Material > Bitmaps

[blakestone]

I am listing all the materials in my scene with ==> sceneMaterials <== and when I access the .maps it shows the following:

#(undefined, Map #3:Bitmap, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined,
undefined, undefined, undefined, undefined, undefined, ...)

which I am pretty sure is all the Bitmap channels in the Standard Material rollout, however I am not sure how to find out what is what i.e Diffuse, Specular, Bump, Displace, Opacity etc.

It's all in the help 😛

Locate the "StandardMaterial : Material" topic, scroll to the bottom of the page. Easiest way is to go the Index > Material > Types (on the next line) > Standard (on the resulting page).

Note. The array elements are not consistent - they differ by the specific shader (Metal, Blinn, Phong etc) making it difficult to iterate over them. You might be better off getting them individually (DiffuseMap, OpacityMap etc) which are consistent regardless of array element, but of course not all maps exist in all the shaders.

Thanks for the quick response... I was looking at this but before going ahead wanted to check if there was a quicker/easier way to check this via the .maps array

Not that I know of - doesn't mean there isn't one, just that I don't know it.

I try this only consider standard material but you can expand this

for o in objects where o.material != undefined do
(
   case (classof o.material) of
   (
      (standardmaterial): (
         if (pcnt = (getPropNames $).count) != 0 do
         (
             for i = 1 to pcnt where mod i 2 == 0 do 
             (
                if i == 2 do format "%\n" (">>>" + o.material as string)
                format "%\n" ((getPropNames o))
             )
         )
      )
      --(): ()
   )
)
