Christiaan Posted February 16, 2012 Share Posted February 16, 2012 How do you extract an image from an existing texture? I want to create my own brick textures by starting with the existing ones. Quote Link to comment
Christiaan Posted February 16, 2012 Author Share Posted February 16, 2012 Found it. Right-click on texture in Resource Browser and choose "Extract image" Quote Link to comment
Horst M. Posted February 16, 2012 Share Posted February 16, 2012 You could also check out if the Shaders --> Tiles --> Option "Brick" can do something for you. Quote Link to comment
Christiaan Posted February 16, 2012 Author Share Posted February 16, 2012 Ah, interesting, thanks. Quote Link to comment
Stan Rostas Posted February 16, 2012 Share Posted February 16, 2012 Christiaan, If you are using the procedural shader as opposed to an image shader than you cannot export the texture as an image directly. The only way is to create a panel in front elevation, render, then save as image. If you are using an image shader than this should be added as a image texture which can then be saved off to your desktop. You would navigate to that texture in the RB then Extract Image(s) Opens the Browse for Folder (Windows) or Export Image File (Macintosh) dialog box to save a .png file extracted from the selected resource To extract images from all image-based textures, Renderworks backgrounds, and image resources in the current document, execute this command with no resources selected. Then you can edit as you need in your fav image editor Quote Link to comment

Christiaan Posted February 16, 2012 Author Share Posted February 16, 2012 Tried it but I just get this mush (top one): Quote Link to comment
Horst M. Posted February 16, 2012 Share Posted February 16, 2012 DId you get the mush from the Shaders? :confused: Quote Link to comment
Christiaan Posted February 16, 2012 Author Share Posted February 16, 2012 Top man (or woman?), thanks. I don't know what I was doing wrong. Quote Link to comment
Horst M. Posted February 16, 2012 Share Posted February 16, 2012 Looks like you forgot to burn them. Quote Link to comment
Christiaan Posted February 17, 2012 Author Share Posted February 17, 2012 As soon as I start playing around with the sizes (bricks are 215 x 65 here) it all goes mushy. I must me getting something wrong with size. There's a size field in the main window set to 100 mm. I changed this but it didn't help much. The shader looks fine in the Colour setting window.

Vectorworks, Inc Employee Tamsin Slatter Posted February 17, 2012 Vectorworks, Inc Employee Share Posted February 17, 2012 Hi Christiaan Sending you an example of a UK brick texture. I find that attempting to change the size field seems to kick it into action - it prompts you to use the specific dimensions you have entered rather than using the main texture size as a scale factor.

Horst M. Posted February 17, 2012 Share Posted February 17, 2012 Hi, I've played arround with your File. The mush shows only in Open GL. FRW FQRW and so on show the Texture. I adjusted the texture. I have no clear idea why the Shader has a - Size field on the Main window, a - Scale Factor (%) on the Shader WIndow of the and again - input Fields for Brick Sizes. I adjusted the Texture by editing all those fields kind of randomly. The Size Input field on the Texture is somehow monitored by the Plugin if the Input makes sense .... ???? I would appreciate a clarification from the Nemetschek Maxon Team how these Fields work together. Quote Link to comment
Christiaan Posted February 17, 2012 Author Share Posted February 17, 2012 I managed to de-mush with the help of a file Tasmin sent me too, although I had to adjust size in the main window. I'm pretty happy with the results, so the engineering is good. Pity about the design of the user interface. Thanks for your help guys. Quote Link to comment
Horst M. Posted February 17, 2012 Share Posted February 17, 2012 Have a Theory: The SIze on the Main WIndow is the SIze of the repeated Pattern The SIzes in in the Shader window are multiplied with the Scalefactor and generate the Pattern in the SIze given above to be repeated.... I will explore that later. Quote Link to comment
Horst M. Posted February 17, 2012 Share Posted February 17, 2012 (edited) Nice result!. I always try to use shaders before i use image textures. I would like to ask one question: Christiaan, how did you get this corner Windows built? I tried something like that, wiht a Mullion on the Corner edge with no sucess.

Christiaan Posted February 17, 2012 Author Share Posted February 17, 2012 Is it possible/practical to create other types of materials using the shader without an image, like say, vertical standing seam-type metal cladding? Quote Link to comment
Vectorworks, Inc Employee Tamsin Slatter Posted February 17, 2012 Vectorworks, Inc Employee Share Posted February 17, 2012 The size field does control the size of the preview square within the shader editor for Tiles and Noise shaders, however, in 2012, there was a change for the Brick shader editor in that the values were supposed to be just real world and therefore the size field should not mess it up. Maybe some clarification from Dave D would be useful. Quote Link to comment

Yes it is. The Tile shader has a lot of possibilities also for Vertical and horizontal Strutures. Quote Link to comment
Christiaan Posted February 17, 2012 Author Share Posted February 17, 2012 Fantastic. Why is there not a huge library of textures using this method? Much better than images. Quote Link to comment
Vectorworks, Inc Employee Tamsin Slatter Posted February 17, 2012 Vectorworks, Inc Employee Share Posted February 17, 2012 It's really good fun making your own! Have a look at the Noise shaders too - lots of pretty stuff you can make. Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted February 17, 2012 Vectorworks, Inc Employee Share Posted February 17, 2012 Yes there is an interaction between the Edit Texture Size field and the bricks still. There shouldn't be - the whole idea of changing the bricks dimension to be self-contained was so that people could say what size bricks they want and the texture size would not affect that. Anyway if the blurry grout shows up in a RW rendering then the Texture Size should be set closer to the object size. For example the default texture size of 1" can show the blurry grout lines if the bricks are say 1' or so. In that case the texture size should be made bigger to get rid of the blurry edges. If this is OpenGL only then a somewhat blurry texture is expected - for shader-based textures VW uses the thumbnail shown in the Resource Browser to render the texture in OpenGL. Since shaders can repeat infinitely they cannot be shown well in OpenGL as images unless the images go on for a very long way to hide the repeats. Quote Link to comment
