texture ready, tab out of 3dsmax, we now need to make the bump map, and the reflection in a photo editing program, so open yours up, then open your marstxt3ex.bmp.
Im using paintshop pro for this next bit, but hopefully you'll understand what to do in your program.
Ok, duplicate the layer, and then you need to take all the saturation out of this layer (make it grey scale):
Now you've done that, you'll need to invert the colors, and then raise the contrast abit.
Because its a bump map, black means low, and white means high, so this will be the rocky 3d parts of the planet.
This is how it should look by now:
Save this as a .psp, .psd or whatever supports layers, call it something like mars layers.psd or whatever, it doesnt matter really.
Now, duplicate the black and white layer, and this time you want loads of contrast and invert once again.
This is the reflection, The white bits will be converted into a shine effect.
It should now look something like this:
You now need to save the first black and white layer as mars bump.bmp, and then the second one as mars reflect.bmp:
Ok, tab back to 3dsmax, and then click the little box with the three balls, and the arrow poiting up (go to parent):
This will now bring you back to the subwindow with the maps tab, click the none button next to bump:
Choose bitmap again, and find mars bump.bmp, click goto parent and then click on the none tab next to reflection:
Then bitmap once again, find mars reflect.bmp, goto parent, and now you see the numbers in the middle, most of them are at 100, this means 100% so change them to this:
Click the assign material to selection picture box, then the show map in viewport box:
You can rotate your new planet at this point to get a good perspective, just use the tools in the bottom left corner.
ok, you can close the material box now, and i'd also advice you to save your progress as your almost finished.
all you gotta do now is click the rendering menu in the toolbar, then render, and a new window will open:
Now, all you need to do is set the res to 800x600 for a clearer picture, and click render:
Thats it your done...it should have only taken around 30 minutes, depending on how well you know the programs.
This is the final tutorial peice, and a real pic from the hubblespace teliscope:
You can make starry back drops just using a plane, with a starry texture slapped on top of it.
Using hi-res pictures will add more detail to the render,and make it look more realistic looking.
If you want to request a texture for a certian planet, or satalite texture, just pm me.
If you have any problems with any part of this tutorial just post, and i'll reply as soon as i see the post.
I hope this helped you get used to the texturing, and you'll go on to produce some nice work.
