Therre’s an issue with the VrayMultisubTex map whereby the map loses it’s selected options after opening the file with an older version of vray 5. For example, I had set up a material uising a VrayMultiSubTex random parameter set to “by element”. A colleague who didn’t have the most recent updates installed opened the file and resaved it. When I opened that file again, I discovered this map no longer had “By element” selected any more. On closer inspection it seems that the interface for this map has changed slightly in recent updates, and as a result backward compatibility has been lost.
Hi, V-Ray is developed in such a way that if you open a file created in an older version it works with the newer version. If you created a file in the newer version and you try to work with it on the older version we can not guarantee this will be trouble-free.
It is best if you could update all your team’s V-Ray versions to the latest one available on our download page.
In addition are you using the latest V-Ray version from our site - V-Ray 5 for 3ds Max, update 2.2 released on 16.12.2021 ? One of the older builds had indeed an issue with VrayMultisubTex backwards compatibility (internal ID VMAX-11542).
Yes. we are all updated to the latest one now, but one of the team was using an older version. I believe it was Build 5.10.01. Which build had the backward compatibility issue fixed? I couldn’t find anything in the changelogs regarding this.
The changes happened in Update 2. If you are using any of the new random modes or a combination of them - this is no longer backwards compatible.
ok, but why wasn’t this noted in the changelog?
