[Closed] Possible to remove extended parameter.??

No one can answer this? I don’t need the full answer just if it’s fesable…

Bobo maybe?

probably the extended parameter is some custom attribute. if you know this attribute definition or index you can delete it using custAttributes.delete (see mxs help – > Custom Attributes Management Functions)

if you don’t need any custom attribute you can use:

 while <node>.custAttributes.count > 0 do deleteItem <node>.custAttributes  1
 

Well, this is the original script that have been used on all our material libraries…
So if I have a machine that don’t have this extended material the material doesn’t load cause missing plugin… So how I can convert a material back to basic by removing my costum extended parameters. This was for managing VRay receive and generate GI by material and not by objects.

plugin material VRayUrbanimage
name:“VRay Urbanimage”
classID:#(0x7ca77987, 0x462dc734)
extends:VRayMTL
replaceUI:false
version:1
(
parameters main rollout:params
(
generateGI type:#float ui:generateGI default:1.00
receiveGI type:#float ui:receiveGI default:1.00
)

 rollout params "Extended Urbanimage Attributes" 
 ( 
     spinner generateGI "Generate GI" fieldwidth:50 range:[0.00,100.00,1.00] scale:0.01 align:#center across:2
     spinner receiveGI  "Receive  GI" fieldwidth:50 range:[0.00,100.00,1.00] scale:0.01

     on generateGI changed value do
     (
         objList = #()
         
         for x in $* do
         (
             if x.material == meditmaterials[medit.GetActiveMtlSlot()] do
             (
                 try(
                         setUserProp x "VRay_GI_GenerateMultipier" x.material.generateGI
                         setUserProp x "VRay_GI_Multipier" x.material.receiveGI
                     )
             catch()
             )
         )
     )

     on receiveGI changed value do
     (
         objList = #()
         
         for x in $* do
         (
             if x.material == meditmaterials[medit.GetActiveMtlSlot()] do
             (
                 try(
                         setUserProp x "VRay_GI_GenerateMultipier" x.material.generateGI
                         setUserProp x "VRay_GI_Multipier" x.material.receiveGI
                     )
             catch()
             )
         )
     )
 ) 

)

Your logic is flawed, the problem is the scripted plugin not the parameters. As long as the plugin (classID:#(0x7ca77987, 0x462dc734)) is referenced in the scenes then you will get the missing plugin warnings. Deleting the extended parameters won’t do anything, you must delete all reference to the plugin/material in the scene to make it no longer a part of the scene. So you will need to replace every VrayUrbanimage reference to make it go away.

The easier solution is placing plugins like that on a shared network drive that your plugin.ini points to.

So the only way to remove it will be to create a script that loop all objects that have the VRayUrbanimage Materials and copy each parameter to a new VRay Standard material then assign that new material back to the object. ? Can I create a array of all the VrayUrbanimage material in my library?

thanks a lot guys!
Will give this a try.
