Hello and thanks for reading,
I am a beginner and succeeded painting material layers via vertex mesh painting. Now I recognized that painting on a 3D-Object like a box is possible, but not on a 2D-rectangle.
When being in mesh paint mode with a box as target and viewing the red channel, it looks like this:
Same thing on a rectangle doesnt work, I can’t even see the channels:
Thanks a lot!
This is the default plane
When you say ‘rectangle’, do you mean a plane?
You didn’t select paint mode, though…
Thanks a lot! Selecting the paint mode does not change anything. As you can see in the first image the paint mode is not selected either, but nevertheless the red channels mask is shown.
By accident I found out, that on one mesh Nanite was enabled but not on the other. As soon as I enable Nanite on the mesh, vertex painting is not possible anymore and the masks won’t be considered for texturing anymore. WHen re-disabling nanite, the layers show up as intended again. Is this a restriction in UE5?
This is the mesh with the layered and vertex painted material when NANITE IS DISABLED:
The same mesh, but this time with NANITE ENABLED:
Thanks a lot.
There are restrictions on what Nanite will handle. I wasn’t aware of this one.
You might try,
Nanite off
Paint
Nanite on
?
Since the vertex painted mesh will not show up when using Nanite there is no need to paint it then. It is not only impossible to paint vertex meshes on my Nanite object, they also disappear when switching on Nanite. However the vertex painting channels won’t get lost, they are available again when turning Nanite off.
The only solution until now is to turn off Nanite and keep it off.
Any ideas why that is? IS Nanite incompatible with vertex painted textures?
Thanks!
It’s only caching a simplistic fixed representation of the material at the moment, I assume. More fixes later…
