unique material per entity ?

I need to do some changes in the shaders of my entities, stuff like bump strength and so on, i noticed however, that changes done to one MATERIAL affects every entity with that material, first solution that came to mind was to use MTL_CREATE for individual entities, that works.. but theres a visual delay when the entities get created, so with that i looked into using PRELOAD_MODE=3+4; not much difference with that either, i was looking ant ent_cloneskin but didnt seem to get any results, so question here is, what can be done to get this working for varying meshes? Is ent_cloneskin the way but i'm not using it right?

Use vecSkill41 and set skill41 to 45 via script (with the floatv command). There's vecSkill45 for four additional skills.

that is what i do to change shader parameters, via using skills and floatv ... for example: vec_set( myMtl_AiShader.skill17, vector(floatv(tmpVar), floatv(tmpVar), floatv(tmpVar) ));

use the entity skills inside the shader, not the material skills.

how would i go about doing that?
i cant just change: mtl_Shader.skill18 = floatv(1) to my.skill18 = floatv(1) right? because i got no results... i would have to make changes in the shader file also i assume right ?

OK i got it, thanks people, made use of entity skill41 .. skill44 and skill45 .. skill48

Didnt think of that before, first time i'm jumping this much into shaders
