Hey Guys,
I’m back home and have had a chance to look at the material. I’ve got it working in forward rendering - and have uploaded the update to Unreal. You should be able to update the plugin at your end.
Because it is an experimental solution, I didn’t want to permanently change the base material. I’ve included a ‘MAT_TerrazzoFlooring01_forwardRender’ along with the original material (in ‘Materials/Flooring’ folder). To get it working with the base geometry, you just need to open ‘INST_TerrazzoFlooring01’ and change the parent material to the material mentioned above. (If you want the materials to work in the example map, you’ll also need to adjust ‘INST_flooringLevel01_base’ the same way). You’ll also find MAT_wall01_forwardRender along with the original wall material in the ‘Material/Structural/Wall01’ folder. Follow the same process for ‘INST_wall01’ and ‘INST_wall02’ (just update the parent material).
I only update version 4.20+ - if you need an earlier version, let me know.
