Tim Stullich (tstullich) added a comment to T60542: Fisheye lens results in Window projected textures being mirrored across X-axis.

I tried verifying if the inputs are correct for the camera_world_to_ndc function and I am not sure they are quite correct. One thing I tried doing was changing the variables P and the kernel_data.cam.worldtocamera matrix such that the output moves into the correct position, but I did not get very far with that.

I was able to trace down some things to direction_to_fisheye_equisolid but I am unsure of how that function was implemented. @Brecht Van Lommel (brecht) is there some documentation on how the equisolid fisheye lense was implemented?

Tim Stullich (tstullich) claimed T60542: Fisheye lens results in Window projected textures being mirrored across X-axis.

Ok, I will take a look around and try to find the source of the bug

Hello, could you post the output of the assertion that fails? This would be helpful in trying to find the source of the problem

Tim Stullich (tstullich) claimed T54697: Vertex color baking for Cycles.

Going to do some research into how vertex color baking is done in BI and will formulate a plan on how to adapt it to Cycles code.

Sorry I have been absent from this for a while, but I am now picking things back up again. I was able to find this snippet of code in source/blender/draw/engines/eevee/shaders/lights_lib.glsl line 283:

@Brecht Van Lommel (brecht) I was able to work on implementing some backwards compatibility logic in version_update.py and now I need to work on integrating the above changes into Eevee, as you had mentioned. Where would I start to look into making changes for Eevee?

@Rachit Jain (j-rachit) are you still working on this? The last comment you made was almost two months ago. If you are not working on this could you let me know and I'd be happy to take over from where you left off?

Yeah, I am thinking I might be a little in over my head with this bug, although it has been fun reading up on MIS and BSSRDF concepts and getting to know the code base.

Ok, so I started taking a look at the shader code but I am having a hard time understanding it all, even with the reference paper in the comments. Is there a way to debug the shader code when it is running?

Hi, I am interested in trying to fix this issue. I was wondering in which files would I need to look in order to start tracking down the source of the bug?
