I didn't assign any action or material to them because I'm assuming that the shader is assigned to anything using transparency right... maybe?

---

no, you have to assign the material!

You must not set transparency, because then the polygons are not sorted. Only overlay, but no transparency or alpha channel (dont use a TGA skin).

I noticed that setting the entities ambient and albedo doesn't seem to work when using this material. Is that right? If so, what do I need to change in the material to adjust these?

---

maybe it's necessary to copy the mat_model material parameters to get the same behavior as with standard models. instead of the starter function this example uses a material event function:

Code:

---

function mtl_vegetation_init

{

	vec_set(mtl.emissive_blue,mat_model.emissive_blue);

	vec_set(mtl.ambient_blue,mat_model.ambient_blue);

	vec_set(mtl.diffuse_blue,mat_model.diffuse_blue);

	vec_set(mtl.specular_blue,mat_model.specular_blue);

	mtl.power=mat_model.power;

	mtl.albedo=mat_model.albedo;

	mtl.skill1=pixel_for_vec(vector(128,0,0),0,8888);

}



material mtl_vegetation

{

	event=mtl_vegetation_init;

	effect=

	"

	texture entSkin1;

	dword mtlSkill1;



	technique vegetation

	{

		pass p0

		{

			texture[0]=<entSkin1>;

			zWriteEnable=true;

			alphaTestEnable=true;

			alphaRef=<mtlSkill1>;

			alphaFunc=greater;

			cullMode=none;



			colorArg1[0]=texture;

			colorOp[0]=modulate2x;

			colorArg2[0]=diffuse;

		}

	}

	technique fallback

	{

		pass p0

		{

		}

	}

	";

}

@slacker: strange! i have no idea what could cause this. i use a gf4 too so this shouldn't be a problem... (try to add an empty fallback! )

My project owes you a 1000 thanks ventilator, for all of your shader support!

I think this is true for quite a few of us. We'll have to find out when that ol birthday is and send a present .
