How to use CitySample - BP_AnimToTexture?

has anybody converted this vertex anim plugin to ue5 with success?
I did it after upgrading to 4.27, but have had no time to test it yet… there had been a lot of work with float to double and some other vector conversion…

btw its creator suggests to use the very similar AnimToTexture plugin made by Epic from the CitySample project. is it handy too, or is there docs somewhere?
