Camera mapping (1.30) Tweet

[roeland]

This script approximately maps a texture so it fits into the camera view. Note this does not take things like distortion and depth of field into account.

Updated for versions 2.26 and 3.01:

Additional features:

• the script also works for orthographic and spherical cameras (for cylindrical cameras it's not possible to correctly map the texture).
• You can camera map the environment texture by selecting the texture environment node (although it will look weird if you have reflections of the environment in your scene).

love this script

Is there any way to repeat the script on a folder of png files so we can have camera/projection mapped animation? I think I can do this in the blender plugin but checking if there is an easy way to do this in the standalone.

cheers,

Since we changed the texture projections for version 1.30 I updated this script. The UV transform doesn't need the (.5, .5) offset anymore, and the width given for the scale is the full width, not the half width.

Great script! I can't seem to get it working with Octane 3.0. Can someone modify the script to make it compatible?

[roeland]

The change to the resolution node in the render target broke quite some scripts.

When you get a complaint about a missing pin called octane.P_RESOLUTION, you can change:

Code: Select all

local resolution = rendertarget:getPinValue(octane.P_RESOLUTION)

to:

Code: Select all

local resolution = rendertarget:getInputNode(octane.P_FILM_SETTINGS):getPinValue(octane.P_RESOLUTION)

Thanks for the update an the Tip

[leehenshall]

Thanks roeland.

I did a find and replace using notepad++ then restarted Octane and attempted to run the script with the image texture selected and still getting an error in Octane 3.

See attached image:

Opps! sorry my mistake the fix does work. I just didn't have my render target selected/activated.

Thanks for the quick turn around roeland

The script is broken on V3.0, it cannot access P_RESOLUTION, and I don't know the syntax to fix it.
Can anyone help?

Thanks
Kind regards
