warrning about standardmaterial and custommaterial developing

hi @Deltakosh

i saw some main uniform   ( like vDiffuseUV ) is changed in standardMaterial

this is why i want design custommaterial pattern inside of standard material because when we change standard material we just change .ts version 

and not change  shader version all material Library use own shader but custom material supposed to use base shader 

i have solution for fix that but i need change that in standard material else i most make fixed version of standard material for V3 and make custom material from this

so what is your recommend about that  ?

sol 1 :  append custom material shader parts to main shader Version?

sol 2 : make fixed version of standard material and inherited from them for make custom material [ in this case standard material changes not set by each  changes ]
