Yeah, sorry I changed it right after posting the reply and didn't think it would be a problem.
This is about V-Ray for Cinema4D. In this scene there is a softbox texture(in the V-Ray material diffuse slot). Here the base texture of the softbox(the checker in the screenshot) is lost after loading the scene in 2024 and using the code in the original post, but loads fine in older versions. The old TEXSOFTBOX_BASE_TEX_TEXTURE=613662896 became TEXSOFTBOX_BASE_TEX=1404507874 and the issue should be reproducible with any V-Ray build for C4D 2024 from the last year.
Note that this isn't something critical as we only do it in a few places, however, it is slightly annoying
and mostly wrote to check if there is something obviously wrong with what we are doing 
.
