Matt Basher Posted February 23, 2016 Share Posted February 23, 2016 I am trying to render a steel table top with a custom perforation pattern in it. Rather than subtracting 10,000 holes from my table top, I am trying unsuccessfully to make a texture map that does this. For some reason the texture map that I have created is not editable; meaning that all of my controls in my Obj Info pallet are grey. Further, while the texture map is rectangular, the map comes through square, which stretches the holes. VW 2015 SP5 Designer Renderworks What am I doing wrong? thanks in advance.

Vectorworks, Inc Employee PVA - Admin Posted February 23, 2016 Vectorworks, Inc Employee Share Posted February 23, 2016 If you change the Map Type from Auto Align Plane to Plane, you should then be able to use the Attribute Mapping tool on it and asymmetrically scale the texture to get the aspect, size and alignment you need. This section of the Renderworks guide (at around 6min on this chapter) covers the basics of using Attribute Mapping on textured 3d surfaces and may clarify: Quote Link to comment
zoomer Posted February 23, 2016 Share Posted February 23, 2016 (edited) Further, while the texture map is rectangular, the map comes through square, which stretches the holes. This is a Bug/None Feature. Rectangular Textures work in every channel except in Transparency by Stencil Map. All non-square Texture files will get stretched to get square. And be sure that Stencil Maps will be b/w only, no gray shades. In that case it will take many times more render time. If you need grayscale Transparencies, use Transparency Texture Channel. Also in your case as it will give nearly the same result, without distorting. I normally use Perimeter Mapping. This will respect the size that you set in Material Properties. The Center for tiling will start at a corner of each Face. Edited February 23, 2016 by zoomer Quote Link to comment
AlanW Posted February 24, 2016 Share Posted February 24, 2016 (edited) Hi, What I do is to create my own textures in Photoshop. Find a perf picture you want then create a texture from it and then use the image in the transparency section and voula. See attached. The VW file is large because of the textures but if you cant work it out I can do a short Youtube video to show you. Perf Mesh.jpg is the image that you use to make the texture. Make sure you scale by image that way you dont have to guess it. You put in the actual size of the image. To get a nicer effect do 0 extrude other wise you have depth to the mesh which may work for you also. HTH Edited February 24, 2016 by Alan Woodwell Quote Link to comment
Matt Basher Posted February 25, 2016 Author Share Posted February 25, 2016 Thanks for the help everyone. I was able to make it work by making the map a square and crossing my fingers! I was never able to get the Obj Info options to work, so i never had any control on the placement of the pattern, but it works otherwise. thanks! Quote Link to comment
Andy Broomell Posted February 25, 2016 Share Posted February 25, 2016 you should then be able to use the Attribute Mapping tool on it and asymmetrically scale the texture to get the aspect, size and alignment you need. I've never been able to asymmetrically scale a texture or change it's aspect ratio in VW. Are you saying this is possible? Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted February 25, 2016 Vectorworks, Inc Employee Share Posted February 25, 2016 Ack, apologies, I was using a test version that had additional mapping options. They ARE something that is on the wishlist but it isn't certain that they will be going into the next version or not yet. No spoilers this early even for me! Quote Link to comment
Andy Broomell Posted February 25, 2016 Share Posted February 25, 2016 Well the fact that a test version even exists gives me hope! Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted February 25, 2016 Vectorworks, Inc Employee Share Posted February 25, 2016 We do want to dramatically increase the level of controls users have over texturing various object types, improvements are absolutely coming. We are going to tackle it from a few different angles. Quote Link to comment
Andy Broomell Posted February 26, 2016 Share Posted February 26, 2016 That is wonderful news! Coincidentally, the last two weeks I've been teaching my students about textures and mapping them to objects, and I feel terrible every time I have tell them "Vectorworks can't do that" (which has happened more often than I wish)... particularly after I've been telling them all along about how awesome Vectorworks is.

nplache Posted March 7, 2016 Share Posted March 7, 2016 There is a very simple work around for the problem of rectangular images for transparency maps. Use an image of the same size in the "Colour". I used the original PNG "Basher" provided and created the attached render. Quote Link to comment
