int | forcebrdf |
| | Used to render materials with sharp sparks, a procedural map with relative size this param is used to feed the RR sampling.
|
| |
|
float | free4 |
| | the material thumnail relative offset - this is kind of a hack, using the place of an old obsolete parameter to get fast access to the material thumbnail

|
float | indmul |
| | When flakes is nonzero (spark mode) this parameter specifies to not scramble the uv coordinates.
|
| |
|
int | keepflakesuv |

|
| |
|
float | lfsizecm |
| | value used to control the function converting translucency to transparency
|
| |
|
float | orggls |
| | Clear coat noise-like bump amount (there is separate hmap bump)
|
| |
|
float | orgglvar |
| | the clear coat glossiness the inverse angle deviation width (60 is one degree), since 20.04.21 this is real preset, but the old materials use specbell

| |
|
float | thickness |
| |
|
int | thumbpos |
| | the clearcoat glossiness variation (0-none 1-the shallow anglesare glossy), since 20.04.21 this is real preset, but the old materials use scratchdens
|
| |
|
float | topvLs_A |
| | Used mostly with top view fabrics, modifies the rendering of the inclined views making them blurred and fuzzy.
|
| |
|
float | topvLs_B |
| | Used in top view materials to control the light direction correction.
|

|
| |
|
int | triplanar |
| | The sample thickness in mm, used to introduce alpha/translucency correction of thick materials.

A structure containing some parameter values considered optimal for the rendering of the material for example the ccior, you can add clear coat to any material by the UI, but the car paints should have ior by default, so in this structure we keep the values that must be set when the material is just created. Not all the members are used, this is because the structure is stored in the file as single block and removing a member will destroy the compatibility. Not all the members have corresponding member in the VRScansPrm, this is because it's considered pointless to make them tweakable, for example the flakes member is used directly, it's not tweakable.
