A good tutorial for using PBR materials in Rhino 8?

So I tried adding some PBR materials to my model. However, the sizes are wrong and often times the direction if there is a grain or direction. It used to be that I could edit rotation, scale, etc. None of those options show up in panel for the material. I have never gotten a handle on using materials in Rhino. I hope V8 might improve it for me. e.g. Say I’m want to apply a wood grain on a panel door, the grain is horrizontal and vertical. In the past I made a 0 degree and 90 degree versions of the material and assigned to surfaces as needed. I have no idea how to do it now.

Lastly, do PBR material make the files huge?

wood typically requires some texture mapping-
have you watched this video?

pbr’s can be big if the textures are 4 or 8k. Less so for 1 or 2k for obvious reasons.
