Apex not working on multiple materials since 4.8
Hi, we have had APEX working before updating to 4.8, but afterwards we are getting an issue with skeletal meshes that have multiple materials. We have even reimported the same mesh and it has this problem though the source asset is exactly the same as what worked in 4.7.
The issue is essentially that any meshes with multiple materials applied will only render the first material ID (submesh 0)
Any other materials will not appear. This happens on our simple test case shown above, as well as the asset we discovered this issue (a cloak)
I have looked for solutions but cant find anything about it recently.
Sorry this one seems to have been overlooked apparently. If you ever find yourself with something like this where it worked in a specific version and then didn't in the next, this would be considered a regression unless there was a specific change that was meant to do that, which is usually detailed in the release notes. In that event, make sure to post it in the bug reports section of AnswerHub and we can make sure a tech is assigned to verify and submit a ticket.
I was able to reproduce this and confirm that it was working in 4.7. I have submitted UE-23300 for this to be investigated.
Once there is an update to the ticket and any relevant information to pass along I'll post back here.
