Landscape layers ending with _0, _1, etc. don't work

Result : only the layer not ending with _0 or _1 will actually render (i.e. Layer0 in the previous example)

Expected result : all 3 layers can be painted, no matter their name

This was originally reported in this UDN : [Link Removed]

• Create a material and use the following setup : [Image Removed]

(i.e. declare 2 materials ending with _0, _1 and one without a suffix)

• Create a landscape using this material
• In the landscape paint panel, create a layer info on each of the 3 paint layers
• Try to paint each of those layers

Landscape Material turns completely Black after Updating project from 5.1
