I try to extend the DX9 Material.

The Idea ist to get an UI with Buttons and Fields for customizing a shader.

Works so far (Refraction etc. works fine with delegate ...), but i got Problems with delegating the Bitmaps.

Somebody with experience in delegating bitmaps in an extending PlugIn ???

Ok the delegating of the bitmaps seems to work ...
but the scene has a wrong lighting. so i hope to fix it

the problem is the shader wants a float4 light direction, max originaly set light dir by index (all lights in the scene enumerated).

Are you making your material for manipulating shader parameters?

If you define your .fx file with proper semantics, the DX9 shader will expose those controls in the rollout. That is the beauty of it. If you can find it, try to get notes or slides from some of the GDC talks this year. The one by Neil Hazzard and Adam Pletcher of Volition talked about this particular subject.

I work right next to Adam, so if you have any questions, I can probably answer them.

You can only have 1 light in Max affecting DX9 materials. We have noticed that lighting seems to get out of sync with the shader, so we wrote a tool that loops through the shader materials and forces a update of the textures.

If you can give more specifics to your problem, I can probably help more.

The bitmap delegation works fine now. i had a problem with delegate them in the parameters main block with on set val (because i had problems to set a ui element for the bitmaps that works correctly). Now i delegate it in Rollout Params in a on pressed button block directly. The lighting is ok, only problem is if i add lights, i don't know how to update the material, so i can choose the new light for lighting.
before the parameters main block i do


objectsarray = lights
aLights = #()
aLights[1] = "DefaultLight"
j=2
for oItem in objectsarray do (
if (superClassOf oItem == Light) do (
aLights[j] = oItem.name
j = j +1
)
)

The array is complete but i don't know how to update the light dropdownlist.
if i change the active material in the material editor two times, i got the new added lights in my dropdownlist.

What we do is loop through the scene materials and force the .delegate.lightpos of each material to point to the selected light in the scene. Try doing that and see if it helps.

Thanks i will try it soon as possible ...

Holy shit, i got a problem: i cannot load scenes containing the new material ... i hope i can fix it ... . max crashes with "An Error occured .. blah blah message ..." possible a mem leak (the viewport borders are drawed, the scene not. Then a few seconds nothing and then the crash ...) mhm i will see ...

hi,

Could You show how did You do bitmap delegate?
I'v created very similar material,and and exporter (Panda exporter) exports texture filename not correctly if slot is empty.
