Hello UE-Community,

I´ve some problem with rendering my build grid on landscape.

Look on the screen to see the problem, its almost clear.

Grid rendering, for better visual the free tiles should be blue, the blocked red, but the colors are mixed.

Here you can see my base material as deferred_decal, the specific colors are created by instance materials.

I have tested every decal blend mode and played round about 3 hours to find some correct properties,
but i don´t get rid of this problem.

i´ve already tested the DBuffer, but then the pink tiles are also red whats not correct :frowning:

Only the two tiles in bottom right corner should be red.

what logic is setting the color parameter?

There are some instances of the Material, where the color is set as default and never changed in blueprint.
