I am using Vray V3 and cannot save the alpha channel. I go through the save rgb no problem, then do exactly the same to save alpha channel but re-name the file, the save window closes but in the folder there is no alpha channel file? I have tried saving as png, jpeg and tiff, still the same, any ideas?
A colleague has just found the little arrow on the save button which allows you to save a single channel, all channels separately, or all channels single file.
Hi,
This is a known issue and our developers are currently working on a solution, which should be implemented in an upcoming hotfix update.
In the meantime, as a temporary workaround, you could also use the ‘Save Image’ option (Asset Editor > Settings > Render Output) prior to initiating a render process. When the render is complete, the produced image will be automatically saved along with all render channels.
Hello,
For an alternative workaround, please see the following thread:
