Textures disappear from landscape

i have some texture right now in my landscape,but lately when i add a texture in landscape Suddenly all texture disappear form my landscape. looks like i did not add any textures at all

i will be grateful for your help

You’ve run out of texture space. Just click on all the textures in your material, and in the details, change sampler source from asset to ‘shared:wrap’.


thank you so so so much

why when we connected with multi-user editing (by vpn) when one of us add a mesh (or something) the one who do not have that thing suddenly get disconnected from multi-user editing
