Hi,

Basic question

I understand that thin surfaces should show SSS(e.g. human ears), however I am getting the opposite, or I don't understand what I am seeing. For example, I render a rubber toy, its ears thickness is 0.07, and I set SSS Color = Red, Radius = 0.1. When I render, ears are opaque, while the body shows SSS?

Hello,

Just started to learn materialX and shading, and I have super basic questions:

1) Can I save .mltx material directly from Houdini, let's say I want to save a materialX shading network created in Houdini and load in other app?

2) Are there any "artist" friendly demos/tutorials on MaterialX (even outside Solaris/Houdini)? For example: This is how you setup glass or metal with scratches in MaterialX. PS: I found some tutorials but they are basic, eg create "mtlx standard surface" and add textures to base colors, roughness, etc.

Thanks for helping

Hi,
I am building an open world for a static camera shot. Near the camera, the terrain has high res, and in the background it's low res (cannot use high res for the entire terrain or I will run out of memory). I use the "terrain tiles" node to split the terrain into 3 tiles (near, middle, far). After processing each tile I convert each to a mesh.

My challange is when I display all meshes together they don't match at the borders. One solution is to overlap borders and upres, fuse points & average heights, etc...! Are there any better options? I am feeling I am reinventing the wheel here (maybe my workflow is completely wrong)?

Note: the reason behind the differences are things like mask blurs/expand, noise distortion that break at the border, plus each terrain might have different features (e.g only near camera there are puddles), so I cannot run the same nodes on each terrain uniformly ...
