RPC load times during rendering problem

[thomaschristensen]

Hi everyone,

 

First of all I'm new here and did a search, couldn't find any similar topics so I apologies if this has been discussed before.

 

To the problem:

So I am outputting a fairly long animation with an rpc pass for people and I am having problems controlling render times while rendering rpc. As no matter resolution or quality settings (scanline or vray) max wants to / needs to load all the rpc files and setup the render every frame, which takes forever! So say the actual rendering of the frame takes 5 secs, the entire frame can take 40, and there doesn't seem to be anyway to get adjust those 35 secs at the start?

 

My question is, does anyone have any tips or experience optimizing rpc for quick preview rendering?

 

Thanks in advance.

RPC's are different from everything else in your scene, there not made of polygons just pictures of things that have to be reloaded every time the camera moves. There's nothing you can do to speed up this process that's just how they work.

Unfortunately also my conclusion... ah well was worth the try. Real problem happens when its combined with a really heavy scene, things just take forever.

people still use RPC? aren't the people super dated now?

Super super SUPER dated indeed... how ever there is no alternative for a quick and effective solution. The 2.5D'ness of RPC is still good enough and a lot faster than any of the full 3D HD high poly models when you need 50-150 people static people.

 

If you got other ideas please let me know I would give my right arm for a replacement for RPC

 

EDIT: something to note too, is that I think the biggest reason for my delay here is the actual scene geometry, and I wonder if I can speed the loading of that up every frame by proxy'ing the whole lot? I haven't tested it as I can't for preview purposes (client being difficult). But does anyone know if vray for instance loads in proxy geometry faster than "standard" ?

Proxies only really help with things like trees, cars etc that take up a lot of memory especially if there are many instances of them. They are constantly loaded/unloaded during the render process. So it may not be that efficient to proxie the whole scene, but certainly for some of it.

 

As for the RPC's, the other "Old School" method is to use Billboard people. They have the same 2.5D issues of RPC's but with out the need to reload the textures for each frame. They do take a while to set up though.
