Hello,
I am trying to output materials from 3dsmax and noticed that it is not easy.
First of all, if I execute maxscript command
showProperties $Box001.material
and Standard material is assigned to Box001 object, I will receive a list of ALL parameters of Standard material. How can I get the same list using 3dsmax SDK?
OK, there is Animatable, IParamBlock and IParamBlock2 classes but list of parameters received with these classes is not full. To output parameters I used following code:
void LogParamBlockProp(IParamBlock *pblock, int shift)
{
LogOutput("This is a ParamBlock with parameters:", shift);
LogOutput("{", shift);
int numParam = pblock->NumParams();
for(int i=0;i<numParam;i++)
{
const char* type;
switch(pblock->GetParameterType(i))
{
case TYPE_FLOAT:
type = "type_float";
break;
case TYPE_INT:
type = "type_int";
break;
case TYPE_BOOL:
type = "type_bool";
break;
case TYPE_POINT3:
type = "type_point3";
break;
case TYPE_RGBA:
type = "type_rgba";
break;
default:
type = "Unknown";
break;
}
{
char buffer[STRING_BUFFER_SIZE];
sprintf_s(
buffer,
"Parameter %d: %s",
i,
type);
LogOutput(buffer, shift+1);
}
}
LogOutput("}", shift);
}
void LogParamBlockProp(IParamBlock2 *pblock, int shift)
{
ParamBlockDesc2 *desc = pblock->GetDesc();
LogOutput("This is a IParamBlock2 with parameters:", shift);
LogOutput("{", shift);
int numParam = desc->Count();
for(int i=0;i<numParam;i++)
{
const char* type;
switch(desc->paramdefs[i].type)
{
case TYPE_FLOAT:
type = "type_float";
break;
case TYPE_WORLD:
type = "type_world";
break;
case TYPE_INT:
type = "type_int";
break;
case TYPE_BOOL:
type = "type_bool";
break;
case TYPE_POINT3:
type = "type_point3";
break;
case TYPE_COLOR:
type = "type_color";
break;
case TYPE_RGBA:
type = "type_rgba";
break;
case TYPE_PCNT_FRAC:
type = "type_pcnt_frac";
break;
case TYPE_BITMAP:
type = "type_bitmap";
break;
case TYPE_FRGBA:
type = "type_frgba";
break;
case TYPE_TEXMAP:
type = "type_texmap";
break;
default:
type = "Unknown";
break;
}
{
char buffer[STRING_BUFFER_SIZE];
sprintf_s(
buffer,
"Parameter %d: %s %s",
desc->paramdefs[i].ID,
desc->paramdefs[i].int_name,
type);
LogOutput(buffer, shift+1);
}
}
LogOutput("}", shift);
}
void LogObjectProp(Animatable *sub, int shift)
{
if( sub->IsSubClassOf(PARAMBLOCK2CLASSID) )
{
LogParamBlockProp((IParamBlock2 *)sub, shift);
}
if( sub->IsSubClassOf(PARAMBLOCKCLASSID) )
{
LogParamBlockProp((IParamBlock *)sub, shift);
}
int numSubs = sub->NumSubs();
if(numSubs == 0)
{
return;
}
{
char buffer[STRING_BUFFER_SIZE];
sprintf_s(
buffer,
"This Animatable contains %d subanimatabless:",
numSubs );
LogOutput(buffer, shift);
}
LogOutput("{", shift);
Animatable *subsub;
for(int i=0;i<numSubs;i++)
{
{
char buffer[STRING_BUFFER_SIZE];
sprintf_s(
buffer,
"%d) Name: %s",
i,
sub->SubAnimName(i) );
LogOutput(buffer, shift+1);
}
subsub = sub->SubAnim(i);
if(subsub)
{
showObjectProp(subsub, shift+1);
}
}
LogOutput("}", shift);
}
This code produces following output:

How can I get all the parameters of a material?

