There is a request to edit the VRMat file created in the past by my customer.
In V-RayNext, VRMat Editor is no longer provided.
What is the answer of ChaosGroup?
What I can think of
>> Re-install OLD V-Ray 3.x that can use VRMatEditor.
Can not, customers will use max2018 and 2019.
Also, you should not force you to reinstall OLD V-Ray for reasons to use VRMatEditor.
>> Install V-RayRevit, V-RaySketchUp, V-RayRhino
Customers do not own those licenses. Only one month can be used in the evaluation version.
