Would streaming be a solution to memory cap?

[Krisonrik]

I remember reading out ID soft making their game engine capable of utilizing 10GB of texture through their streaming process. I am no programmer, just a thought and am curious as to whether it could be a solution to Octane's memory limitations. I mean could there be a way to do bucket rendering with Octane and then after the bucket size finish rendering, Octane can stream the texture that is needed for the next bucket and wipe the current texture memory usage. It would be so cool if we can get around the memory problem without waiting for few years of hardware development time. Still, I can't imagine 6GB - 12GB of VRAM being cheap.

Hi, an unbiased GI renderer needs to have all information present at all times, a ray can bounce on anything anywhere, so it's not possible unfortunately.
We're optimizing octane and with the new procedural materials you will be able to do far more complex stuff.

Yeah I guess once we have a full library of procedural texture, things can get much easier. Is it possible to have things like composite map in Octane? Like what Max has. I'm not a bit Max fan, since I'm more of a Maya lover, but I do like the composite map in Max, makes life so much easier without the need to go back to Photoshop and do all the texture works.

what's a composite map ?

multi layer map, like in photoshop

But this will lead to massive memory consumption no? better do this in max and export map in one single texture rather than eat your ram in octane..

you can do this with the mix texture.
but if you plan to mix 10 unique textures and don't reuse those on other materials it's better to prebake it first indeed.

I might got it wrong but what I think he means is mixing two materials, not textures, like a mix for materials, say, you got concrete, and wet concrete materials, then you mix with a puddle map, but each material is its own and could be used separately.

a mix material will be for 2.3

Composite map is useful when one ,for some reason, want to use ,for example, 2 different maps for same bump map channel, or 2 different maps for mask in mix map/material etc. It can be quite handy when creating complex shaders. Advantage is that you can create new maps from existing ones comping them and saving some RAM that way. At some point it would be nice if Octane could support this feature.

you can use the mix material to mix textures together in 2.2.
to mix materials you will have to wait until 2.3.
