Is there any way (Mel/Python...) to convert a AiStandardSurface material to a Lambert/Phong/Blinn and still mantain material color properties?
Because i have a lot of objects with arnold materials (The project im working on was supposed to be a short) but now they also want a very simple unity project to show the models(Most of them can be flat colors without textures, they just need to see the model itself) and if i export an fbx with arnold materials, it does export the materials but when i do import them in unnity, the flat color is grey, instead of the ones the aiStandardSurface has
Just in case anyone was wondering how.
This is how a friend (Github: @PRZurro) managed to convert just the BaseColor of a aiStandardSurfaceLegacy Shader to the Color of Legacy Shader
string $newMaterialType = "blinn";
string $newMaterial = `createNode $newMaterialType`;
string $oldMaterials[] = `ls -type "aiStandardSurface"`;
string $oldMaterialsAttr[] = `listAttr -visible -settable -scalar $oldMaterials`;
string $newMaterialAttr[] = `listAttr -visible -settable -scalar $newMaterial`;
string $ca[] = stringArrayRemove($newMaterialAttr, $oldMaterialsAttr);
$ca = stringArrayRemove($ca, $oldMaterialsAttr);
delete $newMaterial;
string $a; string $b; string $m; float $v; string $cl[];
for ($m in $oldMaterials)
{
$newMaterial = `createNode $newMaterialType`;
$cl = `listConnections -destination true -plugs true -source false -type shadingEngine $m`;
connectAttr -f ($newMaterial + ".outColor") ($cl);
for ($a in $ca)
{
$v = `getAttr ($m + "." + $a)`;
catchQuiet(`setAttr ($newMaterial + "." + $a) $v`);
}
float $colorR = `getAttr($m + ".baseColorR")` ;
catchQuiet(`setAttr ($newMaterial + ".colorR") $colorR`);
float $colorG = `getAttr($m + ".baseColorG")` ;
catchQuiet(`setAttr ($newMaterial + ".colorG") $colorG`);
float $colorB = `getAttr($m + ".baseColorB")` ;
catchQuiet(`setAttr ($newMaterial + ".colorB") $colorB`);
delete $m;
}
I've used this script:
//change all phong Materials to aiStandard Material
// If you need to change another Material, simple change `ls -type "phong"`
{
string $newMaterialType = "aiStandard";
string $nm = `createNode $newMaterialType`;
string $ms[] = `ls -type "blinn"`;
string $pa[] = `listAttr -visible -settable -scalar $ms`;
string $nma[] = `listAttr -visible -settable -scalar $nm`;
string $ca[] = stringArrayRemove($nma, $pa);
$ca = stringArrayRemove($ca, $pa);
delete $nm;
string $a; string $m; float $v; string $cl[];
for ($m in $ms)
{
$nm = `createNode $newMaterialType`;
$cl = `listConnections -destination true -plugs true -source false -type shadingEngine $m`;
connectAttr -f ($nm + ".outColor") ($cl);
for ($a in $ca)
{
$v = `getAttr ($m + "." + $a)`;
catchQuiet(`setAttr ($nm + "." + $a) $v`);
}
delete $m;
}
}
to convert a blinn to arnold, and it does work, so i tried the other way:
//change all phong Materials to aiStandard Material
// If you need to change another Material, simple change `ls -type "phong"`
{
string $newMaterialType = "blinn";
string $nm = `createNode $newMaterialType`;
string $ms[] = `ls -type "aiStandard"`;
string $pa[] = `listAttr -visible -settable -scalar $ms`;
string $nma[] = `listAttr -visible -settable -scalar $nm`;
string $ca[] = stringArrayRemove($nma, $pa);
$ca = stringArrayRemove($ca, $pa);
delete $nm;
string $a; string $m; float $v; string $cl[];
for ($m in $ms)
{
$nm = `createNode $newMaterialType`;
$cl = `listConnections -destination true -plugs true -source false -type shadingEngine $m`;
connectAttr -f ($nm + ".outColor") ($cl);
for ($a in $ca)
{
$v = `getAttr ($m + "." + $a)`;
catchQuiet(`setAttr ($nm + "." + $a) $v`);
}
delete $m;
}
}
I've also tried "aiStandardSurface" instead of "aiStandard"
But this doesnt work...
i get this error:
// Error: line 18: The destination attribute '' cannot be found. //
