bitmap switcher

Submitted by ste on Thu, 2014-07-03 16:51

Another script...another newbie problem!

I'm trying to develop a script that let me change diffuse texture of a certain material.
I started studying Joe Gunn old script "face switcher": this script change material ID (but first we need to create a multiamterial with a lot of submaterials with different textures), while I think it's faster to have only one material and change its texture.
The script let you choose a directory to sort bitmap from, create thumbnails and...nothing.
The scope is to change material texture clicking on the corresponding thumbnail and to create a keyframe for material diffuse slot.

This is my result:

try(destroyDialog ::texchange)catch()
rollout texchange"TEXTURE CHANGE"
 
(	
--interface
	button btnSetD "Set Dir:" pos:[5,5] width:50 height:20 toolTip:"directory immagini"  
	edittext Fdir "" pos:[55,5] width:100 height:20
	button btn01 "01" pos:[5,30] width:30 height:30  
	button btn02 "02" offset:[-30,-35] width:30 height:30
	button btn03 "03" offset:[0,-35] width:30 height:30  
	button btn04 "04" offset:[30,-35] width:30 height:30
	button btn05 "05" offset:[60,-35] width:30 height:30
--choose bitmap path
	on btnSetD pressed do
	(
		local curpath = Fdir.text 
		local newPath = getSavePath initialDir:(curpath) caption:"Select the path where your Face Images are located" 
		if newPath != undefined then	
--create thumbnails
		(
			Fdir.text = newpath
			btn01.images = #(Fdir.text + "\01.png", Fdir.text + "\01.png", 1, 1, 1, 1, 1)
			btn02.images = #(Fdir.text + "\02.png", Fdir.text + "\02.png", 1, 1, 1, 1, 1)
			btn03.images = #(Fdir.text + "\03.png", Fdir.text + "\03.png", 1, 1, 1, 1, 1)
			btn04.images = #(Fdir.text + "\04.png", Fdir.text + "\04.png", 1, 1, 1, 1, 1)
			btn05.images = #(Fdir.text + "\05.png", Fdir.text + "\05.png", 1, 1, 1, 1, 1)
		)
	)
--actions
	on btn01 pressed do
	(	
--and here the problem... load 1st thumbnail image to object material
	)
	on btn02 pressed do
	(	
--same, and so on...
	)	
)
createdialog texchange 160 200 10 110 style:#(#style_titlebar, #style_sysmenu, #style_toolwindow)

I hope to have been clear enought... any idea?

Great job!!!

Could you please share this script? I would be very useful.

thank you very much

Thanks!

It could be a good tool, but I really need some help to finish it because it's full of bugs!!

Here the complete and commented code (I forget something... but some time has passed, sorry).

I have attacherd a zip file containing the script, a simple scene (max 2010) and 2 textures just to speed up testing process.

----- FACE SWITCHER V.0.1
----- This is a scripted modifier
----- It allows you to change object texture editing bitmap cropping and placement
 
----- INSTALLATION:
----- put this file in ...maxfolder\stdplugs\stdscripts\ before to open max
 
----- USE:
----- Create your bitmap with aspect ratio 10:1. This must contain 10 square images side to side
----- Put it in diffuse channel of your material (that must be a VrayMtl, and must be ID#1 of a Multi/Sub-Object material)
----- Set bitmap cropping to W:0.1 H:1.0 (so only the first image is used)
----- Assign Multi/Sub-Object material to your object
----- Add "Face switcher DEV" modifier to your object
----- Click on "Pick Obj": bitmap name should appear in text box and thumbnails in numbered boxes (in this step the script create a lowres version of your bitmap to use in UI, same folder, same format, same name with suffix "_lowres")
----- Done! Now you can change your texture clicking on each thumbnail
----- If you move the time slider and change the texture, keyframes are created automatically (stepped)
 
----- PROBLEMS/BUGS:
----- Works only with multisubmat
----- Material with bitmap to switch must have ID#1
----- If you use a bitmap with alpha the small one created for UI is terrible (tried jpg, bmp, tiff, png... no way, but this is a max problem I think)
----- If you use it on more than one object with different materials (and bitmap of course) UI icons are always the same, even if texture name displayed is right
----- Something that I forgot for sure...
 
----- Probably there are errors and inaccuracies in this script, but this is one of my first tries and I know I miss the basics

EUREKA!

It works!
...with my stupid $ and vraymaterial, but it works!!

...
btn01.images = #(Fdir.text + "\lowres.jpg", undefined, 5, 1, 1, 1, 1)
btn02.images = #(Fdir.text + "\lowres.jpg", undefined, 5, 2, 1, 1, 1)
btn03.images = #(Fdir.text + "\lowres.jpg", undefined, 5, 3, 1, 1, 1)
btn04.images = #(Fdir.text + "\lowres.jpg", undefined, 5, 4, 1, 1, 1)
btn05.images = #(Fdir.text + "\lowres.jpg", undefined, 5, 5, 1, 1, 1)
...
on btn01 pressed do 
( $.material.texmap_diffuse.clipu = 0 )
on btn02 pressed do 
( $.material.texmap_diffuse.clipu = 0.2 )
on btn03 pressed do 
( $.material.texmap_diffuse.clipu = 0.4 )
on btn04 pressed do 
( $.material.texmap_diffuse.clipu = 0.6 )
on btn05 pressed do 
( $.material.texmap_diffuse.clipu = 0.8 )
...

Now I have to make it works with multimaterial and create keyframe automatically :)

Just try

with animate on (selection[1].material.texmap_diffuse.clipu = 0.4)

Perfect on vraymtl, but does not work on multisub material :(

I already post example how to manage nested VRayMtl inside any material (Multimaterial, Blend, VRayBlend, VRayLight etc.)

Yup,
and your advice have produced good results :)

on btn03 pressed do if selection.count != 0 do
 (
  if (mtl = selection[1].mat) != undefined do
   (
    mtl = getClassInstances VRayMtl target:mtl
     if mtl.count != 0 do 
      if isKindOf  (map = mtl[1].texmap_diffuse) bitmaptex do with animate on (map.clipu = 0.4)
   )
  )

Did I worked well?
:)

Yep. I will explain line by line

-- on button is pressed check first if selection exists
on btn03 pressed do if selection.count != 0 do 
(
	-- check if first item in selection have assigned material
	if (mtl = selection[1].mat) != undefined do
	(
		-- collect all VRayMtl instance in targeted object material
		-- this material can be multimaterial or any other that have VRayMtl nested inside
		-- in this case I overide "mtl" variable 
		-- at first this variable is selection material and then array of VRayMtl's
		mtl = getClassInstances VRayMtl target:mtl
		-- check if array is not empty
		if mtl.count != 0 do
			-- check if first material in array have texturemap in diffuse slot
			if isKindOf (map = mtl[1].texmap_diffuse) bitmaptex do with animate on (map.clipu = 0.4)
		   -- the rest you get it already ;)
	)
)

Wow, something I understood, something I missed :)

Last step is to set created keyframes to step with some

.inTangentType = #step
.outTangentType = #step

but all my attempts are failed.
