Making normal maps for your decals

have seen a few people wondering how to do this. this is also how to make it so your track has terrain shaders.

step 1: open your decal in photoshop not to sure about other programs. gimp i think works abit like this

Image

step 2: duplicate the layer (your decal)

Image

Step 3: now make a new layer and put the layer in the middle of the two decals

Image

your layers should look something like this

Step 4: paint the blank layer entirely a grey colour

Image

Step 5: Select your decal and press ctrl+shift+u and your decal will turn a shade of grey

Image

step 6: merge the now grey decal with the solid grey layer

Image

this will be the result

step 7: apply this normal filter to the layer (the normal filter can be downloaded here: https://developer.nvidia.com/nvidia-tex ... -photoshop , to get to this filter you go filter > NVIDIA tools > NormalMapFilter)

Image

up will come a new tab change your setting to this

Step 8: Now press OK

Step 9: to make the normal map more intense, duplicate the norm and go to were it say normal click so the drop down bar goes down a select overlay so that it makes on of the norms and overlay (you will know as the norm map will suddenly get much more intense) continue this till you are happy with the out come.

Image

where you go to change it to normal

before the overlay

Image

after

Image

(you dont have to make it this intense or you can make it more intense, this was just for tutorial sake)

Step 10: Save it in the same place as the decal you are using for your track but name it "decal name"_tnorm
another thing that will needed to be changed is your lighting file. 'dynamic_lighting 1' will need to be added to the end of your lighting file for oyur norms to work.



i hope this helps someone, this works for me may not be how others do it but it works. you can comment if you think something may improve the norm.

also a big part of having a awessome decal is the spec. but that is for another day and time.

Like I said there would be many ways this is just how I do it. Only did it as I had this trouble when I was learning and as I have seen many other people questioning and wondering

Not to be the biggest dick munch but you really should have alpha-ed the edges or overlapping textures will look terrible.

Thanks so much.

But for alpha-ing the edges or whatever, wouldn't I just check the box that's says "Alpha Blending", or is there something else to it?

You can also make them more "intense" by making the number in the scale box larger. I also use image>adjust>levels to make sure I have almost full white and full black and put it on a black layer so it will be more intense.

For some reason, this hasn't worked for me...

You mention specular maps as well... Is there any "offical" documentation from JLV on this? I'm having trouble finding anything on the subject of normal and specular maps.

I have got the base game, and updated it with the latest snapshot. Is there anything else I need?
