I got to test my asset with Vulkan at 4.19 since it is not working still at 4.18, thou I dont receive any errors. the material is just invisible atm.
PS: I tested and there is still issues. Main material is still invisible and I also noticed terrain at certain distances start to show artifacts that looks like black triangles. Im using raymarching and custom hlsl nodes, that works perfect for sm5. I was expecting at least for the remain of the scene that performance would be better but I am getting 1/2 FPS of I can get with sm5. If I set screenpercentage to 200% it is showing even worst performance than expected. I know the code is still wip but as I said, I was expecting more.
