I have made a landscape material and everything works fine with the layers: Sand , **Snow **and Pebbles.
But when i try to paint with the layers **Brick **and **Grass **, the shaders compile and the landscape is locked with the Grid material , and no changes if i put the material in the slot again.
I use world compisition with 9 maps ( AA AB AC BA BB BC CA CB and CC).
The only thing i can do when the grid material fill all is to right click on the layer which dosent’ work and make , ***Clear layer *** , to get my work come again.
(I see Ue4 have put the layers for Brick in a folder names Map_AA_sharedassets and the others in a folder names Map_BB_sharedassets , but i 'm painting on Map_BB only for the moment , if it can help you to help me)
