Camera Mapping problem

[darkline]

Camera mapping in octane works ok if you simply want to match a static background plate. But a lot of the time camera mapping is used to create a 3D scene where the camera moves through the mapped planes.

examples here :

this is something you can do in almost all renderers in 3dsmax (even in after effects and apple motion). Currently the camera map function in Octane is always 'live' hence there is no way to 'lock' the projection to the geometry in the scene. I simply want to create a few walls, floor and have octane project the geometry onto them so I can then move the camera through it. As far as I caa see this already works in other apps like cinema 4D with octane.

I wouldn't think this was too hard to achieve as octane is doing half the work already. It projects an image perfectly onto the geometry, just currently recaculcates every time the camera moves. Perhaps we could have a tickbox that says 'capture projection' or something similar, so we can choose to lock it when it's right.

Hi darkline,
I think automatic camera mapping is in the to-do list of developers.
There is a workaround:

but certainly it is not comfortable animating the camera.

Thanks Paride

yes animating the camera is the most important thing

Hi darkline,
sorry, I may have misread your question, you can use the 3dsMax camera map binding modifier.

Hi Paride

Can you show an example of how this is done?

HI darkline,
This is a camera mapping workflow example in 3dsmax:

Hi Paride,

This example shows camera mapping with normal renderer. In octane we have to use camera map checkbox, are you saying this works with the example above and you can create a moving camera through a camera mapped environment?

I darkline,
I think so, I do not have a test scene to sharing now, but I remember having tried with Octane render and I remember it worked.
You have to use a 3dsmax camera (I remember that way).

as stated here, you need to use camera map per pixel in order to get it right. the mapping looks all wrong in the viewport and was limitation of old camera map modifier

also take a look here, cinema 4D can do this fine, I commented about it before to Azen

jump to about post 3 on this thread, not sure if anything has come of this?

Hi darkline,
An integrated camera mapping, like in C4D, is not done yet, I will check if in to do list and I will ask for that.
3dsMax camera mapping seems to work; I made a quick rough test, it looks okay, take a look at it.
