I think I followed JIPS tutorial correctly for creating the correct shadow casting light mask node in World Machine (I also created it right in Gaea) but i think the problem I am having is I am not sure I am saving/exporting this file correctly from Photopea the online photo editor tool. I need specific steps to properly create the alpha channel and get casting just a faint transparent shadow of the mountains onto the ground......I got it working on the top layer but I dont think its correctly applying the transparency as the whole map layer mask looks too dark when I apply it
Top Level Alpha Light Masking for terrain shadows question
Which tutorial exactly?
I'd recommend using the Terrain002 shader. An explanation how the texture has to be made to give correct results is available here: https://wiki.faforever.com/en/Development/Mapping
