scaling roofing material?

[philvanderloo]

I imported this Revit structure and applied an edit poly modifier, then applied a roofing material to all the polygons using autodesk bitmap

No matter what I do, the roofing renders scaled way too large and I can't seem to change it.

It seems to be close to the right scale in the viewport but it renders large. When I try to scale the material in the material editor it just slides up and down or sideways. What am I missing?

Thank You

try a reset xform modifier on it from utilities tab. **save right before you try if it is linked geometry

 

your uvwmap modifier should be on top of reset xform on the stack

I watched that video before posting this Ismael. Problem is, that entire structure was created in 3ds Max. Mine was created in Revit and imported and behaves COMPLETELY differently.

First of all, I have to apply a edit poly modifier to enable me to select individual roof polygons like in this video. Then, when I apply a uvw map modifier, select a roof polygon, the polygon is solid red, Unlike in the video, and I get a different gizmo which doesn't allow me to do anything but move the entire roof.

In the video you attached, when a roof polygon is selected, it doesn't turn red and you can still see the roofing material as you manipulate it with the gizmo.

Not working like that for me.

Importing from Revit is a complex undertaking and I'm making very little progress figuring it out.

Re-setting xform made the entire roof very tiny and disfigured and threw it way off to the side.

In the video they selected the polygons, applied UVW map and then scaled the Gizmo of the UVW map they just added. You applied the UVW map then went down to a sub-object level poly...

Ismael,

Maybe I'm missing something here but, until I added the edit poly modifier, I was unable to select individual sections of the roof like in the video. The roof was one entity, (editable mesh), and I could select all or nothing.

All I'm trying to do is figure out why my roof material scale looks right in the viewport but still renders huge.

I've tried everything I could think of 10 times over and no matter what I do the scale of the shingles renders the same size. Changed the scale in the material editor and the modifier panel, (among many other things), and nothing has any effect.

Phil,

If you want selected polygon to not display solid red hit f2 key. Are you using real-world size w/ your material bitmap?

[salvador]

Phil, it might sound crazy, and you don't need anymore crazy right now, but just faintly it looks to me like the tiles scale is correct, but the bitmap you are using has some "darkening" around the edges and this is causing the problem; you are not seeing a huge tile, but one "tiling" item of your bitmap (was that clear?).

I suggest you set your scale correctly again, but try another bitmap and make sure it "tiles" seamlessly in Photoshop. Also, put a bump mat in your material to see if you start getting some better look.

 

If I'm crazy, just ignore me, he he he. . .!

[philvanderloo]

Well that got me there Salvador. You were right about the bitmap scale being correct. The problem was, I was using the same image as a bump map and that scale was way off. Thanks for the contributions all.

Glad to help

There are some very good, realistic looking roofing materials available for scale model structures, but once in a while a project comes along that just cries out for something special. Creating your own realistic looking shakes is not as difficult as you might think, and the results are worth the effort.

"Barn Shakes" were a little thicker, and sometimes wavier version of hand-split shakes, and were often a bit longer - 24" as opposed to 18", so you could get a little more coverage per square.
