HI, me again
I dl the trial of mudbox and I done a pair or test np,
also I did some NP using 3dbrush, for compare both the software.
The maps seems to be right:


but , using both the softwares ,the final risults is not that right:
Where in the highpoly models there are bumpies, the normal mapped models do shows indentations.
Many details ,done with Mudbox ,are missed also.

The shader seems to be works, there are some mistake in the detailing process.

Thanks for the shader, xXxGuitar511! And thanks for hosting, Spike!

Tried it with Lite-c and it worked very nice with the Doompack

EXCiter: Actually I've gotten some webspace from AienHeretic...

D3D: Thanks for testing it bro! Glad it will be usefull in A7 (if it's still needed), and that our users now know how to use it with Lite-C

ok i have included the litc version in my main.c file of the car test level but it is not showung NM as a mat file when I do the properties. did i do something worong ?

Code:

---

The mat_NM is already assigned when you attached the action SpinMe to the entity of your choice.
You can also attach the DLight action to a dummy model if you like. Try:

Code:

---

//////////////////////////////////////////////////////////////
// carlevel main.c: Load level,init physics, do camera control
//////////////////////////////////////////////////////////////
#include <acknex.h>
#include <default.c>
#include "physics_car.c"  //  <--- that's where the magic happens
#include "startup01.c"   // splash screen
#include "cg_add.c"      // Czeslaw Gorski actions
#include "NM.c"
//////////////////////////////////////////////////////////////

var camera_arc=100;
//////////////////////////////////////////////////////////////

function start_all();
function zoom_cam();

// global vars
FONT* fontArial = "Arial#20b"; // truetype font
ENTITY* pFocus;					// camera will orbit around this entity
var temp[3];
var temp2[3];

---

Note: copy/paste the relevant code from NM.c to main.c, or clean the NM.c script before including it to the mainscript of the carlevel demo.

OK so would i include the NM.c file into physics_car.c or would i need to copy certain parts of NM.c into the physics_car.c file


i hate when the only programmer goes on vacation. Not that I cant learn anything. But it takes a bit for me to catch on to stuff

Try make backup of carlevel directory and replace all code in main.c with:

Now reload the cardemo level inside WED and attach the action SpinMe to the entity of choice. You can also add the dlight.mdl to the level and if i'm right the action Dlight will be attached by magic. Rebuild the level and run.

Note: NM.fx,dlight.mdl must be in the carlevel directory.

OK i am not the best explaining stuff. what i am attempting to do is use the shader on a car. So it allready has the carinit actiono selected. And of course it wont run without the carinit action being assigned

Thank You

Tried to add the nm.c code to psysics_car.c and put init_normal(); in the main function of main.c, but that did not really worked, guess because the buggy has no normal map. So you must create one first and add it before apply the normal mapping shader onto the model.
