Mix 2 materials with displacement

[thanulee]

Hi, i wanna do some effects like mixing 2 materials, 1 with displacement and one without but idk how to do it since when i use a mix material the only workable displacement is in the mix slot. Any workarounds? thanks

Hi thanulee,
since displacement is evaluated before the shaders, you need to apply the same texture mix to displacement map, then use a baking texture node (from v 3.07-R2) to obtain a single displacement texture already masked, and plug it in the displacement node connected with the mix material.

Thanks a lot Bepe I ll try it 2morrow and if anything i ll get back at u.

I think i did it proper but it seems that baking texture is giving vertex map some artifacts. Also its very heavy and crashes a lot. Im using latest stable here.
Here is scene: https://www.dropbox.com/s/l17b3mjfrvgdt ... e.c4d?dl=0
Thoughts?

You can't use vertexmap in displacement. And keep away to use c4d shaders as you can. Prefer octane things if you crashes. And what's crashes you say?

[thanulee]

In general this scene crashes. Maybe is the vertex map before the displacement as u said.
So whats the way of mixing materials via vertex maps when 1 material has displacement and the other doesnt? ty

btw, vertex map through bake node works in displacement, but i have those artifacts as u see from the baking node. Is this a bug?

[aoktar]

Can i see bugreports or somethings else about crashes?
BUG is something that doesn't work as promised. Vertexmap is a hacked way which is emulated by plugin and requires uvset3. And octane displacement is not supporting uvset2/uvset3. yw

Open the scene and see thats why i attached it. Try play with vertex map in displacement. It displaces the object but it has artifacts due to baking texture node. And as u will play u will experience crashes.

If u forget this setup though, I ask again: how can i mix 2 materials one with displacement and one without?

Again: I've answered. You can't use vertexmap in displacement. It's not a matter of baking texture node. You can use baking texture to use octane nodes in displacement, but not vertexmaps. Pls read again my explanation. Also i couldn't get any crashes yet. GL!

I read it yes ok! But u dont answer to what i ask and to what this thread is about:

How to mix 2 materials one with displacement and one without?

Thats only thing i want to know. I wanted to do this mix with vertex maps and i never intended to use vertex map in displacement. I did it cause read what bepe told me.
