I have installed Vray for rhino 3.0 but when i turn on Rhino it load everything except this RCM ( it says--- Failed to read registryfor RCM Status--- RCM mapping channel will be unavaible ).
This give me many problems with rendering…does any of you know what to do???
Check the McNeel wiki for RDK updates. There should be a download that will solve the problem. RCM got changed to RDK a few months back, so thats why you need to search for RDK
I think some other users have had this problem after installing VfR4 - i think the RDK installer that our VfR4 installs may remove the older RCM stuff. Perhaps if you repair your VfR3 install it will resolve that issue? Also - when we get the VfR3 update out this issue should no longer trouble you, as our VfR3 will be using the new RDK as well.
