I have several small details in my model which I just assigned the grey system texture simply as a placeholder until I found a suitable texture to use. I thought I could just use the material replace option to just swap any face textured with the system texture with the texture I really wanted to use later without selecting each tiny little place the texture is used (VERY time consuming) but it doesn't seem to work. Am I doing something wrong? I open the material replace window and select the system texture on the left and the wood texture on the right which I want to use and click replace but it does nothing. Please help.

You need to have the polygons you want to work with selected. The quickest way of doing this is to select your object, goto Polygon mode, and then select all polygons by using ctrl-A. Then use the Replace Material function.

However, it seems to be more intuitive to just have an object selected when using the Replace Material function. A problem with that, would be that it then really replaces all materials of all polygons, which might not be what you want. Maybe the Replace Material function should have an option so you can choose. Something like "Replace materials in selected objects" and "Replace materials of selected polygons". What do you think?

What about that:
You will implement a "Select face by material", where you select an object or more, right click on the material button (in the Material Picker) and an context menu will pop up where you have the choice to "Select faces by material", and all faces which are having that material will be selected.
With that context menu, there can also be some other options to make material management easier, like "rename material" oder "delete material".

Rename material already exists. Confused

So does delete material. It's just that you have to go to the material editor for that and in case there will be such a context menu, why not include those functions there, too?

Yes, select faces by material would be a very nice feature or am I mis-understanding that it is already possible? Manually selecting just the faces I want to change is exactly what I am trying to avoid having to do. There are at least a few hundred small spots I want to change and manually selecting them is alot of work. And then if I decide I need to scale them once the texture is applied it usually unselects everything and I would have to do it all again if I didn't get it right. Maybe I'm still not understanding.

No no, it's right. It doesn't work yet, they still have to build it in. Right now, there's no other possibility than to select all faces yourself.

Then why not select all objects and then select all faces?

Because he only wants to select faces that are having a specific material. If you would select all objects and all faces, every face would be selected, no matter what material they have.

If you want to change a particular material in a scene, simply select all your objects, goto Polygon mode and select all your polygons. Then use the Replace Material tool by selecting the material you want to change, and the material you want it to be changed to. No need to select faces by hand - the Replace Material tool will determine which of the selected polygons should get the new material. I think that's what VD is trying to explain here too, he's right. Smile

Ah! Alright, I didn't know of this tool. Then, it's an easy way to do what he wants to do.

Great, thank you everyone. I was selecting everything in object mode and trying the material replace and it wasn't working. I switched to polygon and selected everything and it worked perfectly.

Still, a select faces by material option would be nice. I'm still now stuck with the problem of the material scaling being messed up and I still don't want to have to select each face separately to fix it nor do I want to mess up the scaling on all the other faces that are right already. It would also be useful if you were to change textures and needed to rotate just the new texture without having to manually select everything.

But, thank you everyone for all the help. Now that I know how the material replace works, it will be easier to test different textures for appearance.