for o in (GetPropNames $.material) do

Mar 16, 2012 12:05 am
But this is maxscript. I need to get the same list as showProperties but using 3dsmax SDK on C++
Mar 16, 2012 12:05 am
can’t you get this info directly from from StdMat2, StdMat, Mtl class hierarchy ?
from an INode something like this will get you access
Mtl* nodeMtl = node->GetMtl ();
StdMat2* stdMat = dynamic_cast<StdMat2*>(nodeMtl );
if(stdMat)
{
.....
Mar 16, 2012 12:05 am
I am sorry but no I can’t. Because I need to output not only standard material, I need to output all parameters of any material.
Mar 16, 2012 12:05 am
there a property enumeration system , IGameProperty, in the IGame export wrapper you could look at.
Mar 16, 2012 12:05 am
IGameProperty is a wrapper around the standard 3ds Max ParamBlock and ParamBlock2. I’m already working with ParamBlock and ParamBlock2. You can see the code I listed in the first massage.
The problem that the numbers of parameters I received with ParamBlock/ParamBlock2 system is much less than I received with showProperties. Where can I find ALL the parameters?
Mar 16, 2012 12:05 am
looks to me as if you are not sending the right/complete paramblock to your enumerator`or the enumerator is getting all the params.
one of the ParamBlockDesc2 for stdmtl2
static ParamBlockDesc2 std2_shader_blk (
std2_shader, _T("shaderParameters"), 0, &stdmtl2CD, P_AUTO_CONSTRUCT + P_AUTO_UI, SHADER_PB_REF,
//rollout
IDD_DMTL_SHADER4, IDS_KE_SHADER, 0, 0, &shaderDlgProc,
// params
std2_shader_type, _T("shaderType"), TYPE_INT, 0, IDS_JW_SHADERTYPE,
p_default, 3,
p_ui, TYPE_INTLISTBOX, IDC_SHADER, 0,
p_accessor, &shaderPBAccessor,
end,
std2_wire, _T("wire"), TYPE_BOOL, 0, IDS_DS_WIREFRAME,
p_default, FALSE,
p_ui, TYPE_SINGLECHEKBOX, IDC_WIRE,
p_accessor, &shaderPBAccessor,
end,
std2_two_sided, _T("twoSided"), TYPE_BOOL, 0, IDS_JW_TWOSIDED,
p_default, FALSE,
p_ui, TYPE_SINGLECHEKBOX, IDC_2SIDE,
p_accessor, &shaderPBAccessor,
end,
std2_face_map, _T("faceMap"), TYPE_BOOL, 0, IDS_JW_FACEMAP,
p_default, FALSE,
p_ui, TYPE_SINGLECHEKBOX, IDC_FACE_MAP,
p_accessor, &shaderPBAccessor,
end,
std2_faceted, _T("faceted"), TYPE_BOOL, 0, IDS_KE_FACETED,
p_default, FALSE,
p_ui, TYPE_SINGLECHEKBOX, IDC_FACETED,
p_accessor, &shaderPBAccessor,
end,
std2_shader_by_name, _T("shaderByName"), TYPE_STRING, 0, IDS_JW_SHADERBYNAME,
p_accessor, &shaderPBAccessor,
end,
end
);
seems to contain params not in your sdk output (from stdmtl2.cpp in maxsdk\samples\materials
Mar 16, 2012 12:05 am
Yes, I has seen stdmtl2.cpp. And I’ve got all the parameters that are in stdmtl.cpp. But there are the last 16 parameters of showProperties output of Standard material:
.noExposureControl : boolean
.exposureControlInvertSelfIllum : boolean
.exposureControlInvertReflection : boolean
.exposureControlInvertRefraction : boolean
.ambient (Ambient_Color) : RGB color
.diffuse (Diffuse_Color) : RGB color
.specular (Specular_Color) : RGB color
.adTextureLock (Ambient_Diffuse_Texture_Lock) : boolean
.adLock (Ambient_Diffuse_Lock) : boolean
.dsLock (Diffuse_Specular_Lock) : boolean
.useSelfIllumColor (Use_Self_Illum_Color) : boolean
.selfIllumAmount (Self_Illumination) : percent
.selfIllumColor (Self_Illum_Color) : RGB color
.specularLevel (Specular_Level) : percent
.glossiness : percent
.soften : float
What is it? I tried to search any of these parameters in stdmtl2.cpp and there is no text coincidence. It seems to me these parameters are parameters of Shader *pShader; (string 191 of stdmtl2.h) But pShader belongs only to class StdMtl2. How to get pShader using max SDK from a Mtl object? Or how to get ALL of these parameters?
Mar 16, 2012 12:05 am
In Standard material, each “Shader” such as Blinn/Phong/Anisotropic is a seperate plugin.
Mar 16, 2012 12:05 am
OK, I found it.
It is possible to get all the parameters with ReferenceMaker::GetReference() method.
Mar 16, 2012 12:05 am
however, if you asked a question on this forum but got an answer yourself, please show your solution. thanx
Mar 16, 2012 12:05 am
Actually ReferenceMaker::GetReference() is the solution. The following code will output all the parameters of the material.
