Hello,

I am trying to texture map a wall.

I used photoshoped to edit and save the image, and I loaded the image up as texture (tried both in JPG, and PNG format) to Revit material. However, when I rendered the wall it came out black.

Naturally, I thought I am making a mistake along the way so I created a new wall and assigned it a wall paper material from the standard Revit library materials. I set the view to render and it came out black again. In order to pinpoint the problem I created a masonry wall this time, again from the standard Revit library, and that came out fine.

Anyone have any idea what is going on?

I have attached the image of both walls side by side for reference.

Thanks a lot,

Show us these materials in a normal elevation view - non rendered - realistic view.  Need to see how intense the pattern is.

I have attached an elevation view of a wall with wall-paper material assigned to it. As you suggested, I changed the scale of the patch pattern from 8"x8" to 24"x24" and tested it for the render again, but it still rendered black.

 

See attached image 24"x24" patch scale, elevation-realistic view style.

 

Thanks a lot for your help

That material looks too intense for the scale of your view.

I am not sure if I am understanding you correctly. Do you mean that I need to increase the scale of the patch pattern, (so let say from standard 8"x8" to something larger)? If so, I increased the size up to 5'x5' and I got the same result.

Move ( or copy ) the image in jpg or png to this folder:

[C:\Program Files (x86)\Common Files]\Autodesk Shared\Materials2011\assetlibrary_base.fbm

 

the bold text can change depending on your OS and version

Hi everynoe,

I am really hoping I can get some help on this issue. I have exusted all the sulotions I could come up with. Here the problems and sultions that I have tested:

The problems that I am experiencing are as follows: 
  
Revit renders fine when objects are assigned standard materials, such as brick or glass, with the exception of wallpapers and a few more materials which are rendering black.
Every time I change the standard setting of a material that has been rendering fine, such as glass reflectiveness or color, Revit renders the object black.
Also, when creating a custom material from JPG or PNG images it renders black.
These are the solutions I have tested unsuccessfully on my own:
I tested the file in other computers and both the custom made and changed materials render fine.
On my computer, I have checked the link of the images and the path is configured correctly. I have also changed the density of the materials to different scales; for example, I have changed the scale of the patch images of wallpaper from 8x8 to 24x24, and still the rendering comes out black.
Thanks a lot,
Seeb

a question

Have you applied the update 1 to the 2011 version?.. that update make revit ( it happen to me on 2 different computers after apply that specific update, autodesk delete it from there) 

If the answer is yes... well sadly the only solution i found was format, reinstall revit. An external hd can be really handy at that moment.

  1. What did you copy the material from to get this one?
  2. Can you post a ss(s) of the material's rendering tab? 
  3. If all else fails, can you post a model with that material in it so i can look at it.
  4. Is this exterior, no artificial lights?

Thank you for the feedback.

I have uninstalled and reinstalled Revit a few times so far. Also, I have installed the 2011 service pack.The program itself is kosher and I have a stand alone licence for it. I have conntacted Autodesk as well, but the customer support is painfully slow and I am working under a deadline.

I belive the issue is not only this file. I have attached a sample rendering to illustrate the issue more clear: The first wall is a standard brick wall from Revit's template, the second wall was a generic wall that I have assigned wallpaper to (I have changed the scale of the pattern and no success), the third wall is standard curtain wall from Revit's library with standard glass material, and the fourth wall is the same curtain wall and glass type with only a change in reflectiveness of glass (from 15 to 30).

Also, I have attached the test file for you guys to take a look.

Thanks a lot

i'm not as familiar with rendering in Revit as I am in other programs, but usually when I see this problem, it is related to the ambient light reflective properties of the material.  There is obviously no light bouncing off of it, despite the medium toned color.  If there is someway to crank up those features, it would help. 

Otherwise, try deliberately overexposing the pattern in photoshop before you bring it into Revit.  If it's neon bright green in photoshop, maybe it will be normal green when you render it.

That would not explain the inconsistency of the rendering ability. Saying that I have tried to increase the exposure value, and no luck.

 

Thanks
