I am working on an architectural visualisation projet that we need to send to the client tomorrow and this functionality not working is becoming a nightmare.
Usually when working on an object having multiple ID (for example walls inside a house) I just have to drag and drop the material on the part (ID) I want it to be applied to in the viewport. Now it doesn’t work anymore. When I do it it is applied to a random ID not related to the one I had in front of me.
What am I missing ? Is this a bug or did I turn off something by accident ?
Hi, would you mind sharing one of your meshes that has this problem. Some of these import issues should have been fixed already so there must be something about your mesh that is still causing the issue to occur.
To anyone having this issue. We have developed a plugin able to fix the discrepancy between LOD sections and ID’s. It works on both the actors in the scene and the source assets and it preserves the materials already assigned on the wrong ID’s.
While Epic fixes the issue you can contact me if you are in need of the plugin to fix an already corrupted project.
I have reproduced your issue in 4.14.3 however, it seems that the issue has already been resolved. I tested this in the 4.15 preview. Try testing this on your end and you will find that this should be working again.
If you are still getting errors just leave a comment here and we can continue the investigation.
Thank you for making this post and happy developing!
It is very possible you will run into additional bugs on the preview. For production or development it is always best to stick back to a more stable version (4.13) rather than go forward.
I merely suggested the OP try to test on 4.15 to confirm the issue is fixed on their end. That way making a bug report is pointless if the issue is already resolved.
I would never suggest developing on a preview build or a new engine release.If you do plan to migrate, do so with caution and expect bugs or issues. You may not run into any, but it is better to be prepared with back ups or copies.
