nd = findNode("chrome")
fds = nd.getMaterial().fields()
fds.setString("chromeType","highlyReflective")

nd = findNode("paint")
fds = nd.getMaterial().fields()
fds.setString("paintType","2-coat")

but script does not work with error:

vrFieldAccess::setField: Couldn't find field 'chromeType'

vrFieldAccess::setField: Couldn't find field 'paintType'

There is no real documentation for all the fields of each material. However, you can use the node editor to figure out which field to set and additionally the type of the field (tooltip when the mouse is over the value in the node editor). In your case:

# Chrome type
mat = findMaterial("Chrome")
mat.fields().setInt32("metalType",4)

# Paint type
mat = findMaterial("Paint")
mat.fields().setInt32("paintType",1)

Cheers,

Thanks a lot,

and I tried more to set chome "use roughness" to true with script below:

# chrome matte, set useRoughness ?
mat = findMaterial("chrome-matte")
mat.fields().setBool("useRoughness",True)

ends with error

error vrFieldAccess::setField: Couldn't find field 'useRoughness'

need help for this issue.

and if there is some documentation of python api on the things like these, that would be much better...

Hi,

as Marcus has written, instead of documentation we have the Node Editor (a module in the GUI, Scene > Node Editor) where you can see all fields of a selected object. For materials, drag & drop them from the Material Editor into the module.

In this case, it is "isRough".

Kind regards
