I can't get photorealistic rendering working

Hi, I have an un-networked NeXT running NeXTSTEP 3.0, and I can't seem to get the photoreal RenderMan server running. I discovered this by trying the beta copy of Perspective.app and trying to do a full rendering of an image. Apparently my machine got configured in such a way that the rpc.renderd daemon never executes at boot time. This was confirmed when I checked /private/adm/messages and found this note: Oct 1 14:52:38 localhost inetd[284]: renderd/rpc/udp: unknown service Running `rpcinfo -p' informed me that all the other inetd programs had been properly executed. My suspicion is that rpc.renderd is designed to be executed remotely and control processes running on several systems, and for some reason my computer thinks it is networked or something and thus doesn't find the rpc.renderd daemon. This is also possibly confirmed by this message in the N3DKit.rtf document in /NextLibrary/Documentation/NextDev/ReleaseNotes which states (near the end): > If you change the name of your host by editing /etc/hostconfig by > hand, the rendering machinery won't be able to find it. Local > rendering will not work. If you change the name of your host using > HostManager.app, then you have to further edit the netinfo database in > the . domain so your host has localhost as an alias. Now I haven't messed with hostconfig, but possibly I screwed up my netinfo database or something during my rather difficult upgrade process. Does anyone have some advice on how to make the rendering service work properly on my system? Thanks, Shane

First of all, this doesn't seem to be an uncommon problem. Within an hour of my original posting I had letters from two other people who also can't get photorealistic RenderMan running on their machines. One was networked, the other was not. Can someone help us? There must be several of us with this problem... Second, I was able to get the rpc.renderd running properly by starting NetInfoMangler and adding renderd as a rpc client and giving it the proper number (found in /etc/rpc - it's 200100002). Now when I run rpcinfo -p it tells me rpc.renderd is running as it should be. Unfortunately this doesn't change the basic fact that prman can't be referenced from Perspective.app (or RenderManager.app for that matter). What's going on??? Finally, I _can_ run prman by hand giving it a .rib file a input. It will generate (after some time) a file, ri.pic. Is this image file format documented somewhere? I have The RenderMan Companion, but it only makes passing reference to this file and doesn't give its format. Many thanks from myself and the others to anyone who can help us out! Shane
