Bake camera projection onto object? Tweet

[JackMcRip]

I performed camera tracking in Blender - Octane Subscription License.
The camera moves forward in a slight arc.
I want to continue this movement for 3 seconds.
For this, I want to bake the last frame of the film onto 3D objects.

I can only find tutorials on how to project the camera image onto objects and cast the shadows of new 3D objects onto the film image.
However, I can't find a tutorial that shows how to use the camera bake function of Octane, or the bake node, to bake the projected image onto the object permanently.

Can someone help me with a link or a tip?

with the bake node I get no output. Only a black image.
with the camera bake I get the result that you can see in the attached image.

I have no idea, how I can get the rendered film image in a texture image file for the plane.

I found a link, how bake in octane standalone.
But the link to the octane manual is dead:

There's an extra underscore in the address. Try:

The search works fine.

thanks your very much. but the problem persists despite an intensive search.

Is it possible that my issue is that the camera projecting an image onto an object is the same camera used to bake the object, and that during the baking process, the camera internally switches and no longer correctly projects the image?
Could this be the case, or is it nonsense?
I cannot specify a different camera in the shader node Camera Data.
Doesn't it always use the current camera for projection?

I don't understand it.
Please try this blender file:

I project a UV-Color map in the material with camera data node.

material in the shader editor

when I look through the camera it looks like this:

Camera-Projection result

Here you can see the Scene setting. But you see the camera projection is now projected by the viewport camera.

Camera projection dont change, but viewer cam project the map

If I bake it with camera bake option the result is not the same like you can see through the cam.

Please help if you can

Is the resolution of the images you're using for front projection the same you're using in the new render? That's important.

If that's not the case, you'll have to use a Tranform Node and change the size values so they match the different resolution/ratio.

[JackMcRip]

The resolution for the image that I am using for projection must be the same like I user for the final texture map?
Or is the new render not the result that I will be using fot the texture?

[JackMcRip]

I have set the Render resolution to the projected image resolution:

It looks different, but not like the camera view.

That's all you need to do:

The X and Y scale control the aspect ratio of your image.
