one thing that helps alot is removing any geometry NOT visible from the view you are rendering...

try this:

in your render view, do command SelVisible >

then command Invert >

then command Hide

this will hide all the geometry that isn't visible from your render view and reduce the amount of processing that needs to be done.

is this foolproof? No. some items may not be selected that should, and some will be selected that shouldn't, but it's a huge help to take the load off the system. make any adjustments to individual items as necessary.

good luck, let us know if it works for you.

Stu, 

thanks for replying i figure out what the problem was i replied to Charley's post with the solution if it interests you. It had to do with loading textures. Anyhow i do appreciate your suggestion and who knows maybe later in the future i may need to use it. 

Thanks,

Sal

Hey Sal !

Hope this finds you well.

 

Sorry, no answers in this reply, but your input will help me. I'm thinking about VRAY as an alternative renderer to Flamingo nxt. I need a quick-shot raytrace renderer for my animations (BO-1/32 is an EXCELLENT product ! ) . I plan to run RH-4 on a NEW -XP/32 Single-core Pentium 3.4Ghz with RAM maxed at 4GB because of the -XP/32 limit, which will still deliver ~3Gb to my RH because -XP will put O-S and Video stuff in the upper last Gb even tho the docs all say no. Any 32-Bit is the only stable platform I've found that effectively combines RH-4 with BONGO as a plugin. RH-5/64+BO-2/64 is good, but RH-5 on -64Bit drops material assignments from objects, and a material with a transparency drops the material on the item behind the transparency (except for the portion that might peek out from behind).

 

SO-

 

Are you running your RH as -4 or as -5 ? Remember, -4 is 32-Bit only and even with 12Gb RAM your RH-4 will only see ~2+, as Win-7's allocation of RAM in a 32-Bit session (for the RH-4 + ANY plugins including VRAY) STARTS seeing only 3Gb  (NOT about 3-1/2 Gb as in -XP). Then you load O-S and anything else the O-S "thinks" you'll need to communicate with peripherals, other services, etc. THEN you load RH-4, THEN it loads VRAY AND every other automatically loaded plugin including things like 3D Sollid Printer plugins and Internet Browser link plugins. VERY LITTLE is left over for you to use in RHINO-4.

 

OR-

 

Are you attempting to run RH-5/64 with VRAY plugin ? If so, you may be dealing with an actual stability issue.

 

Either way is problematic. I'd check with the folks at McNeel's Techical support site. They try VERY hard to help work these things out, and if they can help you they'll do their best ! Of course, removing unnecessary items in a render scene may help, but as ANYTHING in any of my scenes is ONLY there because its necessary, I can't really relate to that approach to solving the problem. BUT - DEFINITELY try that, it may help. Let us know here if it did ?

 

Summary - Are you running RH-4/32 or RH-5-64 ?

 

GOOD LUCK ! and let us know how it went ?

 

Thanks-

 

Charley.

Charley, thanks for the reply i am actually running RH 4 with 64 bit. And your right i don't get much out of my 12G of ram...but with that said i finally found out what the problem was.

It was my textures,  It took me a while to figure it out, but I had purchased some textures and it came with a series of maps; diffuse map, bump map, and this specular map. Me not having much experience, was basically just using trail and error until i would get the results I wanted.

My error was not loading the bump map in its proper location, i tried it under displacement and then for the specular map i loaded it under the reflection option. So i just changed the bitmap from displacement to bump and just eliminated the specular map. Materials look great with just the diffuse and bump map, no need for specular map in my case. And it rendered with no problem, pretty fast too.

But if your familiar with using the specular map and have had great results please let me know. I would rather know how to use it then not know how to use it, even if it add a ridiculous amount of rendering time.

Thank you,

Sal
