Netrender usage: first read all requitremwents from the vray install guide. for the use of netrender with vray, there is some special manual installation method necesarry due to some current netrender specialities. MAC: Copy the Cinema4d.app in the netrender client and server folder (only the cinema4d.app itself, you need no full c4d install on the clients) download the installer from our support forum, (read the .pdf manual installation) copy the 3 vray .dylib files in the 3 OSX application packages ( use "show packe command,see pdf) into the "mac os" folder in the client ans server net installation, (make sure ALL 3 the cinema4d.app, the netrender.app and the server.app do have the .dylib files in their package in the macos folder) place the VrayBridge folder into c4d plugins folder. donnot rename anything of Vray or C4d. place the keyfile into netrender folders copy this adapted netrender folder to all your clients or do the same procedure on all net clients if you copy files to the application folder do this from the desktop make sure ALL c4d + vray parts and ALL lib files have full read and write permission(also the subfolders!) for your user and the admin on PC: install normal with install files into the netrender folder(copy the VrayBridge folder into plugins), place keyfile into netrender folders donnot rename anything of Vray or C4d. the message: "error set env!!!" is no real error, it comes through some needed tricks to make vray run in NET. so if this message occurs all is no problem. for mac and PC: for netrender usage the scenes must be setup in meter units(!) we do not recommend using mixed renderfram, it is possible though if you use a method that does not chache files, like the BR-LC render. ypu can also use the automatic save load Gi feature for mixed farms: 1) do a save as project, 2) activate "automatic GI load / save mode" in GI tab 3) render GI prechache files and save, set load file name for IR map(not lc thats already stored in IR) 4) render via net NEtrender(also mixed farms) if you want to use mixed farms with cached files, we you can also use a professional rendermanager software, that translates mac to pc network paths and vice versa. on 1.2.5.1 please also add the keyfile to your netclient installation
