I’m creating a cave in Blender. However, I think that the size will be too large for the pc to render everything including materials, textures etc. It would be ideal to render the model in different parts to help speed up rendering.
Also, it would be useful to split the whole thing up anyway, so that it is not a humongous model of the cave (it has various passages, fissures and restrictions)!
How can I split the model, so that it renders all the parts separately… but the rendered model looks seamless??
My goal is that in the final render, I would like to have a camera attached to a light, flying through the cave model. But if the model is split up into different parts… how would this be possible??
One thing that might seriously help you here is: “a video editor.” If you were to envision – say – a “drone video of a real [outdoor scene],” it would probably not consist of “a single, continous shot.” Because that, quite frankly, could become tedious and boring. Instead, the footage (even if originally taken “continously”) is edited into a series of shorter segments with visual continuity.
To put it another way: you’re not just depicting an area. You’re telling a story. “Something interesting down there?” #CUT TO# an ECU (extreme close-up) of it, then cut back to the same or a later part of the original “fly-by.” Things like that.
This, then, gives you “a way out.” You don’t have to render, or even to model(!), “everything at once.” Figure out what you want the shot-sequence (or POV’s) to be, render them individually and then cut them together. As long as you first establish to the viewer “where” he is and “where” he’s going, you can then use techniques like “jump cuts” to then keep the rhythm and pace that you want. The renders are “the raw material” for editing, which is the process that actually “makes the show.”
You can begin with extremely rough geometry (to scale …) that represents “the cave.” Then, place cameras on it and “just start shooting things.” Then, look at that footage in your editor. Begin even then to “cut it.” What story do you want to tell the audience about that cave?
However… I’m not really interested in a story telling some of movie etc.
The cave fly by is to be presented as part of a caving project. Just want the camera to fly by all the areas in one take.
But how do I achieve this?? Using Blender’s compositing? What are the steps?? Should I look into compositing by learning tutorials and take it from there? Or perhaps other software?? Or other techniques??
Sow when you yourself mention the first sentece… then do some splitting in the planning phase… maybe
main cave
“floor” to smaller part
“secret” room
whatever
…and this answers the second sentence. When you are in the planning phase you might also start wit some blockout and use this as some level of detail… maybe also some more detailed part before you got into high detail and use this for your
planning of the flight sequence
and so later know which part are used for every subsequence of the animation and simply use only that parts which are needed ?
In this way the cave building and flight path planing might have some synergy effects.
