good morning comm!!

well, a question to all that shadergurus out there: is it possible to manage shaderparameters depending on gamevars?

example:
the saturation (or any other parameter of a shader) of a texture (of a model) should be definend by distance to the player; if the player is nearby or is less then xy quants to the object the saturation should not be modified; if the distance between player/object grows, saturation should be reduced depending on the the dictance until saturation equals zero;

is it possible to do this EASY??

thanks for paying attention

it is. look for vecSkill1 in the manual.

it is sorta easy but the manual makes it more confusing than it is.
the entity has skills and skill 41-44 are sent to the shader.

in the shader these values can be obtained thru 1 float4 for called vecSkill1.
note all of these values are in vecSkill1

skill41=vecSkill1.x;
skill42=vecSkill1.y;
skill43=vecSkill1.z;
skill44=vecSkill1.w;


also when ever sending a value this is incorrect:
skill41=my.pan;

since a7's variables are different then a shader float you need to send it like this:

skill41=float(my.pan);

That is not right lostclimate
Each material has skill1 to skill20 those can be accessed from a shader through float4 vecSkill1; //skill1-4
float4 vecSkill5; //skill5-8
float4 vecSkill9; //skill9-12
float4 vecSkill13; //skill13-16
float4 vecSkill17; //skill17-20

And there are also the entityskills 41 to 44 (41 to 48 since A7.07) which can be accessed from a shader through:
float4 vecSkill41; //skill41-44
float4 vecSkill45; //skill45-48

If you want to pass a gamestudio var to a shader you have to use floatv() (float() with A6) to convert it to float.

You can also pass one matrix to a shader (8 with the latest beta). Just set the material matrix and use it within the shader as float4x4 matMtl.

??? i thought he was talking strictly about entity skills (not mat skills,) but either way, i thought 41-45 only went to one float4 that was accesible

Also, I think you need to convert the value to a float:

mtl.skill1 = flloatv(SomeValue);

Thanks ^^

thx guys, now i know in which direction i have to do my "tests"
