I’m having an issue with my material fill. The building you see is a Hover model, I used Fredo6 TopoShaper for the terrain and when I start to create shapes and fill them, they don’t seem to sit over top of the terrain, rather they are mixed together. When I render through V-Ray, it also creates a sort of pattern on the concrete when there should not be any. Thoughts?
Looks like some z-fighting which occurs when more than one face is trying to be in the same place and the graphics card can’t identify which one is supposed to be in front. Remember that faces in SketchUp have no thickness so you can’t just lay one flat shape over another like you’re putting a bed sheet on the floor.
The z-fighting will also occur when faces are very close togethere camera to face distance. This means that as you zoom out you can get bleed-through of a face under another. The appropriate thing in your model would be to either divide the terrain surface into regions and apply different materials or cut away the terrain and insert the smaller region in the hole.
It would help us help you if you shared the .skp file.

OK, how would I share my .skp file? It looks like its to large to upload
Upload it to DropBox or WeTransfer and share the link.
You shared the .skb backup file, not the .skp working file so it may not match.
Yes, I realized after uploading. Here is the correct format.
So the issue is indeed z-fighting. You have the face of the laying directly on the terrain.
Use one of the options I gave you. Either divided the terrain surface into different regions so you can apply the concrete texture to the correct region or cut an opening in the terrain so there’s no terrain surface under the concrete.
Here I’ve made the terrain a solid object by exploding the skirt and giving it a bottom face. Then I extruded the concrete shape to give it thickness and made it a solid object. Then I used Trim from the Solid tools to cut away the terrain where the concrete is. The concrete has thickness and volume and the terrain has a void where the concrete sits. A lot like the real concrete on the real terrain.
By the way, you should get into the habit of keeping your models lean and clean. I went through your model and did my usual cleanup procedure. First I fixed incorrect tag usage. ALL edges and faces should be created AND remain untagged.
Then I purged unused content. There’s really no need to keep all those unused components and materials. They just create file bloat.
This cleanup reduced your .skp file by more than 80%.
This file has the extruded concrete.

When you are finished referring to the 2D site plan, you should delete it as well.
I played around and think I got it all figured out. Thanks for your help!
