Copernicus ROP then File read error Transform not invertible 2024年12月10日11:17
I have the solution from sidefx team Midgardsormr via discord:
I cant say I understand how transforms work in COP context, in this situation.
From a developer: Yeah, Blend COP works in world space, considering the transforms of the background and foreground That error basically means that the projection matrix of the foreground onto the background plane is not invertible, so we can't resample it One degenerate case where this can happen is if the two images are perpendicular (e.g. one is looking down the Z axis while the other is looking down the X axis) If you don't care for the world-space matching, you should use Match Camera to get the foreground to have the same transform as the background before feeding them into Blend

Copernicus ROP then File read error Transform not invertible 2024年12月10日7:44
Hello,
I am trying to "cache" a stage of my copernicus workflow.
I created a ROP node and wrote an .exr
I then created a file node to read back in the exr and use it in my later COP workflow.
The issue is that as soon as I create a blend node to mix it with other nodes in my workflow, I get this error
"Warning Transform not invertible"
I tried setting colorspace conversion to raw in my ROP image output node, I also tried other output formats, setting Data Size to different settings and ticking raw, same for reading the file back in with the file node, I also tried using an OCIO transform node with various settings, no matter what I do, I cant read back in my file and use it with a blend node.
I also tried image/texture sampling it, project layer, I couldnt figure it out, is it a bug?

COPs ROP settings for color depth, channels, compression 2024年11月28日20:23
Hello,
I am trying to output an image from copernicus with a very specific setting for a game engine:
It needs to be TGA, single channel, uncompressed.
The copernicus node referenced in my ROP output node is set to MONO but the tga file output seems to be rgba, is it possible to output a single channel tga file?
In the ROP node I have tried setting Data Size to 8-bit integer but the tga file output is always 24bpp, is there a way to control the image depth?
I could not find any settings for the tga compression, the output is always compressed using RLE compression, is there any way to set to be uncompressed?
