Super knowledge ! Thank you !

[@HojDee]

You're welcome :)

[@nutwachi3002]

thank you this is so useful I wonder what is the best performance between using 1 material for 100 actors or 100 material for 100 actors?

[@HojDee]

1 material is always better. Material instances are cheap. Soif you want variationa, always use material instances

[@driizzlingrain6778]

good one 👏

[@HojDee]

Thanks :)

[@YOGESHKUMAR-ry1fz]

nice this is good info

[@HojDee]

I'm glad you find it helpful :)

How do you preserve the UVs? When i use merge materials option it creates new UVs. Thanks for the vid

[@HojDee]

When merging materials, a new texture should be created. And that texture needs a new UV. That's why the previous UV can't be preserved. That's what I think is the reason.

[@SchmirkoOff]

Good tutorial, but if I change the LOD Selection Type to "Use specific LOD Level", the "Merge Materials"-option still is disabled. Do you have any idea why it isn't enabled after that? Did I forget sth?

[@HojDee]

Hi! if you do it like the video, it should be enabled....maybe there's sth wrong with the mesh

[@SchmirkoOff]

@@HojDee Thanks for answering, however the mesh is nothing special. But I've got the theories now in the meantime, that it's either because all those Materials are in fact Material Instances or it's too much of them on the mesh (89).

[@HojDee]

@@SchmirkoOff send me the mesh, i'll check it later

[@berryrobot9825]

why there are two drawcalls with only one material?

[@HojDee]

It was a mistake from me. There's only one :)

[@Zarrar2802]

How to merge materials for skeletal meshes? Trying to merge a skeletal mesh has merge actors button greyed out with message "insufficient mesh components found for merging"

[@HojDee]

Unfortunately it's only for static meshes
