Hi all Apologies for bringing this up again. The distortion pipeline we have for Nuke is pretty good. Let’s say there is a plate which is 2048x1152 with loads of distortion. We make an ST map which is 2048x1152 and feed it through the right node and it undistorts the plate into the bounding box at…

@johnt , here you go. I also simplified it even further… [image] mochaLensDistort2020.zip Shared with Dropbox

@johnt I believe it is but I can make a 2020 version if you’d like. I should still have a version hanging around…

This is where we are at, at the moment. I am just trying to get a solid internal workflow so that when we get lens grids we can do it ourselves. We use Nuke for the grid analysis and then reformat the nuke clips so that we when we export ST maps we get the full bowtie extension. No lost pixels. I…

Rich, yep we’ve had issues with redshift and stMaps but it was operator error with the map not being used at 32bit. My stance was always “3d should be giving me back the correct distorted renders at source res”. But after some discussion we came to the conclusion that it’s easier for flame to do it …

If you have the possibility to make it 2020 that would be really helpful.

I’ve at some point used ST map lens distorts with negative values in Flame - you can work out from the values how far outside the bouding box it’s trying to read, then resize out to at least that size and use a CC node to multiply and offset the UV values by the same amount - like if you see -0.1 it…

Your process to CC the UV is interesting but yeah, that’s definitely a bit much of a process. I completely agree about undistorted plates not being cropped and I’d never want to go down the route. My interest was more in the re-distort process. When we outsource our tracking we almost always get ba…

Where can I found the matchbox 3d Equalizer ?

I think it is exported from 3DEqualizer and it is unique to the particular shot that has been tracked
