Noit sure if this is the right forum, but I'll start out here.Rendo has the prop called "Flint Mountain" it comes with tress, grass and so on. There is also a winter add-on pack. I am trying to use the winter pack, But I can't get it to replace the grass and so on. Does anyone have any ideas on how to use this thing??

you need to link to something here so we can see what you are talking about.

In the case of both pictures, they are "straight out of the box" no dials or materials were changed. Is there not a setting to remove the greenery before ayou apply the winter add-on? I didn't see any in the zip files.

This is actually a query about "Flinks Ancient Mountains - Winter Add-on". Looks like the user simply needs to apply what the product description calls the "winter textures for 'ancient mountains' terrain and stones" to the mountains. These winter textures are shown very clearly on the add-on's product page:

You mean there's ANOTHER Zip? I thought I had them all. I went back and checked the 3 zips I have and I didn't see this one.

You need the base product and the add on.

I have all of them- and found out what the problem was. I loaded the original green prop, then loaded the "Winter textures..." thinking this would BE a texture. It's NOT. It's a separate prop that's supposed to load ABOVE the original. It didn't. It loaded beneath it. I had to go looking for it and raise it into view:

I think next time, I'm only using the one and not both.
