I have one set as my wallpaper for inspiration.. and frustration. @Ventilator - I thought I'd let you know that I have already included you in my "poeple to thank" credits for this project. Heck, I should list you as head programmer .

I am running 6.20 commercial with a ti/4200 my object is single sided polys with a texture and alpha. I am pretty new to this stuff, any help is greatly appreciated. material mat_overlay { 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; } } "; } starter mat_overlay_init { mat_overlay.skill1=pixel_for_vec(vector(127,0,0),0,8888); } action matoverlay { my.flare = off; my.transparent = off; my.material = mat_overlay; } p.s. can someone help me get formatted code into these forums?!

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! )
