Material Image Mirror Problem

[Anonymous]

I trying to create a material for Topography  and use the sketchup snapshot to put as the appearance material. Please take a look below. I Imported and gave the offset as the image size, but the image when I see in 3D view in revit is mirrored. All the letters are inverted. What is going wrong. I'm attaching the image too.

Hello,

Based on your message I am assuming you:

1). Made a snapshot from google maps. (please check if the saved image is not mirrored somehow)

2). Created material in Revit 'manage materials'. (please check if image not mirrored in 'appearance' tab in the 'material browser')

3). Drawn Topography.

4). Chosen the created material at 'material and finishes' in the topography properties.

If this is what you done, and you checked the things above and the problem persists. I think there are three ways to solve this issue.

1). In the material dialog, go to the image and turn 'tiles' to 'none' at the 'repeat' category. If you now look at your topography and still see it mirrored the problem is somewhere else. If you see nothing anymore you can turn back on 'tiles' and play with 'offset' to possibly solve the issue.

2).If not solved, in the same image properties change the rotation to 180 degrees.

3). If not solved, you can solve the problem at the source and just mirror the image and hope it mirrors again like now.

If these al don't work please provide me with a couple of pictures of your material browser, especially the appearance and image tab.

@JvanReij Thanks for the reply.

I was actually exporting the snapshot from Sketchup so that the offset value remain with the topography.  But I used Lunapic.com to mirror the image and imported into materials browser and now it works, with the repeat settings set to none or tile, it didn't matter. But I'm still confused why it's mirroring in.

Goodmorning,

Great to hear it is solved, but yeah very strange it mirrors in the first place...

Have a nice day!

Hi Wayne,

Glad your problem has been solved, even if you have a mirrored image as the basis for your texture now...

There is a simple thing we forget to ckeck before exporting from sketchup: Normals.

When you check your sketchup model, display it with front/back materials (white and light purple by default)

All the visible faces should be white.

It means that the normals are oriented the right way.

I would gess the normals were inverted in your sketchup model, so the texture got inverted in Revit.

Tell me if it was the case!

Cheers,

François

Hello FGperraudin,

Thank you for the post, I didn't know this! I had the same issue and used simple mirroring to solve it, but this way works better.
