Mixed map

[glorybound]

Hi,

I am playing with a mix maps using a mask. My question is can I have a displacement modifier applied to just one of the mix map materials? I have material 1 with a grass texture, material 2 has a dirt texture, and I am using smoke as my mask. I have a displacement map on the object, but it is applying the displacement to everything.... is this possible ?

You'll need to create a slightly different mix map for the displacement, just replace the texture you do not want to displace with solid black.

Will that work with 2D displacement or just 3D?

[RErender]

Both, but 2d can only use one mapping channel.

[powerandrubber]

Yes the single map channel limitation has been a crux for me.

Hrmm.. I'm having a hell of a time trying to get this to work using 2D displacement. It's not bad on a small scale, using 3D displacement, but using it on an entire site will be painful. I'm using a GradientEdge texture to mix the texture maps and to fade the displacement map to black on the grass.

I like what you are doing. I would love to see your material setting for that. Can you share?

[RE:FORM_STUDIOS]

Yea, thats looking really nice.
I too would like to see your material setup.

MIX maps

I just wanted to bump this up so it stays alive. Up here in upper Minnesota we have a mix between grass and sand. I need to learn how to have a mixed material of grass and sand, just displacing the grass. I have tried a lot, but can't seem to get the look. Does anybody have any ideas?

This post so far has gotten be close, but nothing yet.

No problem. I normally create various masks in Photoshop; using the various terrain meshes or CAD file as a template. I came across the GradientEdge texture last week here and it certainly simplifies things; many great scripts/materials. I also noticed the ReplaceColor mask material, but I haven't had a chance to play with it yet. Anyways, this was done on a simple plane with the path cut out with a shapemerge. Here are the material settings:

Mat 1: Grass to dirt


Mat 2: Dirt to concrete


Mat 3: Displacement Mat
I set the gradient on this map to 2' so the dirt wouldn't displace too much and the grass would displace more the farther from the path.


Mat 4: Vray Displacement


I'd love to get this working with 2D displacement, but I'm having a hard time getting around the one mapping channel limitation.

Edit: Sorry for the late response; I wasn't around much over the weekend to check the forums.

Try vertex paint and paint a mask. The main limitation with it is the need for a dense mesh but it is a very intuitive way to work.

Here's another on a small site just using a texture; a displacement mask created in Photoshop mapped/repeated along a lofted shoreline.

[sea2stars]

Yeah.. I'd love to be able to use vertex paint, but on a large site it's just too much. If I need more variation with a mask I'll paint it in Photoshop and save it out as a grayscale PNG; very small filesize.

Mix

I like, I like a lot. I am testing out now.

gradient

How are you assigning the gradient edge to the elements? I don't see a way to use material id's so I am assuming you are detaching one your merged shape.
