Maxscript: How to enable a button from a custom material?

nyx702

My company has a custom .fx 3d  Max material and I'm trying to hack together a script to automatically assign texture to it. I have it working however the box with the texture name is "disabled" and I'm trying to figure out how to enable it. I don't really even know what to search for. 

 

This is the code from the material rollout

group "Base"
(
 checkbox      cbox_diffuse        "Diffuse . . . ."  	    align:#left across:3 offset:[0,0]
  mapbutton     b_diffuse           "None"             	    enabled:false align:#left height:16 width:190 offset:[-20,0] 
)

The basic test of what Im doing is this. Asking for a file via prompt and assigning it.

n askForfile =
(
	fileD = getOpenFileName caption: "Pick ur " \ 
									types:"Targa(*.tga)" \
)

fn assignDiffuse = 
(
	
	meditMaterials[curMet].g_DiffuseTex = Bitmaptexture fileName:fileD
	meditMaterials[curMet].g_bDiffuseMap = on

)

The thing that is confusing to me is the listener calls the diffuse "g_DiffuseTex" and in the actual .ms its called "b_diffuse"? The scripts are kind-of a mess and I'm a newb so that is a bad combo. I'm not sure what other info would be helpful without posting the whole mess of scripts. I'll post what I can without getting into trouble.

its g_DiffuseTex as thats whats the texture sampler called in the shader. Pretty sure as I wrote something back at my old job where it accessed engine materials and was setting it up in max. It might be  disabled because of this? (enabled is set to false): mapbutton b_diffuse "None" enabled:false
This WYSWIG editor is funky haha

Haiddasalami, is right about b_diffuse being disabled. I assume you are not allowed to change that part though.

But really you don't even need to enable b_diffuse to work just do something like this:

(medit.GetCurMtl()).RolloutName.b_diffuse.picked (bitmaptex filename:pathToFile)

This will make Max think you pressed the button.

@haiddasalami 
I tried enabling it but I'm not sure if I was doing it right or if it just doesn't work. I tried 
meditMaterials[curMet].b_diffuse.enabled  = true
and
meditMaterials[curMet].g_DiffuseTex.enabled = true

but neither of those worked. The listener said, "Unknown property: "enabled"

@monster

Awesome! That is what i was looking for but couldn't find out how to "press" a button... How do I find the RolloutName I need? Is there an easy way to do this in max without opening the script file? I tried the displayed name but that didn't work.

Try this Nick. 

meditMaterials[curMet].g_DiffuseTex = openBitmap "Insert Path to test"

That should load a texture to that sampler. Guessing this is a scripted material plugin? Hard to debug from here but not sure if you know but you can do for example

b = medit.GetCurMtl()
show b
